Sakamaki Izayoi

Izayoi Sakamaki is the main protagonist of the series "Mondaiji Tachi ga Isekai Kara Kuru So Desu Yo?".

Appearance
Izayoi has light blonde hair spiking downwards in all directions and a set of purple eyes. He also wears his headphones to keep his hair under control. He wears a dark blue gakuran and keeps only one button in place, the rest are unbuttoned to reveal a yellow undershirt beneath the uniform. Izayoi also wears pants of the same color and a pair of tennis shoes with black, white and gold tones.

In the later parts of the light novel, his headphones were destroyed in the Underwood story Arc where his gakuran was also torn in battle, and made into makeshift bandages for Gry when the latter was injured. After that saga, Izayoi's new set of clothing consisted of a yellow shirt under a red zip vest and a black jacket. He now wears gray pants in place of his old ones and he is still seen wearing his old tennis shoes for footwear.

Starting Volume 11 Izayoi wears a plain black shirt, khaki trousers and brown boots after his outfit is ruined during his fight with Azi Dahaka.

Personality
Izayoi is a very unpredictable young man that uses brute strength to solve everything and pursues a good fight. He easily described himself as a vulgar, savage and a hedonist who is hopeless, which makes sense as he can be fairly perverted as seen by his comments with Black Rabbit, making jokes about her body and wanting to claim her virginity. Be it a Gift Game or a simple cooking contest, such as the one in Volume 8 side story Lily's Big Adventure, he only participates in things that are deemed interesting to him. He enjoys challenges and will even participate in a Game with a handicap so long as it makes the Game more enjoyable.

Despite these traits, Izayoi is surprisingly intelligent, having solved the riddles to all the Gift Games presented in both the Anime and Light Novels and showing an in depth knowledge of many subjects, ranging from mythologies, concepts and even architectures. He mostly spends his time in a library reading, showing his studious nature. He is also shown to be a forgiving person so long as the guilty party is conscious of what they have done and show guilt while being forthright about it.

Izayoi's arrogance does not falter but he knows when to back down in a fight, as shown in Episode 2 where he conceded defeat to Shiroyasha, showing his confidence is not just arrogance. One of his more suprising traits is his loyalty and care for the Community. Originally joining for the fun of it, he showed a caring nature for the people within the group and constantly makes plans to improve both the group and its reputation.

In the end, Izayoi is the type to follow his own rules and morals, such as only using a strong power to fight the strong and is merciless to whomever is his opponent, whether a god, comrade, or Demon Lord. His constant search for enjoyment is seen as a bother, but the charisma he wields is enough to draw people to him to follow. He will not tolerate anyone who goes against what he believes, such as when a criminal targeted children, he willingly hunted down the Demon Lord responsible as he believed that children were the weakest of society and should always be protected regardless of their power levels. However, because he knows how different his abilities are from the others, he feels that he has no one to depend on and thus often taking on all the burdens himself.

His only rule and main goal in Little Garden is "to have fun."

Relationships
Shiroyasha - She is one of the few people Izayoi seems to hold some respect for. He was willing to give up on a duel against her and decided to allow her to "test" him. Later, Izayoi goes to her for advice on a certain situation. It's unclear whether Izayoi respects Shiroyasha because of her strength and power or her perverted nature they both share.

Black Rabbit - It is shown that he and Black Rabbit have a constant relationship. He usually jokes around her like harassing her or pulling her ears. He is aware of her powers and behaviors. He quite often plays with her like he wants to have all the fun to himself instead of letting Black Rabbit get all the fun. He also went insane when she got hurt.

Kudou Asuka - It is shown that he and Asuka fought when they first met, and later became friends. In Episode 6, he saved Asuka when they were escaping from an angry Black Rabbit who was riled from a pank they pulled for fun. As the anime goes on, Asuka starts respecting him more for his knowledge and ability. They are friends and the main force for their community.

Kasukabe You - During the period when You was bedridden due to the Black Death infection, Izayoi had sat beside her bed reading nonchalantly and claiming that he was doing so just to have a private space in the quarantine room. He also forgave her readily when she told him that she had damaged his headphones beyond repair. He pretended not to know that Calico was the one who had stolen his headphones and gave up on his chance to participate in the Harvest Festival opening ceremony. She believes in his strength as she stopped Asuka from using her full powers upon seeing Izayoi's arrival. They are friends and the main force for their community.

Jin Russell - Izayoi's good qualities rub onto Jin. He seems to look up to Izayoi very much, listening to him and trying to keep up with him. In turn, Izayoi helps out with the planning of the Community's future such as helping to suggest plans that would guide the Community to gain more potential allies and build its reputation. They also spend much time in the library together, in the No Name Community grounds, researching on ways to get their lost comrades back.

Leticia Draculair - Leticia was first one to ask him about his past and knows the most about him. She was surprised when she heard of his foster mother's name, Canaria, who was also the previous leader for the Community before it fell to the Ouroboro's attack. When Izayoi defeated her in the battle of the huge Dragon, she officially becomes the chief maid of the Community and refers to him and the other problem kids as her masters.

Percher - Participates actively in Izayoi's plans that include lots of fun. This is shown when she is seen battling Asuka to make her see the difference in powers, or even making others irate at a big conference. Though when she goes too far in her pranks, Izayoi would rein her in with threats that make her tremble all over just at the thought of it.

Shirayuki-hime - The snake water god that he challenged on his first day and obtained the water sapling from. She then invites him for a game in her territory once more when Shiroyasha asks her to. They played hundreds of games with each other all of which she lost to him and finally becomes the third maid of the Community due to the uncompleted repairs of her temple being delayed.

Baron La Croix - He helped Izayoi choose whether to stay in his world or leave to save the little garden.

Background
Before the events of the story Izayoi was placed in a foster home. Often he was adopted but found himself back at the homes due to him being too much for the parents to handle. The orphanages eventually grew sick of that as well for they started to dump him from one orphanage to another. Eventually, he grew sick of the way he was treated and while used by several people, he managed to get back at them by swindling them out of a decent amount of money. Using this money, he decided to host a game. The goal of the game was to find him, basically hide and seek. He would give prize money if someone found him before the time limit. If they failed to find him, he would probably go on a rampage because the world was too boring. He played these games to find someone on his level.

Canaria found him three minutes before the time limit and made him admit defeat. Canaria proposed another game. If she won, he would be her son. If he won, she would play with him for the rest of her life and provide a wonderful place for him. With this, they both went around the world for two years. During this time, he learned many things and became an expert on mythology.

During their time at the Iguza Falls, Izayoi is heavily disappointed when he learned the 'Demon of Iguza' did not exist. Canaria decided to take him to a nearby village to show him how people lived there, and to a nearby dam, teaching him about the modern world's alchemy. Izayoi, filled with excitement, decided to destroy half the dam with a punch, causing both him and Canaria to flee the country.

They traveled around the world until Canaria made an orphan institution to help children like Izayoi.

When Canaria became ill Izayoi decided to fulfill one of her wishes, which was to attend high school.

A year after Canaria's death, he received a letter from the sky, and a call from the CANARIA Welfare Organization saying there is a will left to him. Arriving at the foster home a few days later, he reunited with Suzuka and Homura, the latter being responsible for the creation of his headphones.

Later, he met with the lawyer who presented Canaria's will to him. After reading through it, he is shocked upon learning that Canaria predicted the time of which Izayoi would read it and had offered a new game: If Izayoi couldn't find her in the specific time, she would then spirit away everyone in the center. Izayoi solved the clue and confronted the 'Lawyer' responsible for the disappearances.

The Lawyer introduced himself as Baron La Croix, a Lao (the word for god in Haiti language) who rules over Death aka Death god. He challenged Izayoi in a world that exists between Life and Death, fighting him to get Izayoi to be truthful to himself. To further this, he began collapsing the area around them, giving Izayoi the pressure of releasing his power to their fullest potential or die, losing the game and all the children at the foster home.

Izayoi manages to draw out a bit of his true power and annihilate the miniature world around him. He awakens to find that everyone has been returned and that Canaria knew he would defeat Baron. She tells him the moment he opens that letter attached to her will, he would be summoned into a world where the battle that he just fought was an everyday occurrence. As such he is given two options; remain in his world and live a carefree life, or head into the battle in the new world by himself. After some thought he chose to open the letter.

Volume 1
After receiving a letter, Izayoi arrives in Little Garden alongside Kudou Asuka and Kasukabe Yō. His personality caused him to have a mild conflict with theirs.

Being the first to notice Black Rabbit's presence, he was similarly impressed by the fact that another girl, Yō, was able to detect her as well. Izayoi took the initiative to charge forth and dragged the fellow out of her hiding place. However, he was awed by his find, taking an interest in her appearance (rabbit ears). The rabbit introduces herself as Black Rabbit and Izayoi is told about the workings of the world, Little Garden and the Gift Games. Black Rabbit challenges Izayoi to a trial Gift Game which he won easily.

Izayoi traveled to the Edge of the World, Tritonis Falls and challenged a Water God to a Gift Game and receives a Water tree sapling as his Gift for winning the Game. Izayoi chooses then to confront Black rabbit for the truth as to why they were summoned, easily deducing that the community was in trouble. However, Izayoi still agrees to join the No Name and to aid them in the reclaiming of their lost name and banner (though it was only because he was interested in Black Rabbit, who was a caliber above the rest of the Community, that he joined and to find the reason why she is still holding onto the community and not changing it's name and banner into a new one).

Shortly after, Izayoi learns about the Gift Game Asuka and Yō will be participating in against Fores Garo and refuses to help, saying they are the ones who joined and will be the ones to participate. That night, he finds several of Fores Garo's members snooping around the [No Name] territory in hope of kidnapping the children of the communtiy and stops them. He declines to defeat Galdo, but promotes Jin to be the symbol of the Community that had no name. He did this so that the community had something to symbolize them and to make the declaration to fight against all Demon Lords to spread word of their Community for their lost members to have a lead on them. Later in the night, Jin confronts him about his action and Izayoi explains himself. He then learnt about how a former Demon Lord used to be a member of the core group of [No Name] and promises Jin to help regain that comrade if he wins the Gift Game tomorrow.

The next day he and Black Rabbit were forced to wait on the outside of the game grounds. Izayoi asked if they could take a peak, but Black Rabbit clarified that since the Geass Roll did not give the permission to witness the game, they would not be able to do so. Consequently, Izayoi called her useless for not having the authority even as a Judge Master. Once Galdo is defeated, the forest disappears and they are allowed to enter, where they then find a critically injured Yō being cared for by Jin. While Black Rabbit took Yō back to the [No-Name]'s base to be healed, Izayoi and Jin went to speak with the communities forced into service by Fores Garo, where Jin returns their names and banners. Izayoi also takes the opportunity to tell the other communities about the No-Names' plan to defeat the Demon Lords, asking them all to remember Jin Russel's name.

Later that night, Izayoi was assaulted by a mysterious girl who revealed herself to be Leticia Draculair, the former demon lord whom Jin wanted him to win as she is offered as a prize in a Gift Game. He learns that the reason, for her assault and the assistance she had given to Galdo Gasper in the Gift Game, was to test the abilities of the children summoned to Little Garden. Izayoi learns that the gift game was cancelled and took Leticia on her offer to test his abilities. He manages to surprise the vampire and the game is interrupted by Black Rabbit, who reveals that all of Leticia's Divinity is gone and all she had left was her "Lord of Vampire" Gift.

Leticia was re-captured by [Persus] through the power of the Gorgon's Eye, and Izayoi had to stop an angry Black Rabbit from assaulting the community. He suggests going after the boss of the group, and ends up joining Black Rabbit and Asuka at the [Thousand Eyes] shop to discuss with Laius. During the negotiation, the trio of Shiroyasha, Asuka and him decided to make jabs at the moon rabbit just for fun. The negotiation fails and Izayoi repels the attack directed at Asuka for Laius was provoked into action..

Shortly afterwards, he talks with Shiroyasha and learns about the Gift Game that grants a community the right to challenge Perseus. Clearing the prerequisite Gift Games in a solo mission, he delivers the gifts that would proof the right to challenge to Black Rabbit, allowing her to issue the challenge to [Perseus].

Before the game began, Izayoi assigned roles and a strategy for the participating members to fulfill. He, along with Yō, succeeded in taking the Helmet of Hades and a copy of it.

Volume 2
Upon receiving the letter, Asuka located Izayoi in the library and he decided to get back at Black Rabbit for keeping secrets. Hence, together with Yō and Asuka, they left a letter challenging Black Rabbit to find them or they would leave the Community for real. After deciding to head to Thousand Eyes to get Shiroyasha to take them to the Northern Side of Little Garden, Izayoi is given a detailed reason as to what Floor Master's are and why it was requested that the [No Name]s participate in the festival. Afterwards the group was teleported to the north side in the [Salamandra] Community.

Once they arrived Izayoi, Asuka and Yo were attacked by Black Rabbit. Izayoi grabbed and Asuka and ran from the Moon Rabbit, arriving in a shopping district where they lost her. Izayoi then accompanied Asuka as they explored the district and came upon a tektite glass statue of [Salamandra]'s first leader made by Sala Doltrake. Izayoi showed his knowledge in various subjects by describing the material the statue was made out of to Asuka. After learning of Asuka's past and her fascination with Halloween, he decided to plan their own Halloween with her by finding Gifts that could increase the fertility of the farm land. Black Rabbit found them initiating a chase between her and Izayoi as Asuka was caught by Leticia.

Izayoi then challenged Black Rabbit to a game of tag, where the winner would be able to command the other to do one thing. The game ended in a draw, much to his chagrin. Their game however garnered the attention of the [Salamandra] military police and were taken to the main base. They were immeidatly chatised for their actionsby Mandora Doltrake, but the new Floor Master Sandora Doltrake forgave them since Shiroyasha said she would cover the damages of the game. Shortly after Sandora greeted Jin and Lily, revealing that [Salamandra] was once an ally of the old [No Names], Mandora attacked them leading to Izayoi to step in and block the attack.

Getting them to back off, Shiroyasha revealed to those remaining that a member of Thousand Eyes had recorded a prophecy where a Demon Lord would attack during the festival which was the reason she had brought the [No Names] with her. Izayoi predicted some were displeased with the new Floor Master being a child and expects that some expect Sandora to fall. Agreeing to protect the town with the others, Izayoi agrees to waiting to fight until then, but asks if Shiroyasha would be displeased if he so happened to take out the Demon Lord before she could act.

At the inn, Izayoi took part in teasing the girls after their bath before attending the meeting to discuss the next day's Gift Game. Once the participating community's names were revealed, Izayoi remarked about the name Rattenfanger being related to the Pied Piper of Hamlin, and when inquired about it, had Jin answer for him. Once the meeting was adjourned Izayoi and the others headed off to bed.

The next day Izayoi and the others are given access to watch the match from the box seats alongside Sandora, Mandora and Shiroyasha. Sitting beside the small Demon Lord, Izayoi and Shiroyasha discuss the Gift placed on Black Rabbit's miniskirt and how not being able to see up her skirt can be considered an 'art', much to the chargin of everyone nearby. With the appearance of Ayesha Ignnus Fautus from the [Will-o-Wisp] community, Asuka excitedly points out Jack-o-Lantern to Izayoi. Watching the game, Izayoi noted that Yō doesn't possess the power to defeat an immortal foe like Jack.

Shortly after the game, Izayoi notices the black Geass Rolls and takes one in hand, reading the contents. Izayoi is blown off of the balcony during Shiroyasha's sealing, as per the rules of the game, though catches Asuka and lands safely on the ground. Once he does he sees the attacking demons in the distance and tells Jin to help the people in the area. Izayoi jumps towards the attackers and catches Wesser off guard. After dragging him up the wall Izayoi is trapped by Wesser's power, but shows no sign of worry as he began to explain the riddle regarding the Geass Roll. His response inpresses the demon but Wesser makes the correction about him being the demon lord, explaining to Izayoi he was a low level demon. Eager to fight, Izayoi launches himself at the demon. Later Izayoi heard the flute of Rattenfanger.

Before a winner could be decided, the game was cancelled by Black Rabbit's [Judge Master], forcing both sides main players to attend a meeting to negotiate the game. Izayoi joined as a representative for the [No Names] alongside Jin. Izayoi then asked Mandora about how the game would be handled. The Little Garden Central Network confrimed there was no misconduct within the game, allowing one of the demons to ask about the game being pushed back a month. Izayoi and Jin spoke up in refusal, Jin then explaining whom the demom, Black Percher was. Pest then went on to threaten the safety of the communities that were exposed to her patheogen, in which case Izayoi negotiates the recurrence of the Gift Game on an earlier set date, even adding Black Rabbit to the participant and prize list. Pest agrees following Jin's words and the game resumes in seven days.

During the period Izayoi had watched over the sick Yo while also studying up on the Pied Pier of Hamlin tale. He began to exlain to her the Parallel World Intersection theory Black Rabbit spoke of when they arrived and how it ties to the Gift Game and the tale. He deduced that the key to winning the game is by looking at the stained glass panels reciting the tale, and the reason Shiroyasha was sealed was because of the sun entering a cool period during the Black Plague. Izayoi thanked Yo for helping him solve the riddle, concluding that the group is from the Grimm's fairy tale and not the real Hamlin event.

When the game resumes Izayoi initially joined the town to destroy the panels but then the town of Halmin was summoned, replacing the city as a whole. Izayoi ends up being attacked by Wesser, who wasgranted [Divinity] and thus able to harm Izayoi. Their fight continued until Izayoi revealed Wesser to be the real Pied Piper of Hamlin, the true cause of the death of the children. Wesser, suprised by the boy's sharpness, invited IZayoi to join his community. Izayoi declined, saying he had a goal to work towards. He goaded Wesser intousing his most powerful move, the explosion leaving Izayoi's arm broken and Wesser's weapon destroyed. With the item used to summon him gone, Weser was unable to continue fighting and faded away, leaving Izayoi victorious.

Izayoi raced over to the battle with Pest and saved Black Rabbit from Pest's attack. He continued to fight until Black Rabbit activated her gift of [Chandral Mahal] to transport everyone to the moon. Izayoi mentioned the loss of Pest's power since she was away from the Grimoire she activated, he participated in a combined effort to defeat her and watched as the Spear of Indra thrown by Deen killed the Demon Lord.

Returning to the North Side, Izayoi confronted Mandora in his office and confessed to knowing about [Salamandra] staging the entire event, including the Demon Lord attack to show off Sandora's worth. While he did threaten to destroy the community and Sandora included if his friends were killed, Izayoi lets Mandora go once the man refealed the entire community but Sandora knew of the plan and offered his life so long as his comrades were spared. Izayoi let him off on the condition [Salamandra] come to help them when needed.

At the [No Names] farmland, Izayoi learned the fairy Merun could not revive the soil, and so offered a solution of using fertilizer to help revive the land. After learning she could, he ends up watching the [No Names] work together on the land.

Volume 3
Because of the [No Names] participation in defeating the Demon Lord, they received a VIP invitation to the Underwood Harvest Festival. Izayoi and the others were excited to join, but due to the length of the festival, it was decided by Jin that one of them had to stay behind and switch places with another during the festival, meaning only one would be able to enjoy the festival to its fullest. To decide who would go, Izayoi made the suggestion of a competition where they participate in as many gift games and win prizes that would help out the community. The one who produced the most results and possibility to get more prizes during the Harvest Festival would get to stay the longest. The plan was easily accepted by the others.

However, due to Izayoi's exploits and rumors of his power, he was not able to participate in many Gift Games as no one would invite someone who was sure to win the game. This forced him to turn to Shiroyasha for assistance. A few days later, Izayoi challenged the Water God that he defeated before, on advice from Shiroyasha, to a gift game. During the game he learns the water god is actually a goddess, Shirayuki-hime. Although the game was difficult for him to solve at first, he manged to solve the riddle of making the Aqua Fran bloom and won the game. By doing so, he won Shirayuki-hime's servitude and was forced to becoming the second maid of the No Names.

Shortly afterwards Izayoi returns to the community grounds to find Asuka destroying the ruins with Deen. After chiding her they made their way to the community grounds, picking up You and Lily along the way. Izayoi learned about the exploits of Asuka and You, and decided to bring everyone to [Thousand Eyes] to show off his results. After a quick banter with the Shopkeeper, Izayoi entered to see Black Rabbit and Shirayuki-hime attacking Shiroyasha. Afterwards, the group settled down and began discussing why Izayoi challenged Shirayuki-hime.

By winning ownership of her Izayoi was able to loan her to Shiroyasha, who had plans on developing the Eastern Lower Floors, but to do that she needed a water source. Izayoi challenged Shirayuki-hime to obtain that source so that it wouldn't appear that Shiroyasha was showing favoritism, and in exchange earned a [Consession Grant]. As such Izayoi won the chance to stay at the Harvest Festival for the entire time. After the party Izayoi joined Lily and Leticia in the bath. After washing Lily's hair and ears, he conversed with Leticia regarding the origin of her last name, vampire heritage and dragons. After the bath Izayoi checked his basket to find his headphones had disappeared.

Izayoi allows You to take his place at the [Underwood] Harvest Festival, opting to find his headphones. Later at the farmlands he spoke with Lily and learns about her ancestry and how her mother was taken. Izayoi decided to appeal to Lily's God to find out where her mother was after the Harvest Festival. Leticia continued to express interest in Izayoi's past and he obliged to her curiosity. Afterwards Izayoi ends up hearing about the attack on [Underwood] and heads there with Leticia. He talks with Black Rabbit and remarks on the beauty of [Underwood], the culprit who took his headphones, and how he plans on making the No Name Community so big that the old members will even hear about it.

Black Rabbit talks to Izayoi and hopes to introduce him to her benefactor. Izayoi remarks about the stars in the Altair losing their brightness. Izayoi soon discovered that the harp had something to do with the mysterious song. Soon after this a dragon appeared. He witnesses Leticia being kidnapped and heard her last words on how to clear the newly reinstated Gift Game before vanishing, "Defeat the thirteenth sun."

Volume 4
Izayoi attacks the Giants the minute they reappear and manages to push them back with ease. He manages to lift the spirits of the [Draco Grief] alliance and push them to keep attacking. The game was place on hold, but the dragon flapped its wings and lifted to the sky, carrying people along with it. Izayoi, Asuka and Black Rabbit discovered that You was at the castle in the sky after she went save some kids that were attacked by monsters (influence of the dragon). A meeting was going to be realized to see what to do about the game and Izayoi represented [No Name]s along with Asuka and Jin. During the meeting, Izayoi begins to suspect the creation of a [Demon Lord]s alliance.

Afterwards, Asuka asks him if she could join the search for You, to which he declined. However he decided to test her and see if Asuka could handle herself. Izayoi watched the battle between Pest and Asuka, which ended in the former's favor. When Pest went too far in making fun of Asuka, Izayoi took the opprotunity to punish her, by  dumping a bucket of water on Asuka, Pest and inadvertingly Sala. He scolds Pest for her actions and has both her, Asuka and Sala take a bath with each other. If Asuka and Pest refused, then he would bathe with them.

When the game begins once more Izayoi is at the front lines riding Gry up to reach the castle. Before he leaves Sala gives him the Grass Bracelet so he could communicate with Gry, and a trident to fight with. During the way he is forced to fight against Leticia's Shadow.

Izayoi activates his Gift's full power once more against the Huge Dragon of the Ophiuchus zodiac.

A Tea Gathering (Short Story)
Izayoi was sleeping in the dormitory room when You knocked on his door. He allowed her to enter and she apologized for the loss of his headphones. Izayoi let her go because she was not the one who stole them but respected how she took responsibility for Calico Cat's theft. Once Asuka arrived with tea and snacks, the three problem children sat down and began discussing about themselves and their time periods. Izayoi tells them about the time when he saw the dam near the Igazu falls, but didn't tell them the full story. Afterwards he showed doubt in You being from the future and asked about a popular trend in her time period. You's response of Rabbit Ear headphones caused both him and Asuka to laugh.

Lily's Big Adventure (Short Story)
During the clean up from the demon lord gift game Izayoi was found helping the other cook, startling Lily as she found that Izayoi doing chores was unfair. Izayoi understood her culture shock and explained that back on his world it was a normal thing for him to do as he came from a facility that rotated the chores.

Lily told him and several others about the shop she went to, to which Sala, Izayoi and the two other problem children showed interest in going to. After arriving, they find a geass roll depicting a supposedly impossible gift game. They encounter several moving dolls who appeared to be oily buff men, to which the women felt disgusted but he felt interested. The left the shop after being chased after by the dolls.

He then encounters Coppelia, brought by Lily, being chased by a [Last Embryo] [Demon Lord] called End Emptiness. He agrees with Lily to finish the gift game of creating a Perpetual Motion Machine, which he accomplishes using a fragment of Deen.

The demon lord was then banished after having completed the gift game. Later on Izayoi joined a banquet celebration where he showed off his cooking skills to the group and developed on the dish he served earlier. However the strong men dolls attacked once more. Izayoi decided to start a new game to destroy the dolls, throwing a frightened Asuka and You towards them.

Volume 5
Izayoi decided to rest in the Library and read while Asuka and You participated in the Gift Games. When black Rabbit found him and commented on the glasses he wore, he explains that they were bought from Jack to help him read better in the dark. He meets Kouryuu and immediatly insults him.

Volume 7
Izayoi fights “His Highness”

Volume 8
Izayoi has a hard time fighting Azi Dahaka

Gifts
Code: Unknown - Not much is known about his ability as the Gift Card, a fragment of Laplace, could not categorize his ability and so named it Unknown. Despite this, he seems to know his power well, being able to gauge whether or not he can take an opponent on. He can defeat those blessed with Divinity such as a water god and Wesser, deflect a lance attack from the weakened Leticia, stop a sword attack from the Perseus leader with one finger and defeat the Kraken and Graea. According to Jin and hinted by Black Percher, he can not only cancel gifts, but destroy them. Black Rabbit even stated he has the gift to destroy the heavens and the earth, and later with a statement by Baron even destroy the stars. This is shown during his battle with Algol and Black Percher, where he easily deflected their attacks. The force he emits behind his strength and speed is described in the Light Novels to be the Third Cosmic Velocity.

Canaria stated that if his gift were to be given a name, it would be [Last Future of Embryo].
 * Enhanced Strength: This seems to be the main function of Izayoi's Gift as it grants him immense strength. He uses his strength to throw objects at the 'Third Cosmic Velocity', run on walls by digging his feet into them, and even compressed Leticia's lance into a ball by simply punching it. His full strength is best seen in Volume 6 duirng his fight with His Highness. The battle was described as something that shattered the area around the colosseum and continued all the way to the walls, most of the damage done by Izayoi.
 * Enhanced Perception: Izayoi possesses an exceptional sixth sense, easily signaled out Fores Garo's henchman in Episode 3 and Leticia's prescence when she was hiding outside the window in Episode 4.
 * Enhanced Speed: His speed is said to be on par with Black Rabbit, who is mentioned to be part of the fastest species in Little Garden. However, his speed is different from hers as he is able to retain that speed as shown when he blocked an attack meant for Black Rabbit, returned her safely to a rooftop and proceeded to return to fight Black Percher.
 * Enhanced Durability: Izayoi has been shown to be rather durable, being the only one out of the three problem children to not need a Gift of Protection to survive his fights and take on powerful attacks without being injured. It took Wesser with double his power and popssessing [Divinity] to even injure Izayoi and even then the injury did not slow Izayoi down. In his battle with Azi Dahaka, Izayoi was stabbed through and suffering from grevious wounds but remained able to fight the Demon Lord.
 * Aurora Pillar - A power that revolves around creating a light construct in the shape of a small pillar which then enlarges to the point of reaching sky; he then swings it at his enemy. This is the true manifestation of Izayoi's power to destroy Gifts. He has used it only three times: to destroy pocket dimension, to destroy strong species and in his fight against Azi Dahaka - their clash reduced Volcano to nothing more than subatomic particles. Highness described it as a "Another Cosmology", a secret of Gods to construct their "universe".

Grass Bracelet - A bracelet made of grass. It gives the owner the ability to talk to griffins. Sala gave this to Izayoi to let him communicate with Gry.

Natural Abilities
Keen Intellect: Izayoi is incredibly intelligent. He had created plans to help the No Names in both battle and commerce. Izayoi has shown that he is knowledgeable in both religions, fairy tales and mythologies, having easily identified the [Perseus] artifacts, the story of the Pied Piper of Hamlin, and identifying constellations and asterims. Its been stated by Asuka that without Izayoi the community couldn't come up with a plan of attack.

Hand-to-Hand Combatant: It has been stated that Izayoi is a very competent fighter and also has amazing reflexes and potential. Saurian Demon King remarked that Izayoi had the potential to be an experienced martial artist with his skills.
