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 at all times which also seemed to be his weakness for he was willing to do anything when his headphones were held as 'hostage'.

He wears a gray-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 with the same color and a pair of tennis shoes with black, white and gold tones.

In the later parts of the light novel, after his gakuran was made into makeshift bandages for Gry when the latter was injured and his headphones destroyed in the incident in Underwood, Izayoi's new set of clothing consists 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.

Personality
Izayoi Sakamaki, who’s bored of his everyday life, wanted at least something fun to do. He even claimed that if he could sell his boredom, he could make a living out of it. For that reason, he seems to love all kinds of games, and thus joined the Gift Games without hesitation. He appears to enjoy challenges, which is shown thus far in his desire to take on the demon lords. Very early on, when he first arrives at the Miniature Garden, he challenges a water god.

Judging by his actions, he is quite intelligent which is seen when he memorizes the order of the cards and coming up with a tactic for the other two to easily find one in the card game in Episode 1 and his gift gives him amazing strength seen when he defeats the water god with ease. Due to this, he finds most normal tasks fairly easy and boring to him. It is said that he was taught random trivia when he was younger, and it was Canaria who taught him the beauty of the world. This is the reason he is so knowledgeable about the Perseus community, and in Episode 7, the story of the Piper of Hameln.

He's also very arrogant and rude but knows when to back off as seen in Episode 2 as he did not continue to challenge Shiroyasha. He also takes pleasure in thinking perverted thoughts about Black Rabbit along with Shiroyasha.

As the story continues, it is also shown that he cares a lot for the Community and constantly make plans for the improving and building of its reputation.

Though seeming violent on the outside and self proclaimed hedonist, savage, vulgar and hopeless person, he is shown to forgive people who apologize sincerely very readily. He also feels protective when he learns that a criminal is targeting young children. He has a unique charisma that draws people to him and follow his lead.

However, because he knows how different he is from others, he feels that he has no one to depend on and thus often taking on all the burdens himself.

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. 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, almost like hide and seek. He would give prize money if someone found him before the time limit. If they failed to find him, he said he would probably go on a rampage because the world was too boring. He played these games to find someone on his level, as is shown when Canaria finds him.

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

A few years later he attended High School, intending for it to be a surprise for Canaria.

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 one responsible for the disappearances; the lawyer.

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 occurance. 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 abandon his family, his friends and his fortune and opens to read the invitation letter.

Volume 1
After receiving a letter, Izayoi arrives in Little Garden alongside Kudou Asuka and Kasukabe You. Naturally he conflicted with the two girls. He was the first to notice Black Rabbit's appearance and was similarly impresed by the fact that other girl was able to sense the presence of Black Rabbit as well. Izayoi took the initiative to charge forth, draing the fellow out of her hiding place. Only to be 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 travelled 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.

Gift
Code: Unknown - Not much is known about his ability of the gift card; a fragment of Laplace categorized his ability as Unknown. Despite this, he seems to know his power well, being able to gauge whether or not he can take an opponent on. It is shown that his ability grants him a boost in power and possibly perception (He was able to detect the Fores Garo operatives sneaking on the premises as well as Leticia whenever she was trying to hide her presence). Even his speed is increased greatly (equalling Black Rabbit's). He can defeat a water god with ease, 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, he can not only cancel gifts, but destroy them. According to Black Rabbit, he has the gift to destroy the heavens and the earth, and the power to destroy gifts simultaneously.

It was once hinted by Black Percher that his gift is able to destroy other gifts.

In volume 3, his ability was described as the ability to destroy stars when he talks about his life with Leticia.

Canaria stated that if his gift were to be given a name, it'd be 'Last Future of Embryo'.

Aurora Pillar - power that revolves around creating a light construct in the shape of 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".
