Yō is a petite young girl with short brown hair that she keeps back with a hair clip. She usually wears an open white and blue jacket, that is ankle-length and splits into two ends past her thighs. She also wears a white blouse underneath and a pair of orange pumpkin shorts, as well as black knee-high socks and tall brown boots. A blue band is wrapped twice around her wrists and around her neck is her Gift Genome Tree which she got from her father. The wood carving is attached to a black band necklace.
When utilizing her Gift's true power, the wood carving changes into an item or piece of armor for Yō to utilize.
Pegasus Boots: Her wood carving transforms and forms into silver, armor boots with wings adorn on them.
Introverted and laconic, Yō is a very quiet and introverted girl, preferring the company of her many animal friends than actual people. Before arriving in Little Garden, she had yet to make a human friend, and as a result her friendship with the [No Names] is very precious to her. Despite her quiet nature, Yō is anything but shy and approaches most situations, both dangerous and mundane, with confidence, as well as showing great curiosity towards the world. Though she is driven to prove her worth and help her friends, Yō still struggles to accept help in return, as shown by her reluctance to take a partner into her Gift Game against Ayesha and Jack, a trait the latter was able to notice.
Yō's personality takes from her father who used to be laconic and caring to his comrades. She is friendly, despite showing little emotions other than times when she's hungry or satiated, and fiercely protective of her friends. Yō is also a bright young girl and a fast learner, being able to copy and utilize Izayoi's techniques of solving the riddles in the Gift Games, as seen in volume 4. Also, she was able to figure out the legend regarding the will-o-wisps and their connection to the community with the same name as well as being knowledgeable in how the phylogenetic tree works. Her intelligence is shown to be possibly on the same level as Izayoi. During her time in Little Garden she begins to show an improvement in both her way of thinking and in her own self esteem, growing more confident with herself.
Yō was bedridden for most of her life due to a weak physical constitution. However, she was frequently visited by her father, who told her stories of his travels. One day he gave her the gift [Genome Tree] which granted her the ability to talk to animals and take on their traits. This gave her the ability to finally walk and interact with society. However, the friends she made did not believe her when she told them of her ability to speak to animals or even of the exploits of her father such as the Gryphon story and she gradually redrew further into the animal kingdom for her friends.
Her father promised her that they would go on an adventure shortly after she was released from the hospital. But on the date he promised, which was two years later, he never came to pick her up.
In volume 10 it was revealed that only due to her fathers massive spiritual power she was able to be born. Since her mother was from Dystopia and had little to no spiritual power it resulted in Yō's weak constitution. Since her mother was from Dystopia it allowed her to gain a gift that allowed her to use the [Genome Tree] freely without turning into a Chimera.
Yō arrived alongside Izayoi and Asuka in the world of Little Garden, being summoned by a letter sent by Black Rabbit. She introduced herself to the others while drying Calico Cat's fur with a cloth. Shortly after Izayoi and Asuka revealed they noticed a person hiding from them, Yō revealed that she could smell the person. Once Black Rabbit was driven out from her hiding spot by Izayoi, Yō was the second to chase after her, hoping from one tree to the next with incredible acrobatic skills. Once she realized the girl was a rabbit, Yō pulled on one of the ears to sate her curiosity, her actions followed by the other two.
Black Rabbit introduced herself and began explaining the world of Little Garden along with the Gift Games. When the explanations were finished, Yō was invited to play a small game, and while she developed a tactic to ensure her victory, it was unable to be practiced as Izayoi's method secured her and Asuka's victory. Excited about this new world, Yō followed the moon rabbit to the leader of her community. Though once it was revealed Izayoi went missing, Yō revealed that she noticed and decided not to say anything as it was too much of a bother.
Black Rabbit headed off after Izayoi, leaving Yō and Asuka with Jin Russell. Jin took them to a cafe where Yō reveals a small portion of her power; the ability to understand animals. Asuka's compliment was met with Yō questioning the other girl's power. Before Yō could get an answer they were interrupted by the appearance of Galdo Gasper. Then Yō and Asuka learned the truth regarding why they were summoned; because the community that summoned them was in need of help. Yō originally came to Little Garden to have friends, and by making one through Asuka, had decided to join the No Names and decline Galdo's offer to join his community. Yō stopped him from harming anyone, and agreed to participate in a gift game against [Fores Garo].
Yō follows the others to the [Thousand Eyes] shop and meets Shiroyasha. When she found out that Shiroyasha was the "Strongest Host", Yō wanted to challenge her. Shiroyasha summoned a Game Board representing the White Night, shocking Yō. In the end the girl decided to follow Izayoi's examples and let Shiroyasha test them. The moment the Gryphon appeared Yō was the first to try out the game. Yō introduced herself to the Gryphon named Gry, intriguing the beast a bit at how she spoke to him. Yō pitched the idea to the Gryphon; if she could not ride on him throughout the entire race then he was allowed to eat her. Amused by her proposal Gry let her participate in the game. Yō had difficulty staying on the Gryphon's back, but her determination to be friends with him got her through the game. Yō fell off of the Gryphon's back, but demonstrated the power she obtained from him. Shortly afterwards Yō was given a [Gift Card] to hold her Gifts.
The [No Name]s left the [Thousand Eyes] shop and traveled back to the HQ of the community. Yō was surprised by the grounds being so desolate. Yō was there when the Water Tree was placed on the pedestal and caused water to overflow in the canals. Later she joined Asuka and Black Rabbit in the Bath, Calico Cat with her as well. The three had a small chat until they left to get new clothes. Yō however, continued to wear the clothes that she had on when she first arrived.
The next day the [No Name]s traveled to the Residential District of [Fores Garo] to challenge Galdo. However, upon arriving they learned that the district was transformed into a jungle and that they had to use a specified Gift to defeat him. Yō went inside the district with Asuka and Jin, using her heightened sense of smell to locate Galdo within his manor. Upon entering the room he was located in, Yō was shocked to learn Galdo became a white tiger. She decided to fight the now demon tiger herself and bought time for Asuka and Jin to escape. Grabbing the silver cross sword that was embedded into the wall, Yō fought Galdo. Sadly she was unable to win and forced to retreat herself as she had taken a large wound on her arm. Yō found Asuka and Jin and ended up apologizing for not defeating him. Once she did she collapsed from the blood loss. After the game Black Rabbit took Yō back to the [No Name] headquarters.
Yō remained sleeping through the events with Leticia and the meeting with [Perseus], but awoke some time later to give cookies to the arguing Asuka and Black Rabbit. The cookies were baked by the children of the community and Yō was asked to deliver it to them. Yō discusses with Black Rabbit and Asuka about how to rescue Leticia, but upon realizing the only way to do so would take years, began brainstorming another way. The girls were interrupted by the arrival of Izayoi who delivered a special present to Black Rabbit; the Gifts that let the [No Name]s challenge [Perseus].
Yō was fit to join the game and was given the task of luring out the men wearing the [Helmet of Hades] which allowed for invisibility so that Izayoi and Jin could get the gifts. Originally she had difficult when a soldier wearing the original and not a copy joined the battle, but she was able to utilize Echolocation to give Izayoi, who was wearing a replica helmet, the chance to land a successful punch on the individual. Yō remained by herself to fight off the rest of the soldiers while Izayoi and Jin moved on to fight Laius. When Laius activated Algol, Yō became a victim of Algol's Petrification, thus turning to stone.
The [No Name]s won the battle and earned the rights to own Leticia. However the problem children decided that Leticia would be their maid. As justification Yō declared she was turned to stone for the vampire. Afterwards, the [No Name]s gathered outside to have a small victory party/welcoming party for Izayoi, Asuka and Yō. In the end Yō watched as the [Perseus] constellation was removed from the sky, marveling at the sight.
A certain normal day in Little Garden (Short Story)
Yō and Lily awoke Asuka to inform her about the letter from [Thousand Eyes], and shortly after went to locate Izayoi in the Library. The letter was an invite to [Salamandra]'s [Rise of the Fire Dragon] Festival. Originally Jin and Black Rabbit hid the letter but Yō found it and so the three problem children decide to go regardless of Jin's wishes. At the same time they leave a letter for Black Rabbit challenging her to a game; if they cannot find her before sunset then they will leave the community. Yō and the others arrived at the cafe and discussed the plans to get to the North Side, but became interested when she learned that the only means would be the Astral Gate as the Little Garden had the surface area of a star and thus was impossible to walk the distance. And without money they could not take the Gate, as such everyone went to Shiroyasha under the pretense of her being the one to send the letter asking for them, so she should be the one to take them.
The former [Demon Lord] explained about how [Salamandra] was shifting power to a new leader, hence the reason for the festival. Shiroyasha asked the [No Name]s to join the festival with her, but before she could go into specifics as to why, Yō stopped her and asked how long the explanation would take. At the eagerness of the Problem Children, Shiroyasha took the group to the North Side. Transporting everyone in the room to a connection Thousand Eye base in the North Side's city, the group enjoys the sight of the different culture momentarily before realizing Black Rabbit had caught up to them. Though Izayoi manages to escape with Asuka, Yō doesn't get away and is caught by the moon rabbit.
Yō and Shiroyasha spoke regarding Black Rabbit and the Gift game <<DUEL OF THE CREATORS>>. Shiroyasha explained that it was a gift game that took place during festivals where Creation-Type gifts like [Genome Tree] are displayed during games. Yō decides to enter, and even asks if the Gift that is offered as the winning prize would be enough to make amends with Black Rabbit. Shiroyasha confirms it will be.
Yō defeats a Stonewall giant manipulated by the [Rock Eater] community, thus advancing to the finals. Later on in the day Yō joined Asuka, Shiroyasha and Black Rabbit in the [Thousand Eyes] hot spring before joining Izayoi and Jin for a meeting regarding the game. Yō asked about her opponents in the finals, but was told that she could only learn the names of those participating, those being [Will-o-Wisp] and [Rattenfanger]. This caused a shift to the conversation regarding the Pied Piper of Hamlin and the possibility of the [Demon Lord] prophesied to be part of a certain community that was defeated.
The next day Yō was matched up against the [Will-o-Wisp]'s community members, Ayesha and Jack-O-Lantern. Being transported into the game's stage by Shiroyasha, Yō and the others listen as Black Rabbit explained that the game will be <<Underwood Maze>>, with the goal being to escape the enormous tree or destroy the opponent's Gift. Yō took the initiative and was able to locate the exit rather quickly due to her keen senses that surpassed normal humans. However, she did not make it due to Jack ostracizing her way. Yō learned from Jack regarding the true purpose of revealing the Will-o-Wisp's as a scientific phenomena and as to Ayesha's true identity. Jack introduced himself as the immortal demon created by the demon who exists between the planes of life and death, and Yō realized she couldn't defeat him. As such she surrendered, causing the Game Stage to break. Even so, Jack spoke to Yō regarding why it was she quit the game. Yō learns from Jack what it meant to be part of a community and that she would have to rely on her comrades, the same way that they could rely on her. Yō is congratulated on her performance by Black Rabbit, Leticia and Jin.
At that moment, Black Geass Rolls fell from the sky, signaling the arrival of the Demon Lord. Yō decided to remain in the stadium with Asuka and Jin to talk with the now sealed Shiroyasha. Despite her attempt to explain the cause of her seal, Ratten appeared and had several [Salamandra] troops attack the group. Yō was able to blow them away, but succumbed to Ratten's flute due to her acute sense of hearing. The melody caused Yō to fall unconscious for a bit, forcing Asuka to order Jin with her Gift to take Yō and run. Shortly after the [Trial of Jurisdiction] was invoked, causing the game to be haled and go on a suspension period.
Yō eventually awoke and began helping the injured members of [Salamandra] alongside Rin during the meeting between the representatives of the communities involved in the game. Yō spoke with Ayesha regarding the missing Asuka. Yō ends up succumbing to the Black Plague pathogen released thanks to Black Percher and is left bedridden. Izayoi visits her a day before the game resumes and talks with her. Through their conversation, Izayoi is able to deduce the meaning behind the game and thanks Yō for her help, the girl smiling and wishing Izayoi luck.
The game resumed and Yō decided to participate despite her condition. When a child was in the way of Black Percher's winds, Yō attempted to save the child, only to end up being saved by Asuka and Deen. Yō was placed inside one of the houses with the child to be protected, and remained there for the duration of the game. With the death of Black Percher, Yō was cured from the disease and regained her health.
After the festival, Yō returned to the [No Name]s community grounds and assisted in helping the children revive the farmland.
Finding the answer to the Golden Plate Mystery
Candle, Omelette Cake and Ghost Town
The [No Names] were given a letter inviting them to [Underwood] to participate in the Harvest Festival as VIP's for their involvement in the defeat of the [Grim Grimoire Hamlin]. The conversation took a turn in which it was theorized a "Rabbit-Eating" plant might exist in the Mandragora species, to which Black Rabbit furiously dismissed much to Yō's displeasure. When it was decided that not all of the main force could go, it became a game where one of the Problem Children could enjoy the entire festival but the two would swap places from one enjoying the beginning and one the end of the festival. Yō wanted to go for the chance to meet the many Eudemons in the South, and thus make more friends like Gry.
Asuka, Izayoi and Yō return to the [No Name]s residence to give out the results of the game. Yō was able to win a game against [Will-o-Wisp], the Gift being a Candlestick that could create fire, thus providing a source of heat and light for the community.
However the group then moved to [Thousand Eyes] to obtain Izayoi's reward, in the process witnessing Black Rabbit and Shirayuki in rather short kimonos pulverizing Shiroyasha. Shiroyasha revealed that Izayoi was helping her develop the East Side and lent her Shirayuki for that extent. As a result Shiroyasha gave the [No Name]s the Concession Grant, giving them access to the Astral Gate for free as well as the right to receive 80% of the payed usage fees for the Astral Gate, promotion of their community's activities, the ability to decorate the Gates as much as they wish, and the title of [Region Master]. With this and the securing of a permanent Water Source, Izayoi had effectively won the competition. Asuka was allowed to attend the beginning of the Festival but would swap with Yō for the end of it.
After the celebration party, Yō mused over the accomplishments of her friends while looking at her own shortcomings. She felt sad for being unable to provide the saplings for the farmland and began to begin feeling that she cannot maintain the support in the relationship between the three problem children.
The next day Black Rabbit, Jin, and Asuka, awaited for Izayoi to arrive. However Izayoi revealed that Yō would be going in his place while he stayed behind to search for his headphones. Yō eagerly took his place and thanked him while promising to uphold her end of the bargain, that being to meet as many Eudemons in the South as possible. The small group representing the [No Name]s traveled to the Astral Gate. The first thing the group decided on doing upon arrival was going to meet with the Draco Greif Alliance and the spirits of the divine tree of [Underwood] as a token of thanks for the invitation.
Upon arriving the group marveled at the sight of the large Water Tree. Yō immediately spotted the perytons and before Jin could answer her questions, the group was welcomed by Gry. Gry assisted the group in getting to the city, along the way complementing Yo about her skills in keeping up with him at half his speed. Gry also answered Yō's questions regarding the Perytons, with Black Rabbit offering more information. Once Gry dropped the [No Name]s off, the group then reunited with Ayesha and Jack. The two explained about the Gift Game <<HIPPOCAMP RIDERS>> and challenged the [No Name]s to the race, in which the girls agreed to. In the end they went together to meet with the “Host” of this Festival and the person who was the savior after the disaster at Underwood. Along the way they traveled through [Underwood], Asuka and Ayesha scolding Yō for her mean joke.
They met with the Dryad named Kirino who wanted to thank the "No Name" for saving her little brother's life. Then the [No Name]s discovered that the leader of the alliance was Sala Doltrake, the older sister of Mandora and Sandora. Sala thanked the group for for what they did at the [Rise of the Fire Dragon Festival]. Yō admired Sala for her dragon horns which lead to a conversation regarding the communities in [Underwood]. When it was revealed there was indeed a Back Rabbit Eating Tentacle Plant, Black Rabbit grabbed Yō and the others and took off to destroy it. At the dormitory Black Rabbit told Asuka and Yo why it was she was excited to see [Underwood] and sub sequentially learned that Black Rabbit lost her homeland twice in her lifetime.
Yō returned to her room and found Izayoi's headphones in her bag. Black Rabbit arrived to tell her of an attack, but before she could ask about the headphones the two girls were assaulted by a titan. When Asuka joined, Black Rabbit asked Yō to take herself and Asuka away from the battle as the Moon Rabbit fight the Titan. Yō agreed and took Asuka to the surface, where the girls noticed the multiple battles across the area. Yō was ordered by Asuka to take her to a place on the battlefield and Yō did just that. Yō marveled as Deen was able to take on several Titans, but at the sound of a harp Yō noticed the Titans were heading towards her. Yō tried to reach her but a mist developed and blocked Yō's line of sight. Yō and the Gryphons were able to dispel the mist together and the girls reunited as Yō hugged Asuka. At that moment Yō learned that a female knight saved Asuka. Shortly after the knight's appearance, the battle ended and the Titans retreated.
Yō recalled about Izayoi's headphones and hurriedly returned to the dorm. When she arrived the girl found that the headphones were destroyed. Asuka found Yō cradling the pieces and before Yō could explain, a wooden beam collapsed, knocking Yō out. However the girl woke up at the medical tents made after the battle. Asuka spoke with Yō regarding the headphones, with Yō promising she did not know. Though Asuka confused her a bit, it was Asuka who suggested a person other than Yō who would steal the headphones. By utilizing her keen senses, Yō was able to determine the perpetrator, Calico Cat. The cat apologized to Yō saying he only did it because she was upset. Yō was his friend and so sought to take responsibility by repairing the headphones.
While trying to come up with a way to restore the headphones, Jack revealed he told Black Rabbit and Jin about the matter regarding the [Will-o-Wisp] game Yō participated in. In truth Asuka helped her with that victory, but both kept it a secret. Before the conversation could carry on, news reached the group that the Titans had returned for another assault. Yō was the first to arrive outside and heard the tune of a harp, similar to one played when the fog appeared. Yō learned from Gry that the female knight from before has entered the front lines, a harp that could slowly control a person's conscious was in effect, and [One Horn] and [Five Claws] were nearly destroyed. Jin's sudden remark caught Yō off guard, as he had declared that he would handle the situation. However, Jin asked Yō that during the distraction they made, she was the one who would steal the harp from the person using it. Yō positioned herself high above the clouds and Water Tree so she could escape the melody of the sound as well as position herself for a sneak attack. Thanks to the battle, Yō was able to pinpoint the controller of the harp and launched herself towards the person and steal the harp successfully, thus ending the battle.
The next day Yō was introduced to Faceless, the female knight that stopped the Titans. Jack spoke with her and she offered her assistance in Yō's plan to recover Izayoi's headphones. As Yō's father had a pair of them ,she intended to give the pair to Izayoi. The plan was to resummon Yō to Little Garden but with an imprint in her mind to wear her father's earphones. Yō spent half a day thinking of the headphones as per the requests of the summoning ceremony. During it though, Yō had lingering doubts that it was the right choice to come to Little Garden, and her past self began to feel the same way due to the ceremony. In the end though Yō decided that it was indeed the right decision to come, and her past self opened the letter.
The ceremony ended, and Yō was immediately hugged by Asuka. The reason was because of the headphones being cat ear headphones, to which Yō was shocked as it shouldn't have been possible. Faceless noticed something odd about Yō's Gift and asked Yō if she could see the Genome Tree. Yō learned from Faceless that her Gift wasn't just absorbing the power of animals, and sited it as the reason the ritual failed. Realizing her one attempt to apologize to Izayoi was thwarted, Yō dejectedly returned to her room.
Kasukabe Yō woke up due to a dream about her past. While thinking about it the sound of a harp played in the [Underwood]. Yō was forced outside due to the sudden attacks outside. She quickly recovered herself and helped to save Kirino, the attendant that greeted the [No Name]s and [Will-o-Wisp]. Shortly after the announcement of the Titans attack reached Yō's ears and a Black Geass Roll announcing <<SUN SYNCHRONOUS ORBIT in VAMPIRE KING>> was found. Yō told Calico Cat to go to Asuka while she remained with Kirino and fought off several of the monsters that dropped from the sky. However, the Dragon's winds caused several people to fly into the citadel, including Yo.
At the castle in the sky, Yo regrouped and saved several children from the monsters within the castle walls.
