First Appearance
Anime Debut Episode 1 - The Problem Children Have Arrived at Hakoniwa, Haven't They?
Seiyū Iori Nomizu


A rabbit-eared girl who resides in the Miniature Garden. She's the one who summoned the problem children. She often tries to be serious but easily gets flustered and usually speaks in third-person. Her normally blue hair turns pink as she gains increased power.

She is a member of the community called "No Name". And the overall caretaker for the Community's children.

As stated from Episode 4, rabbits have the authority to judge and referee games. In order to participate in the games, they'd have to meet a number of requirements.

She has been called several names/titles. These include "Symbol of Selflessness", "Moon Rabbit", "Noble of Miniature Garden"

After the arrival of the problem kids, her titles continue to grow... [Highborn of Little Garden(lol)], [Highborn of Little Garden(deko)] and [Highborn of Little Garden(porn)] mostly named by Izayoi.

Black Rabbit is, possibly, the last Moon Rabbit after an attack by Azi Dakaha, When she was 10 she was to be given a name by her parents and named the 'heiress' of the Moon Rabbit tribe for being granted four of the ten divine gifts of the clan, being the fourth in the tribe's history to possess the Gifts. However, the attack changed this and Black Rabbit was saved by Canaria, Leticia, and the Lion of the Sun, and hit on by Baron La Croix.

After the fight in which the Demon Lord was sealed away, Black Rabbit was adopted a few days later by Canaria and brought into the community.


Black Rabbit has light blue, long hair with two bunny ears on top. Her hair turns pink when using great power, as shown in episode 1 as she chases Izayoi Sakamaki to the edge of the world. When her hair turns to a complete blood red, she has enough power to send Izayoi flying through several walls with a single hit. She has red eyes and wears a black/navy blue, red and white ruffled outfit which Shiroyasha recommended because she would earn more while refereeing a Gift Game. She also wears a black collar with white ruffles, a mini skirt with garters, red heels with white ruffles on top and wristbands/ cuffs that match the outfit on both of her wrists.


Based on her title "Symbol of Selflessness", she is willing to bring the No Names flag and title back, and other various things (like getting Leticia, their former demon lord leader, back for the community), Black Rabbit is a very loyal person. She will do whatever she can to help the people she considers friends, as well as the entire communities, even if it means sacrificing herself. However she does have some pride as the Noble of Miniature Garden. She gets flustered quite easily but still when she needs to be serious she is. Black Rabbit is really a considerate kind person but when angry she does get quite and scary and quite powerful. Black Rabbit also is a bit of a worrywart. She's always afraid someone would get into trouble and cause the whole community to have a bad reputation. But still she always trust her friends and believes in them, most of the time. As was shown in volume 5, she had doubts about entrusting Jin with a very important job.

Compared to others she had been shown to be very gullible against Izayoi.


Izayoi Sakamaki- Black Rabbit and Izayoi have a "Constant" relationship. Izayoi always has some "fun" with her like tickling her and pulling her ears. It also stated in Episode 5 that Izayoi and Black Rabbit were discussing about their flag of the No-Names. Izayoi said, "I want our flag to be in the stars." Black Rabbit replied, "Seems romantic," and they both smiled at each other.

Shiroyasha- They both seem to have a close friend relationship. Shiroyasha thinks that they're "more" than friends, so she does perverted actions towards Black Rabbit as shown when Shiroyasha jumped right into Black Rabbit's chest.

Canaria - After the destruction of the Moon Rabbit Community, Black Rabbit was adopted by Canaria.

Leticia Draculair- Black Rabbit treats her like a royal

Jin Russell - Jin is like a little brother to her who she can not stop worrying about.

Asuka and You - Both of them love to tease and play with KuroUsagi


Black Rabbit summoned the trio to Little Garden. The first impression that she gave, however, only seemed to be that she is cosplaying; Black Rabbit tried to be serious about what she planned on saying, but initially, the trio did not take her seriously.

Eventually they listened and she revealed the reason she summoned them was because of their gifts. While hiding the true goal for their summoning, she explained to them the Gift Games and started one to better explain the purpose and how the games work. All three of the humans were able to pass the game using a trick that made Black Rabbit feel devastated.

She brought Asuka and Yo to the outer gates, but was forced to travel to the Edge of the World to find Izayoi, who had left during the trip. Upon spotting him, she witnessed the defeat the Water God by the boy and the Water Tree that he had rightfully won from the challenge. The water tree was a Gift that really made her excited as it now meant that her community could have their very own source of water and did not have to travel long distances to fetch it from other Communities or rivers. However, her excitement only act as a further confirmation for Izayoi's doubt about the true reason behind the reason for them to be summoned and he confronted her about it.

Black Rabbit realising that the secret couldn't be kept in the dark any longer, had spilt the secret about the Community's current situation to him. Of which to her relief, he had agreed to stay as their comrade though she had pushed his words of descibing it as 'More interesting that way' kind of nagged at the edge of her mind away with her happiness.

Later in the day Black Rabbit was forced to accept the fact Asuka and You entered a Gift Game that was to occur the next day. She smacked them both with a paper fan in retaliation for their rash actions, but relented and allowed them to go through with the game once she realized she wasn't going to win against them. With the decision to get the problem children appraised, Black Rabbit took everyone, including Jin Russell, to Thousand Eyes, and there sexually harassed by her old friend, Shiroyasha.

While there Black Rabbit explains to the Problem Children about the gates of Little Garden and the Floor Master's responsibility to protect the district they are assigned to. She then bears witness to a Gift Game between the Problem Children and Shiroyasha after they challenge her to one. Black rabbit was shocked that You would bet her life in the game if she was unable to ride the Griffon. She was happy as she watched You not only wn the Gift Game but also aquire the powers of a Griffon.

The group returned to the No Name Community grounds after the Gift Game, Black Rabbit planting the water tree and refulling the grounds. Shortly afterwards, Black took a bath with Asuka and You, talking about the next days Gift Game against Fores Garo and various other stuff that she refers to as 'Girl Talk.'

During the Next Day she was to remain outside the grounds and had to rely on her ears to refree the game as the Geas Roll did not state she could enter the grounds, to which Izayoi calls her out for being useless, causing her slight grief. Once the game was finished, she grew concerned for the wound You sustained and spirited her away back to the No Name Community to use several healing gifts to help the girl.

Later that night, Black Rabbit is reunited with her mentor/friend, Leticia, and is appaled to hear her Gift Game had been cancelled, and the reason she even returned was to ask for Jin to disband the community, something that is impossible to due at the current stage. Black Rabbit watched Leticia test Izayoi, and saved her when the crushed lanced was thrown back at her. Black Rabbit recovers the vampire's Gift Card and learns that all of her Divinity vanished, upset that this could even occur and even asked Leticia how it happened.

The talk was cut short as those from the community Perseus were sent to recover Leticia, doing so by using the Gordon's Gaze to imprison the vampire in stone. Black Rabbit tried to converse with htem, but was quick to anger once a member insulted her community. Revealing one of her gifts, the Spear of Indra, she intended to fight the members of Perseus but was halted by Izayoi tugging her ears. The members of Perseus vansihed, forcing Black Rabbit, Izayoi and Asuka to confront the leader, Lauis, at Thousand Eyes office.

Laius took an interest in Black Rabbit and tried to get her to transfer to his community, this sparked Asuka and Izayoi to remark that her legs belong to them, with Shiroyasha getitng into the act, ending with Black Rabbit smacking Izayoi with her signature paper fan. The conversation, when it was serious, took a turn for the worse with Black Rabbit contemplating trading herself for Leticia's freedom when she was offered the chance, something Asuka was against.

In order to obtain Leticia's freedom and prevent Black Rabbit from sacrificing herself, she proposed the legendary gift game Perseus would conduct, but declared it would take years to accomplish. Izayoi appears and reveals he completed the game, and Black Rabbit traveled to the Perseus Community, announcing that they are to participate in a Gift Game when she reveals the two treasures won from the Kraken and Gorgon.

As Judge Master Black Rabbit is to refree the battle while everyone fights their way to the arena. Before the start of the game Black Rabbit was surprised at Izayoi's knowledge given how he portrayed himself for most of the time. During the game she grew worried for everyone's sake, but was quickly changed as she was assaulted by an invisible Izayoi tickling her sides. She respondede in her usual way: a paper fan attack.

When the mention of Laius not being the one to fight Izayoi, Black Rabbit feared the worst and those fears were confirmed when Algol was summoned. She was there to witness Izayoi dominate the fight, and when he smashed a beam that could petrify the world, she was flabberghasted, commenting that his gift can not only shatter Hevan and Earth but also the Stars. She announced the No Names as the winners once Algol was defeated.

Once Leticia woke from her petrified state, Black Rabbit was the first to great her, and the first to be shocked at the vampire's willingness to be a maid for the Problem Children. The thought left her just as quickly as she decided to throw a party outside. The reason for this was because the Perseus flag would be removed form the sky. During the time when the stars fell, Black Rabbit talked with izayoi, which ended with the Problem Child declaring to place their flag in the sky, something that Black Rabbit agrees whoeheartidly with.

Volume 2

One day Black Rabbit received and hid an invitation letter for the 'Rise of the Fire Dragon' Festival that was to take place in the North, but the Problem Children found it and as punishment left a letter claiming to leave the Community if KuroUsagi did not find them by sunset. The letter caused her to enter enraged mode(pink hair) and after looking around the community grounds, she head off into town, completely angered and upset with the children for what they said in the letter.

She tracked them down by using an Astral Gate, which usually required a toll to be used, for free as she's an Aristocrat of Little Garden. First to be caught was Yo whom she entrusted to Shiroyasha to look after. She then proceeded to hunt down Asuka and Izayoi, only to find them discussing about a Gift Game they dreamt of hosting when the farmlands were restored. Thanks to Leticia, a captured Asuka was left in her care, leaving Black Rabbit to solely focus on chasing down Izayoi.

She matched his speed and manages to get him to settle down long enough for him to issue a Gift Game, one where if she won it would give her the right to ask of Izayoi to do anything that she asked of him, albeit only once. He refused the terms, saying that he didn't want to participate if the terms were not equal and so offered the same condition should she lose. Once the terms were finalised and accepted, the Gift Game began with Kuro Usagi taking the first move, deciding to try and escape form his field of vision to better utilize her enhanced sense of hearing to catch him later. Izayoi's speed was on par with hers and she had to block various times to make sure Izayoi couldn't grab her. Just when Black Rabbit thought she would win, Izayoi decides to shatter the top of a building to trap her. The rest of the building bega nto tumble over, forcing both of them to destroy it. Through the collapsing rubble, both take hold of the other, and the Gift Game ends in a draw. Their antics however had drawn the attention of the Salamandra Military Poclice, forcing both to be taken into custody.

Once they have been, Black Rabbit was alerted to the real reason why the No Names were given the invitation, to help Thousand Eyes and Salamandra prevent the rise of a new Demon Lord. Black Rabbit and the No Names offered their help with enthusiasm. Later that day, Black Rabbit joined Asuka in the baths owned by Thousand Eyes, worried for the girl's safety. However Black Rabbit still had to endure Shiroyasha's perverse antics, as well as Izayoi's once she exit the bath. Even during the important meeting the Rabbit had to deal with the twos antics and desires to see her in different clothing.

During the meeting, Black Rabbit accepted Shiroyasha's proposal of being Referee at the Gift Game "Duel of the Creators" the next day, and was shocked to learn that possibly members of Grim Grimoire were still active and might be behind the soon to be attack by the new Demon Lord.

The day came and Black Rabbit acted as the judge for the Gift Game that was between You and those of the Community Will-o-Wisp, Ayesha and Jack-O-Lantern, declaring the winners of the game to be the latter. Aterwards, she congratulated Yu, but it was at that moment that black Geas Rolls fell onto the city. Black Rabbit realized the Demon Lords began their assault, confriming Izayoi's suspicions. As part of her job, she helped try and calm the citizens down, directing them out of the Colosseum. At the start of Ratten's song, she was not in th colosseum, but You and Jin directed wat Shiroyasha told them to say to her. This allowed Black Rabbit to halt the game with her Judge Master gift and declare a meeting between participating communities. During the meeting she confirmed the suspicions of the pariticipating communities, and that the Mao Community, Grim Grimoire Hamlin did not go against any protocals or conduct any wrong doing. However, the negotioations ended with the game to restart in a week and Black Rabbit to participate in the game.

Black Rabbit, along with Sandra, took on Pest once the games began, and revealed how Pest got her divinity, saying Izayoi was the one who told her. Black Rabbit and Sandra are barely able to hold their battle agains her until Pest activates her power, spreading a wind that will instantly kill anyone who breathes it in. Black Rabbit rushed to save a child and You, but the timly arrival of Asuka and Deen saved them and Black Rabbit needed to be saved by Izayoi. Black Rabbit conducts a plan that requires Izayoi to hold Pest back as she prepares to teleport everyone to the moon.

Once there Black Rabbit activates the Sun Armor from her gift Card, the Gift canceling Pest's powers, allowing Sandra to hold her in place and Asuka to use Deen to throw the Spear of Indra at Pest. The hit destroys the Mao and the battle is won.

Once back at the No Name land, Black Rabbit assisted the kids of the community and helps them out at rejuvenating the farm.

When things took a turn for the worst, Kuro Usagi was requested by his Highness to materialize her Sun Armor for him to test his strength. The Sun Armor was easily destroyed with a punch and Kuro Usagi left very badly injured.

Volume 7

Though she managed to recover from her wound, her powers as a Moon rabbit seemed to have vanished and so did her other Game judge powers: her rabbit ears, turning her into a normal girl. This was due to the fact she had broken a rule concerning her Gifts; She must never use the Spear of Indra at the same time as the Sun Armor.
