Hachiman Shin-Ha, or most commonly referred to as Hachi, is a rabbit born under the clan of Shin-Ha, located somewhere within Japan, and is known for his courageous acts of demon slaying. Also, he is the first carrier of the Rage Gene. His goal in life is to slay as many demons as he can while he hunts for the demonic dragon, Lord Araki, who was responsible for the destruction of his clan and for nearly killing Hachi when he was younger, causing him to gain mechanical parts.

A rather outgoing soul a majority of the time, at other times he is rather cold or ignorant, often with a no-hope style of personality. When in battle, he's dead serious and does not joke around, and can be extremely violent at times, due to being fuelled with rage and hatred for demonkind. His hate for demons and his persistance to fight is what has kept him going throughout his life, coming back from the grave several times just to keep on fighting and fulfill his goal of destroying the demon responsible for his clan's death.


Hachi stands at 160 centimetres in height, with blue hair that reaches his back. He has light blue fur covering his body, and a large fluffy chest, covered in blue tints the same colour as his hair. He is not very muscular, due to the fact that most of his body was either regrown or replaced with machinery, and he possesses a noticeable mechanical left arm, and a mechanical left eye which is indicated by the red iris and yellow pupil. He has a crescent-shaped red scar on his side, gained when he was younger. He has long floppy ears, like a normal rabbit, and possesses a short tail.

In clothes, Hachi usually only wears a pair of trousers, which can vary from dark blue to purple from time to time. He can also sometimes be seen wearing an old golden ring acting as a band in his hair, which would tie his ears in a sort of knot, although he hardly uses this anymore as he is no longer a Samurai trainee.


Early Life

Young Hachi

Hachi at a young age

Hachiman Shin-Ha was born to a wealthy Japanese clan warlord, Kenpachi, and a beautiful maiden who practiced magic, Kaede. Hachi was introduced to a world of riches and indulgence, for a time. After a few years, he saw his older brother, Chinokawa, for the first time. Chinokawa had a severe dislike for Hachi, ever since he heard of his birth. Kenpachi had wanted Chinokawa to become his cold, heartless and powerful weapon so that when he passes, his rightful heir shall take the throne. However, all this attention was focussed on Hachi, who didn't agree to this training but it was necessary if he still wanted a roof over his head. Hachi lived a life of luxury up until the age of 5, where he would begin his training to be Kenpachi's own Samurai elite. He was proclaimed the "Sword of Hachiman", named after the Shinto god of war that was worshipped by the members of the Shin-Ha Clan. While he underwent his rookie training from elder Samurai warriors, his brother Chinokawa became even angrier as each day passed, forcing him to bully his little brother. Such

treatment would make Hachi more accustomed to the hardships he would face from demons later on in his life.

At a young age, he met his cousin Kyofu, otherwise known as Savaric, who was working as a servant slave for Kenpachi, in order to earn money for his parents who lived on the opposite scale of the class system. Kyofu and Hachi quickly became friends and Hachi would spend a majority of his free time hanging out with Kyofu, training him to fight as well as learning himself. They would spend many years together until Hachi reached the age of 13, where Kenpachi decided that the rightful heir to the throne would be either Hachi or Kyofu. He ordered the two to fight each other, and the loser would have to be killed. The battle itself was a very emotional one, as Kyofu felt betrayed that Hachi would rather have his title as prince than his friendship with him, and Hachi felt he would be disowned and exiled if he refused the fight. Tears and blood were shed, but ultimately Hachi won the match, though just as he was about to deal the killing blow, Kyofu got away and ran into the nearby forest.

A few days later, Hachi would go wandering into the woods to try and find him, curious if he had died or not. However, instead of Kyofu, he encountered a large stone komainu statue, with jewel eyes. His interest got the better of him as he climbed the statue and accidentally pushed one of the eyes out, allowing the nearby cave to rumble and shake ferociously. Hachi had unknowingly awoken an ancient demonic entity; the Dragon Lord Araki.

The Dragon Lord claimed to be one of the 20 Hands of Destruction, the elite leaders of the evil forces of the Inferno Realm, and so Hachi decided to take it upon himself to seal him away again. Although, he was no match for the large dragon, who had cut Hachi clean in half diagonally, while also tearing out his left eye and arm, but Hachi had managed to lob off one of Araki's hands before he did so. This allowed his blood to mix with Araki's, and the result would be the powerful Rage Gene. Araki proceeded to then leave Hachi for dead and kill the members of his clan, as well as burning the village to a crisp.


Three days after the incident, Hachi woke up on an operating table, finding only his upper half of his body and his right arm were saved from the incident. His skeleton was utterly ruined, and most of his organs has been either lost or destroyed. He was surrounded by doctors and scientists, of all nationalities and backgrounds, and kept quiet as they studied him, slowly falling back out of consciousness after a few hours.

Hachi woke up the next day inside of a tube filled with liquid, where he felt incredibly different, such as not being in pain. Wires went through his fur and skin, and he looked about slowly, noticing his lower body had been regrown, and his left arm replaced with a cybernetic limb. He also noticed how his left eye had somehow returned, another cybernetic enhancement. Despite regaining his full body, he didn't feel right being in the tube. He felt as if it wasn't for his own benefit, like something was up and it wasn't just an act of kindness. Indeed he was correct, as later that day, he was removed from the tube and strapped to a machine that would electrocute him, with the scientists claiming they wish to learn the secrets of what happened at the clan base and where the Dragon Lord went.

Hachi underwent this torture for several weeks until he stumbled across a room where a tall, blue fox female was seen communicating with several scientists. Hachi knew she wasn't a natural creature, as his robotic eye had told him through an analysis. That night, he awoke the fox lady in order to find out more on what she was doing here. She claimed her name to be Sana, and that she was an advanced cyborg designed to take orders from the scientists who were undergoing research into creating bio-weapons, which was the reason they required the Dragon Lord; to further their research and progress.

The two of them escaped that night, leaving the laboratory in flames as Hachi had used the Rage Gene, a result of Araki's blood mixing with Hachi's, for the first time, boosting his will power and giving him intensely enhanced strength. With Sana's knowledge of navigating through the base, the two had made it out alive, although Hachi had taken a considerable amount of damage from using the Rage Gene for the first time, giving him a near-on heart attack, although Sana comforted him throughout, claiming he was the first person who had shown her such kindness.

The two later went to Hachi's old home, finding the charred bodies of his relatives and friends. Struck by emotional grief, Hachi swore to avenge his clan, despite his hatred for his father and brother, who were amongst the charred corpses. Finding an old, red-tinted katana amongst the ruins of an old temple, Hachi claimed this was the true Sword of Hachiman, supposedly used to have slain the demonic hordes many centuries back.

The two would continue to travel together for about three years, as a couple, before the two went seperate ways due to reasons neither would discuss, mainly because Hachi refuses to talk about it and Sana erased her memory of Hachi some time ago. During this time, Hachi would fight huge hordes of demonic creatures and other scum.


Hachi vs Soren

Hachi against his son Soren.

Although Hachi and Sana went their seperate ways, Hachi would continue to fight off the demon threat, and would also find a new love interest, with whom he had two children with; Soren and Hincho, who would both grow distant from their father due to his absence in their developement, as Hachi went off to fight more demonic threats that would plague the world for many years. And because of his absence, the two of his sons would grow to become enemies, hating each other for a variety of reasons, which Hachi would never forgive himself for as Soren now wishes him dead.


Hachi is a rather optimistic character, although he can become quite upset if a female insults him or upsets him somehow. He likes the company of girls, but not because he wishes for relations, but because he gets on better with them than he does with men, who he will often try to joke with unsuccessfully. He can be seen as rather blunt or even dumb at times, but he is actually a strategical and tactical genius when it comes to fighting and the field of battle, in which he can be a cold and ignorant individual, stubborn and hating to lose in a serious fight.

Around females, he is rather shy and submissive, not wanting to bother them although his curiosity gets the better of him in a variety of ways, either good or bad. Around men he is rather confident, though can be seen as a nuisance at times due to his nearly-always positive personality and his tendency to brag about how he lost his family when he is met with a bad situation.

Powers and Abilities

Enhanced Strength

Despite looking relatively thin, Hachi actually possesses enhanced strength due to his regrown muscle tissues being fused with his cybernetics, and as such he can lift and throw cars with ease if he wanted to, which makes the force behind his sword a lot more devastating, especially considering the sword is demonic in nature thanks to being stained in centuries-old demon blood, which has the sword produce an almost endless amount of energy that helps Hachi when he needs it. However, Hachi prefers to use his natural strength rather than the strength granted by his cybernetics, which he would mainly use in a serious fight. He is also in possession of a metal skeleton, which further boosts his strength.

Rage Gene

Hachi is the carrier of the Rage Gene, an effect of Hachi's blood being infused with that of the Dragon Lord's own blood. The Rage Gene acts like a much more dangerous of an adrenaline rush, granting Hachi an enhanced amount of strength and reflexes, as well as speed. The gene is demonic in nature, though Hachi has no control of the gene, which tends to activate only in cases of intense amount of stress, and is seen as a curse by Hachi himself as, with every generation down the line, the Rage Gene's influence becomes stronger and stronger. Hachi has only managed to access 15% of the Rage Gene at most, although if he was to access 100% he would be the centre of a black hole capable of destroying a majority of the known Universe, which he doesn't know. but is a reason to further dread this demonic ability.

Swordsmanship & Martial Arts

Hachi is skilled in the art of swordsmanship, and was taught from an early age how to handle a sharp blade. Thanks to his cybernetic implants, he can analyze a weapon and know almost instantly how to adapt to its usage, and store the information for later uses just in case. This applies to a majority of weapons, such as swords, axes, daggers, etc.

Hachi is also a skilled martial artist, also having been taught this from a young age. His main style of martial arts, when he applies it, is Karate and other such forms, like Daito-ryu Aiki-jujutsu, Aikido, and Judo. He can analyze different fight styles, whether organized or improvised, and save such techniques for later.


  • Hachi was inspired by Miyamoto Usagi from the Usagi Yojimbo comic series.
  • Although not actually styled upon, Hachi shares some similarities with Dante from the Devil May Cry series, due to the fact of possessing a demonic sword and also having a demonic brother.
