Kyōma Mabuchi (マブチ・キョーマ Mabuchi Kyōma?) is a Recovery man from Mary's Recovery House and partner of Mira Yurizaki who is later revealed to be one of the few survivors of the now defunct anti-coil unit Grendel.


Young Mabuchi

Young Kyōma

Kyōma has short spiky black hair, a short ponytail tied in the back with what appears to be two white cloths, sideburns that go down to his chin, and a small beard with a goatee and deep black eyes. He also has what appears to be a short vertical scar in the middle of his lower lip. He also has slightly tanned skin, and is mostly seen frowning most of the time.

Kyōma is distinct in his style of dress, a combination of both modern and traditional Japanese attire. He wears a red happi festival coat with a light-colored power symbol on the back, a blue gi with a black and gray-striped obi sash, black undershirt, black pants with three white horizontal stripes on the upper left leg, large blue straps on the lower legs, and sandals with black socks and blue straps, which are traditionally worn by ninja. The interior of his happi is lined with pockets that hold his signature Skewers. In the past when he was still in high school, he wore a black Gakuran school uniform typical of male high schoolers and notably, his eyes are far less fierce and more softened in expression, his hair was also shorter, but still spiked and his bangs fell into his face, which were also spiked. During his time with Grendel, he wore the standard armor typical of soldiers in his unit, a black bodysuit over which he wore tan-colored armor and had light gray war paint on his cheekbones.


Kyōma is rough-mannered, sardonic and somewhat anti-social. Kyōma likes to live in the past, with a love for vintage cars, simplistic and old-fashioned clothing, and hatred of coils. He is a strong fighter and a strategist, and often uses his surroundings to his advantage. He is prone to use violence as a response to many scenarios, and likes to slap, or kick Mira Yurizaki when she does something he doesn't approve of. Kyōma rarely has an expression on his face other than a frown, but there are some things that can trigger other emotions from him. Notably, he can't bear to see the sight of children getting hurt, and he sometimes can be rather impulsive, especially when it comes to things like his comrades in Grendel. Despite being someone who lives in the past, he tries his hardest to run away from it. And despite being quite rude at times, he can also be quite nice at others, such as acting very kindly towards his older sister Tsubaki Azumaya, and refusing to use violence towards children, and even complimenting Mira when she saves his life. He can also be quite sympathetic to others, such as with Salba Ene Tibesti and even Haruka Seameyer. He's also willing to work with people he otherwise doesn't like or care for such as with Albert Schumann or Koorogi. Most of the time he's a realist in his views, but is often surprised by certain aspects of coils, such as the ghosts of Lake Yasogami or the zombies in Easter Island. Kyōma is very focused and determined to do his missions well, such to the degree that he refuses to save a girl (who turns out to be Mira) when he sees her in the hideout of the Won brothers, and in Easter Island tells Mira to throw away a coil he finds unimportant to his mission at hand.

After the events of Easter Island, his behavior towards Mira becomes much more hospitable, and later on somewhat affectionate in a rough sort of way. Mentioning she seems less like a robot every day, he begins to show a more respectful attitude to her; though he still prefers to call her a Bucket of Bolts, or Bolts in the manga; or Piece of Junk in the anime.


Kyōma was born in 2039 in Tokyo, Japan. As a child, he only had his father since his mother passed away while giving birth to him. His father was a car mechanic, but with the discovery of the Dimension W and its unlimited energy, fossil fuels soon became a thing of the past.


As a veteran of Grendel, Kyōma is an expert fighter and hand-to-hand combatant. He can hold his own against multiple stronger opponents and is fast enough to dodge gunfire from a hovercraft. His weapon of choice are several needle-like throwing knives called Skewers, sharp enough to destroy illegal coils and blow out a car tire. His accuracy when throwing his skewers in nearly impeccable. He will also wield them as claws for close-range combat. Some of the knives are attached to indestructible wires and are used for restraining opponents and reaching higher areas. He will even use specialized knives that contain powerful explosive charges, tasers, and flash bangs. As a member of Grendel, he also used Coil-powered needles called Spin-darts that could penetrate energy barriers and explode when thrown. His happi coat is also composed of steel-woven fiber, making it similar to chain mail and almost impossible to burn or cut through. His Gift allows him to calculate and even alternate the trajectory and force of a moving object, even in distorted space.

Kyōma is an equally skilled mechanic, a talent likely picked up from his father. He is sometimes shown successfully repairing his ride, a requirement in an era where gas-powered cars have become obsolete.



Kyōma's boss at the Recovery House, who assigns most of his coil-hunting missions and rewards him with hefty amounts of money, although he takes half his pay in gasoline.

Mira Yurizaki[]


Kyōma and Mira reunited in Volume 16.

Mira is a mysterious android girl whom Kyōma encountered on one of his missions, eventually becoming his partner. Due to his dislike of coil-driven tech, he always calls her "Robot" or "Piece of Junk" In the anime, or "Bucket of Bolts" and "Bolts" in the manga, and thinks very little of her. Despite this, he allowed her to live in a trailer outside his gas station. He slowly comes to accept her as a person as the series progresses. After the Easter Island incident, their relationship improves drastically and he treats her with much more respect and even affection. After later joining up with Mira and Kyōma and witnessing Kyōma's rough but caring attitude towards Mira, Ellie has slyly insinuated that Kyōma may be falling for Mira, much to his annoyance and slight embarrassment. During the final arc of the manga, he openly admits in his battle against Drake Horton that she has become as important to him as Miyabi Azumaya was, revealing that he is in love with her.


Koorogi often likes to push Kyōma's buttons, and as such Kyōma doesn't like him very much. Despite this though he's willing to get help from him regarding certain matters with coils.

Miyabi Azumaya[]

Miyabi was the woman that Kyōma encountered stuck in between a bus and a wall. Eventually, they became devoted lovers. However, due to an accident with a coil, Miyabi loses her life and thus drives Kyōma's hatred towards coils.


  • In Chapter 1, it is worth noting that manga Kyōma's outfit bears a striking resemblance to Mugen from "Samurai Champloo".
  • Kyōma's car is a Toyota 2000GT while the other car used by him was a 2012 Lexus LFA.
  • Kyōma typically holds his skewers between his fingers, giving them them the appearance of Marvel's Wolverine's Adamantium Claws.
  • In Volume 9.5, it is revealed that he has living parents and an older brother. Their relationship is estranged, but they cut ties when Kyōma entered Grendel.
