Inuyashiki is a strange, violent, and often funny anime about a middle-aged man whose body is replaced by a combat robot. The premise is simple: aliens strike down Inuyashiki Ichiro, a lonely, friendless businessman, and swap out his flesh for a mechanical frame. He could have crushed buildings and ended wars. Instead, he uses his powers to heal sick children and chase petty criminals. Across eleven episodes, the show tracks two men who share the same origin but move in opposite directions, one devoted to saving lives and the other to taking them.

Two Men, One Origin
Ichiro Inuyashiki is the heart of the series. He is 58 years old, divorced, ignored by his family, and utterly alone except for his dog, Hanako. After the transformation, he dedicates himself to doing good. He saves a homeless man being beaten by teenagers, heals children with incurable diseases, and patrols the streets for wrongdoers. His actions are small and humane. He does not seek fame or power. He simply wants to help.
Hiro Shishigami is the opposite. He was a teenager standing beside Inuyashiki when the aliens struck. Like Inuyashiki, he gains incredible strength and speed. Unlike Inuyashiki, he finds his purpose in killing. He murders classmates who annoy him, families, and children, purely for enjoyment. He calls it his way of staying human. The police cannot stop him, and he becomes the most wanted criminal in the country.
The contrast between the two men is the engine of the story. Both were altered in the same way. One chose kindness. One chose cruelty. The show spends its runtime exploring why that difference exists, and the answer is never simple.
How the Show Works
The series is built around a simple but effective power system. When Inuyashiki or Shishigami fires a finger gun, anyone who sees it dies instantly, as though shot by a real bullet. Shishigami can also shout “da-da-da” while pretending to hold a machine gun, with the same result. These mechanics allow for fast, brutal action scenes that play out with a kind of grim comedy. A finger gun fired at a television screen kills everyone watching. A shout in a classroom kills every student. The rules are consistent, and the show respects them.
The animation comes from MAPPA, and the visual style is clean and efficient. The robot bodies are sleek and metallic, and the action sequences are choreographed with care. The show is not flashy, but it does not need to be. The focus is on the people inside the suits, not the suits themselves.
The Voices Behind the Suits
The voice acting carries a lot of weight in a show this talky. Fumiyo Kohinata plays Inuyashiki, giving him a soft, worn voice that contrasts sharply with his immense power. Nijirō Murakami voices Shishigami, and he sells the character’s cold, amused cruelty without ever tipping into cartoonish villainy. Kanata Hongo voices Naoyuki Andō, Hiro’s childhood friend, who tries to pull Hiro back from his path of murder. Sumire Uesaka voices Mari Inuyashiki, Ichiro’s teenage daughter, who serves as a bridge between the two worlds. Each performance is distinct, and the show’s emotional weight rests on these voices carrying the dialogue.
Comedy and Horror
The show is not a tragedy. It is a dark comedy, and it knows it. Shishigami’s methods are horrific, but the show frequently cuts to his face splitting into a grin as he kills. The finger gun and the machine gun shout are presented as absurd, almost cartoonish, despite their deadly results. This tonal instability is a deliberate choice. The show wants you to laugh and recoil at the same time.
The humor comes from the gap between the enormity of the stakes and the mundane nature of the characters. Inuyashiki saves a child from leukemia. Shishigami kills a classmate over a minor insult. The scale of the action is cosmic, but the motivations are petty. That tension is what makes the show memorable.
What Works and What Doesn’t
The show’s strengths are easy to identify:
- The central conflict between Inuyashiki and Shishigami is sharp and compelling.
- The finger gun and machine gun shout mechanics are consistently applied.
- The voice acting is strong across the cast.
- The animation is clean and serviceable.
- The show balances horror and humor effectively.
The weaknesses are harder to overlook. Some middle episodes feel padded, and the show occasionally loses focus on its central characters. The supporting cast, particularly Naoyuki and Mari, get less development than they deserve. Their roles are essential to the story, but their arcs are thinner than Inuyashiki’s and Shishigami’s.
Final Word
“Inuyashiki” is a flawed but potent piece of work. It takes a simple premise and stretches it thin, then tightens it again. The show’s best moments are its most committed ones, when it leans fully into its dark comedy or its pure horror. The worst moments are the ones where it drifts, losing focus on the two men whose story it is supposed to tell.
The anime runs 11 episodes on Fuji TV’s Noitamina block. It premiered on October 12, 2017, and concluded on December 21, 2017. The series was adapted from Hiroya Oku’s manga, which ran in Kodansha’s Evening magazine from 2014 to 2017. A live-action film followed in April 2018.
This reviewer rates the anime at 8 of 10. The show is not perfect, but it is ambitious and mostly successful. It asks difficult questions about power, responsibility, and the meaning of being human, and it answers them with explosions and finger guns.
