Overview

Ichiro Inuyashiki is 58, invisible to his own family, and has just been told by his doctor that he has only months to live. That same night, a malfunctioning alien ship crash-lands near him and a teenage stranger, Hiro Shishigami, and both are rebuilt from the wreckage into something closer to weaponized machines than human beings -- capable of flight, regeneration, and near-limitless destructive force. Ichiro uses his new body to quietly start helping people. Hiro uses his to start killing them. Written and illustrated by Hiroya Oku, Inuyashiki ran in Kodansha's seinen magazine Evening from 2014 to 2017 across 10 volumes and is licensed in English by Kodansha USA.

What it does well

The premise's real strength is its symmetry: two people, granted identical power under identical circumstances, immediately diverge into opposite uses for it, and the manga never lets you forget they're two sides of the same event. That structure gives even quiet, character-focused chapters an undercurrent of dread, since Hiro's rampage is always happening somewhere just out of frame.

Ichiro is the more interesting half of that equation specifically because of how unglamorous his heroism is at first -- he starts by helping a stray dog and an assault victim, not by fighting supervillains, and that groundedness makes his eventual larger-scale heroics feel earned rather than default. Oku's art is doing a lot of work here too, rendering both the superhuman spectacle and its human cost with the same blunt, visceral clarity that made his earlier manga notorious, which keeps the stakes feeling real even as the scale escalates.

The pacing is relentless in a good way -- each volume pushes both leads further, and the story never pumps the brakes to stall for filler.

Where it falls short

That same relentlessness is also the manga's biggest liability. The violence is frequent and graphic, including scenes of Hiro deliberately killing civilians and children, and Oku doesn't soften any of it -- readers sensitive to that kind of content should go in with clear eyes about what they're getting into. The story's interest in bleakness sometimes crowds out its more thoughtful angles, particularly its ideas about aging, invisibility, and what people actually do once consequences stop applying to them.

Ichiro's family, despite being central to his motivation, don't get much development beyond their role in his arc, which makes some of the emotional beats around them feel more functional than earned.

Verdict

This is a fast, brutal sci-fi thriller that takes a genuinely clever premise -- identical power, opposite choices -- and follows it all the way to its darkest conclusions without flinching. It's not for readers who need their violence softened, but for anyone who wants Oku's unfiltered style applied to a tighter, more focused story than his earlier work, it delivers.
