Story Overview
As children, Yuki Michio and Iwao Garai survived an incident on a small island where a chemical weapon — MW — was deployed, killing all other inhabitants. The exposure damaged Michio permanently: his conscience is gone.
As an adult, Michio is physically beautiful, professionally successful, charming, and completely without scruple. He works in finance. He manipulates everyone around him. He is also pursuing a goal that involves MW and mass casualties.
Garai became a priest. He is in love with Michio. He tries to stop him. His faith, his love, and his complicity are in constant conflict.
Characters
Yuki Michio — Tezuka depicts him as genuinely attractive in every sense — which is the point; the horror is that the conscience-removal didn't make him ugly.
Iwao Garai — His love for Michio and his recognition of what Michio is make him the story's moral center; his failure to act decisively despite knowing is the story's philosophical crux.
Art Style
Tezuka's art serves this story specifically: Michio's beauty is drawn as genuinely attractive, not monstrous. The gap between appearance and interior is entirely visual.
Cultural Context
MW was drawn 1976–1978. The chemical weapon premise engages with real history — Tezuka was aware of Unit 731 and the legacy of Japan's wartime chemical weapons programs. The work is structured as a thriller but operates as a moral inquiry.
What I Love About It
The love problem. Garai's love for Michio is not treated as pathological — it's treated as real. The question of whether love for a person without conscience can coexist with opposition to their actions is genuine philosophy drawn at length.
What English-Speaking Fans Say
Western readers describe MW as Tezuka's most disturbing work and often his most intellectually provocative — specifically noted for Michio being genuinely compelling rather than cartoonishly evil, for the ending being one of manga's most discussed conclusions, and for the work functioning as adult philosophical fiction in manga form.
Memorable Scene ⚠️ Spoiler Warning
The scene where Garai realizes the full scope of what Michio is planning — and that he has had every opportunity to stop him and hasn't — is the story's moral climax.
