ソードガイ ヱヴォルヴ

Gai Ogata lost his right arm as a boy and got it back as a blade: his adoptive father Amon, a swordsmith, rebuilt the limb from shards of the cursed sword Shiryu. That makes Gai a Chrysalis, a person who has taken a demon weapon's power into their body and risks hardening into a Busoma, an armored monster that only wants to kill. This sequel manga keeps Gai between the Shoshidai, the body that hunts those weapons down, and the factions that would rather see what he becomes.
