Story
Diamond Is Unbreakable
Part 4 · 1962–1999Kosaku's pre-arc biography is depicted across one chapter as a Morioh-based salaryman with no Stand-user pedigree and a cold marriage to Shinobu Kawajiri. He is murdered by Yoshikage Kira at the start of the arc's identity-assumption sequence — Kira surgically alters his own face to match Kosaku's, moves into the Kawajiri household, and assumes Kosaku's identity across the rest of Diamond Is Unbreakable.
Powers & Abilities
Non-Stand-User
OtherKosaku is not a Stand User. He is structurally an institutionally-invisible salaryman whose identity Kira targets specifically because of the institutional-invisibility — Kosaku's death and identity-replacement are not noticed by the broader Morioh community.
