Yoshikage Kira

Yoshikage Kira is the main antagonist of JoJo's Bizarre Adventure: Diamond is Unbreakable (the anime's Part 4).

He's a 33-year-old office worker (salaryman) living in the quiet town of Morioh, presenting himself as an ordinary, mild-mannered, and composed individual who deeply values a peaceful, routine-driven life without disruptions. He famously introduces himself in one iconic monologue emphasizing his normal daily habits, desire for tranquility, and aversion to anything that might disturb his carefully maintained normalcy.

Beneath this facade, Kira is a calculating, psychopathic serial killer who has operated undetected for years. His murders target women, driven by a paraphilic obsession with female hands—he severs them post-mortem, treats the detached hands as "girlfriends," and discards them only when they begin to decompose.

Kira is a Stand user, wielding Killer Queen, a powerful humanoid Stand capable of turning anything it touches into devastating bombs (with abilities evolving further as the arc progresses, including secondary and tertiary bomb techniques).

In the anime adaptation, his design features light, wavy hair loosely combed back with a few strands loose, a slim-to-medium build, and he typically wears a light-colored suit (often a luxury Valentino style) paired with a distinctive dark tie patterned with skull-like emblems that echo his Stand's motifs.

Overall, Kira stands out as a chilling, grounded villain compared to more flamboyant JoJo antagonists—his danger comes from how unnervingly ordinary and methodical he is, making his hidden monstrous nature all the more unsettling.
