Yoshikage Kira

"I simply want a peaceful life. It's just that it's in my nature to kill..."

- Yoshikage Kira

Yoshikage Kira (吉良 吉影) is the main antagonist of Diamond Is Unbreakable.

Kira is a paraphilic serial killer committed to defending his uninterrupted lifestyle.

Kira is also featured centrally in the short story Dead Man's Questions.

Appearance
Yoshikage Kira adopts one face other than his original one in Part 4, and a ghostly body resembling his original, with a unique outfit, after this. He remains a man of average height and slim to athletic build.

Original
Kira has light, loosely combed back hair with a few strands out of place. He wears a light suit and a dark tie patterned by a column of skull emblems with upright, cat-like ears, similar to those on his Stand, Killer Queen. As a salesman by profession, he wears a similar suit throughout the series, though he usually takes off his jacket at home.

Kosaku-Kira
When Kosaku Kawajiri is killed, Kira assumes his facial features, including his spiky black hair, thin, dark eyes, and higher cheekbones. He retains his suit, changing only his tie.

After being hit by the Arrow and receiving Killer Queen's third bomb, Kira's hairstyle spontaneously changes, becoming perfectly combed back, light, and striped by black strands.

Ghost
Immediately after his death, as a ghost, he retains Kosaku's features for a few moments before reverting to his original appearance, which he retains in Under Execution Under Jailbreak.

Henceforth, he adopts an elaborate outfit consisting of a dark bowler hat with an upturned rim and a tie, both patterned by concentric squares, and, shirtless, a dark, lapelless suit.
