Kamakiri is a tall man possibly in his thirties. He is broad in the shoulders and the chest, with long, wavy blond hair framing his thin and rather squarish face.
Kamakiri's clothing seems to pay homage to the iconic depiction of Jack the Ripper: long, dark gray coat, the same color of his top hat, with a gray belt, light gray pants and high burgundy boots. His kama are plain, with a wooden handle and a curved metal blade.
Not much is known about Kamakiri's abilities, but the fact that he was a Floor Master is proof enough of his power and proficiency in Nen. Still, he was defeated single-handedly by Jed's followers. He uses a pair of gama (kama) to fight.
