Хіміко

She has a crush on Sakamoto and cooperates with him in the Btooom! game.

Himiko always carried a stun gun where ever she goes because she is afraid of being touched by men. Yoshioka-senpai and Mitsuo Akechi have both tried to rape her, eventually resulting in her fear for men, and she said that every man on the island is her enemy. However, she slightly changed her opinion, as she realized that Sakamoto is the only one on the island whom she could trust.
