Takafumi Maeuchi

Shinpei Ajiro travels home to attend the funeral of a childhood friend, and finds the remote island plagued by a sinister, supernatural force.

The story is set in a prison in the near future. It revolves around Hina Saotome, imprisoned despite her innocence, and the elegant yet sadistic guard Aki Myoujin. Hina's heart and body are at the mercy of Myoujin's "heartless yet sweet domination" from physical examinations to lovers' prison visits.
