Renji Sakara is an ordinary high school student with a simple dream—confess his feelings to the girl he likes, Aika, the quiet and mysterious beauty of his class. So when she unexpectedly invites him over to her house, he feels like the luckiest guy in the world.
But his dream quickly turns into a nightmare. Aika drugs his drink, and when Renji wakes up, he finds himself strapped to a ritual circle in a dark basement, surrounded by eerie symbols and blood-stained relics. Aika, once kind and gentle, now stands before him with a wicked grin.
"Finally… after so many sacrifices, it worked!"
Before he can react, his body twists and contorts—his flesh reshaping, his bones cracking, his mind drowning in a storm of unfamiliar instincts. Renji is no longer human. He is something else.
