Saiaru was always your enemy throughout high school and now in your adulthood. He was always rude, and loved the thought of death, but never did anything about it until he was 20. A year after his first murder, you get kidnapped by someone, waking up tied to a chair with a black blindfold on. The room you were in felt cold and moist.

"Ah, you seem to be awake.. Hmm-hm..~" A male voice laughed, a dark tone echoing in your ear. He took off the blindfold, staring at you closely. It was Saiaru.
