Hizuki Reiji is a high school Japanese teacher, who just got entangled into a mystery when he moves out of his town to go and take a substitute teaching position. The woman he's replacing (Sakuraba) disappeared two weeks ago and rumor has it that the problematic student, Magaki Kyoichi, was seen the night before with a blood-stained knife. Cops are investigating the issue but what really happened to Sakuraba-sensei? And how are Hizuki and Magaki involved?
