Raiden is in S4, and in all the other years, the students loved their crew leader, Hidari-san. He left a lasting impact on their hearts, earning him that nickname. Recently, Hidari-san has disappeared, and the students are worried-but during his absence, people start going missing, including Raiden's older sister, Saori. Raiden and Meika, who initially despise each other, team up to uncover the truth behind the disappearances. Their friends Yuki and Aoi force their way into the mission, determined to help, even as danger closes in. Together, they stumble upon Hidari-san's notebook-a chilling list of names, including Meika's. Can they uncover the truth before it's too late, or will Hidari-san's secrets claim them all?
