Shiinamachi-senpai no Anzenbi

A message from a senior library monitor, Shiinamachi Kaguya-senpai, invites Sakuradamon Jirou to visit her room on what she calls her "safe day." Excited, Jirou goes to the Clock Tower Caretaker's Room, only to find Senpai unconscious and covered in blood. The situation quickly takes a surprising turn. A suspect may be among those close by. Unraveling Senpai's hidden secrets becomes urgent, as does uncovering long-buried truths about Jirou's own past and concealed family connections.
