Denpa Teki na Kanojo

Juuzawa Juu is a delinquent high school student who prefers to keep the world at arm's length. Content with his isolation, he has no interest in forming attachments or inviting unnecessary complications into his daily routine. However, his carefully maintained solitude is disrupted when a peculiar girl named Ochibana Ame approaches him with an extraordinary claim. She insists that they were connected in a previous life and declares her unwavering intention to serve him as his personal knight. Initially, Juu dismisses Ame's bizarre assertions and wants nothing to do with her self-appointed role. He views her devotion as an unwanted burden and attempts to distance himself from her persistent presence. Yet, the fragile normalcy of his high school life shatters abruptly when one of his classmates is brutally murdered. Thrust into a chilling reality where danger lurks closer than he ever imagined, Juu realizes that he cannot navigate this crisis entirely on his own. Setting aside his reluctance, he accepts Ame's steadfast help, and together they begin a tense investigation to uncover the identity of the killer before tragedy strikes again.
