Electromagnetic Girlfriend - S01

Delinquent Juu Juuzawa is a lone wolf who doesn't see much point in making friends. So when a girl named Ame Ochibana claims they were linked in a past life, he's highly skeptical and wants nothing to do with her. What's even stranger is that her dearest wish is to be his servant. Convinced Ame must be delusional, he tries to keep his distance. But when a classmate is murdered, Juu decides to keep her close instead, believing the strange girl is the culprit. Still, her intelligence and skill start to prove invaluable as the two work together to solve the murder.
