This anime series is centred on Sakuta Azusagawa, a high school student. He has a bad reputation; people believe he was responsible for hospitalising three other students. He tries to live a quiet life but everything changes when he meets Mai Sakurajima, a teenage actress, at the library. There is something very strange; she is wearing a bunny girl costume but nobody appears to notice her; in fact she is surprised that he notices her. When he asks others about her nobody seems to recognise her name despite her fame. It appears that this is a case of what is dubbed 'Adolescence Syndrome'. Sakuta determines to investigate this. Over the course of the series he resolves Mai's problem but she isn't the only person affected; he must investigate other cases, including that of his younger sister who has been suffering from amnesia.
I didn't expect too much of this anime but it turned out to be one of the best I watched this season. There is a solid sense of mystery as Sakuta tries to understand what caused each of the cases of Adolescence Syndrome and resolving it. Each case is quite different so it never feels repetitive. The characters are interesting; particularly Sakuta and Mai but the secondary characters are also fun to watch. The plot line involving his sister is particularly emotional. While to condition is obviously science fiction it gives an insight into relatively ordinary personal concerns. The animation was impressive with good character designs and backgrounds. Overall I'd definitely recommend this series.
