Nice old-fashioned school/mystery story for teens and "teen adults". The idea of a 15 year old graduating from MIT and going back to school in Japan is of course crazy i.e. pure manga~~~but I like Nakamura Aoi, though he really needed a hair styling makeover when he did this (or perhaps that was part of the old-fashioned setting). If I was him I might feel the urge to kick her ankle now and then, but it was an endearing show, it really felt like a school story, though a really old-fashioned school, the clothes were pretty awful. I loved the end music. I especially liked the episode with time travel. I may well watch again in future.
