Benjamin Herrmann is a cynical loner, cold and close-minded. However, that won't help him as his mother secretly signs him up for a student exchange program. Now he must spend a year in Japan, at the Tatsuya High School finishing a checklist that needs him to be the exact opposite of himself.
On arrival he meets his assisting student: Mizuho Sakiyurai. She makes it their mission to finish the list by the end of the year and tries to break down the walls around her new friend from the west.
Benjamin starts his first day at Tatsuya High. The only foreign student makes him stand out nearly wherever he goes, which is why he decides to do everything in his power to remain a nobody while in Japan.
But it seems as if a girl wearing a blue ribbon has something to say about that...
