Kei Kusanagi has a mysterious illness that causes him to enter a comatose state whenever he gets upset. One "standstill" lasted three years, so Kei looks like he's only 15, although he's actually 18. One night, he sees a UFO land and encounters a beautiful alien; the next day he discovers she's Mizuho Kazami, his new Japanese teacher. (She's really a half-alien/half-human agent sent to observe Earth by the Galaxy Federation while posing as a teacher.) When the principal finds Kei and Mizuho locked in an equipment room, they claim they're secretly married to avoid a scandal. Kei's lecherous uncle insists they get married. Homework, dating and a gorgeous wife - going to school has never been quite this fun.Contains the entire 13 episode series across 4 volumes in a Deluxe Collector's Art Box.
