Please Teacher - Hot for Teacher (Vol. 1) - With Series Box
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, and predictable complications ensue. The idea of a  teacher-student romance apparently plays better in Japan than does in the U.S.,  where images of a boy who looks barely pubescent and a voluptuous older woman  smack of child molestation.
