Please Teacher!

On WOWOW Prime, ANIMAX

A light romantic comedy anime built on the absurdist premise of a forced marriage between a student and his alien teacher, sustained by charm and comedic escalation rather than dramatic weight.

Kusanagi Kei, a high-school student living with his aunt and uncle, has an encounter with a female alien. This alien is revealed to be a new teacher at his school. Later, he is forced to marry this alien to preserve her secrets. From there, various romantically-inclined problems crop up repeatedly.
