UFO Princess Valkyrie: Recap

Kazuto Tokino's struggle to keep his family bathhouse running changes completely when Princess Valkyrie crashes into it and leaves him mortally injured. To save his life, Valkyrie gives him half of her soul, a sacrifice that reduces the alien princess to the body and behavior of a small child.

Valkyrie remains on Earth with Kazuto as visitors from her homeworld and a string of chaotic incidents descend on the bathhouse. A kiss between the two can briefly restore her adult form and powers, deepening a strange bond that gradually grows into genuine affection amid all the extraterrestrial trouble.
