Kodomo no jikan: Kuro-chan to Shiro-chan

Dragon Half

Mink - the daughter of a dragon and a retired dragonslaying knight - sets out on a journey to get tickets for a concert held by Dick Saucer, world-famous teen idol and dragon hunter. Meanwhile, the corrupt king of the land is trying to take her hostage to get at her mother, and his magic-using daughter seeks to foil Mink's quest out of sheer spite.

A parasitic alien soul is injected into the body of Melanie Stryder. Instead of carrying out her race's mission of taking over the Earth, "Wanda" (as she comes to be called) forms a bond with her host and sets out to aid other free humans.

Star Trek IV: The Voyage Home
