Hyper Speed GranDoll (超光速グランドール, Chō Kōsoku Gurandōru) is an anime OVA about a high school girl who discovers that she is really part of a royal lineage of aliens from a distant planet.
While Koichi Amagi is making a marriage proposal to his beloved Miki, a space ship fell right in front of them.
A game based on this OVA was released for the PlayStation in Japan which is an action sidescrolling platformer similar to Metroid and Megaman.
There are 3 episodes: Bamboo Dong of Anime News Network described Hyper Speed GranDoll as being very predictable, comparing it to a "color by numbers" book.
[1] Chris Beveridge of Mania.com expressed similar sentiments, calling the anime "fun" but also "by the numbers".
