Tenshi no Tattoo

Misaki is a regular girl except for the odd birthmarks on her back, like angel wings. One day, a mysterious young man appears in Misaki's life, changing it forever. He saves her life, then passes out from hunger. This mystery guy is actually a soldier from the future who has been sent back through time to kill Misaki, for in the future she is the mother of an evil ruler. The trip through time has caused him to forget his mission until after he falls in love with Misaki. An evil, satanic wizard named Kira is also after Misaki, and he will do anything to father his child with her.
