Description

A young man who threw out his name when he came to earth. He saves Ashe from some Angels that tried to kill her in the human world.
Because he doesn't have a name he lets Ashe call him Zero.

<hidden by spoiler settings>He was supposed to be Ashe's tsukaima instead of Kyle, but in the end he got rejected and thus fled to the human world.
