The Beginning of the Story, Chapter 0 ist not from him, but from Author: PsyckoSama.
Because of the nature of Anime Addventure , other Authors have written their own chapters that beginn at certain points of his work but deviate from his canon. However, nearly all Information in this wiki is only about his work (and sometimes on the works his story is based on)!
Ha has stated, that Dungeon Keeper Ami is his only story and that his main problem is time. Also: "...taking money for something that I do for fun would turn it into a chore and suck the fun from it." (comment by Pusakuronu)
