No. Character from a series I could probably bet money on you hating and not lose. I don't think you need to know much more than this: the character named is basically a Faustian bargainer taking advantage of naive young girls and it's entirely possible that Akio as he now stands might find him to be sufficiently loathsome as to not want him around.
