If you read the comment below then you be like WTF, and then question how does the DxD world function. And yeah Issei body comes from Great Red's flesh and is formed using Ophis' powers so he can be consider to be in those two categories and if you add the Boosted Gear that would make three but like Cao Cao said he does not fit in those categories as well. Maybe we should come out with a new nickname for Issei.
