Seems fairly odd to me since he knows who the roles are and can take out his enemies. Anyways, if it is possible for Pervy Kira to actually be Kira, my suspicions are also on him. Someone has been accusing him, and I realize that's a joke, but something Perv said stood out to me, earlier, he said "If I die, the game ends" and while I know he's the host, this could be a clever way of telling us outrightly that he's Kira while avoiding us noticing and lynching him. The fact that he hasn't done this before increases the chances of us falling for it.
