If I could be in a game series it would probably be...Persona 3. >.< I love that game and all the characters.
As for an anime...i'd like to be in...hm, that ones hard.
I would say DeathNote but theres a chance I could get killed.
Then id say Naruto, but thats so typical.
Soooo...I'd like to be in loveless since they have cat ears until there loose there virginity. XD I think that would be cool.
