So yeah, Toujou is certifiably broken and starts with an unavoidable instant death ability that turns people to dust. I have no idea how he's below Johnny Test of all people.
I think he should be in the 3rd spot. Neither Yoon-Seok or the rat guy have any answers to his starting move, and
@Rikimarox2 already said he doesn't remember Yoon-Seok challenging Toujou when he was adding him, so it shouldn't really need a match.
