Heyyyy, LR. This is Dan (LANCER) here with Souichirou Nagi from Tenjou Tenge. He's a thug high school freshman who's renowned for vandalism and generally unwholesome recreational activities. He's an obvious antihero in the sense that he isn't exactly heroic, he isn't really even the hero despite being one of the two main characters and he takes forever to actually win a fight or be important in the storyline.

Tenjou Tenge is a supernatural martial arts high school comic (hah) which starts off with two chummy thugs up get their asses handed to them by superpowered martial artists, only to then decide they want to also be superpowered martial artists. Most of the story is a flashback (seriously) before there's a little more main character action and then there's another extremely confusing flashback to fucking feudal Japan.

What I'm trying to say is that Souichirou doesn't really matter.
