Junpei is a skilled ninja who talks in the third person. He is fluent in Japanese (his native tongue), Latin, and French, and speaks passable English. He is also quite skilled in the ways of L33T.
He is quite friendly and out-going, if a bit heavy handed in his behavior. Junpei is often quite confused by Americans and their doings.
When he knows that a battle is to unfold, or he is looking for trouble, Junpei discards his sweatshirt in favor of a black leather trench coat. He will also arm himself with his heavy iron quarterstaff, which he wields quite easily.
Junpei is a member of the Hidden Serpent Ninja Clan, which operates under contract over in Japan. Junpei became interested in L33T when he was defeated in 'Mortal Kombat' by an American.
