Banjin Inui

Inui is a camaflouge-wearing, hand-to-hand fighter who mirrors Sanosuke in intelligence. He is the student of Tatsumi, the leader of the ninja group that tried to kill Hitokiri Battōsai. Inui claims to join Enishi's Jinchū campaign for that reason, but he's just using his master's death as an excuse to fight and prove how powerful he is. Inui wears gauntlets on his wrists called tekkō that according to him can deflect any attack, even bullets. He wears them to compensate for the fact that he can't take damage well. Inui is skilled in Jutsushiki Muteki-Ryu, which is an amalgamation of various styles of martial arts. He likes to boast about being invincible and undefeated, but Sano figures out that he's just full of himself from wearing the tekkō and that he only fights people weaker than him. (Source: Wikipedia)
