Tatsumi

Tatsumi is a hulking man and the leader of the ninja clan that Kenshin battles while searching for Tomoe. In the OVA, he appears as a physically fit elderly man dressed in ninja attire, who delivers a severe beating to Kenshin before Kenshin kills him. His character places great importance on Tokugawa values. It is also worth noting that in the OVA, he speaks frequently, whereas no other members of his gang are ever shown speaking.
In the manga, he is depicted (much like many of Kenshin's other foes) as being literally twice Kenshin's size. His attire resembles a judo uniform more than a ninja outfit (similar to Inui Banjin), and he lacks pupils. He was Inui Banjin's master, and his death at Kenshin's hands serves as the pretext for his student to join Enishi's Jinchu campaign. His portrayal in the manga is more brutal (he states they will kill Tomoe after Kenshin's defeat).
