Ren

煉

Ren is one of the three Sanada demons, extremely powerful ninjas, who operates under the guidance of Misanagi, the leader of the Sanada. He fights alongside his comrades when Himura Kenshin and his friends, assisted by a former Sanada member, attempt to thwart Misanagi's plans.
During his encounter with Himura Kenshin, he manages to neutralize one of Hiten Mitsurugi-ryuu's moves by using a technique of his own called "Death Run." This appears to be the only move Kenshin can perform, since he is unable to close the distance to Ren's range due to a spell cast by Baku's bats.
