* First appearance: Battle 266 * Age: Early-50s * Type: Sei * Type: Satsujin Ken * Yami Symbol: Void * Martial Arts: Kalarippayattu Sehrul Rahman is the Kalarippayattu master of Yami's One Shadow, Nine Fists and master of Ethan Stanley. He is a tall and muscular man with long hair slicked in the back and a long light beard. He wears an outfit from India and has golden arm bands around his wrists. He is at least as old as over his 50s, suggesting he's one of the senior members. Sehrul is shown to be a gentle and passive man, as seen when he stops Kushinada Chikage from pinching herself as punishment. He believes "the punishments of martial arts should be dealt by martial arts." Of the masters, he is the only one not excited about pitting his disciple against Kenichi. However, he has a lethal side to him as well, as seen when he attacks the marma points of the forces sent to detain him, with enough power to kill them had not the Ryozanpaku masters intervened and saved them. His gentleness is also mentioned by his disciple, who wanted to defeat Kenichi in order to put Rachel Stanley under his care and thus save her from the harm of Silcardo Jenazad. He also seems to have an aptitude for tolerance, as his personality rubbed off on his disciple, contrasting largely with Diego Carlo's flashy personality. Despite his overall passivity, Sehrul believes that the true form of the Satsujin Ken is emotionless. When Hongou Akira arrives at the Yami meeting after Kanou Shou's death, Sehrul comments that one must be heartless in order to effectively utilize the Satsujin Ken, disapproving of Shou inheriting his techniques. How he managed to get his disciple, a Dou fighter, to take upon or bypass this limit effectively is unknown, though it could be that he taught him to keep his emotions within himself and unleash them through his martial arts.
