Kanryū's men and is portrayed by Genki Sudo. In the fourth film, his equivalent Inui Tenmon is portrayed by Joey Iwanaga. Otowa Hyōko , the , is member number five of the Six Comrades and an effeminate-looking user of assassin's weapons or "Instruments of the Shadows". He says he has thirteen hidden weapons all over his body, but only four are shown in the series. The first is , a small six-barreled arrow-launcher worn on his left wrist. The second is the , a paralyzing mist generated by dropping two small cubes into water. The third is a jar of iron powder, , used in conjunction with his magnetic . The last is the , six long piercing tentacle-like appendages worn on his torso. His battle tactic is to outwit the opponent and catch them off guard with his hidden weapons as opposed to simply overpowering them. Otowa is a sadistic individual who enjoys killing people for fun and is not above targeting women and children. Otowa seeks Kenshin's death in revenge for the death of his friend Nakajō, whom he had competitive killing sprees with. In reality Otowa joined the fight just for pleasure. Otowa attacks Chief Uramura's house as part of the Jinchū campaign while Inui simultaneously attacks Maekawa dojo. Otowa later fights Myōjin Yahiko during the attack on Kamiya dojo. He comes close to killing Yahiko with a few of his weapons, but Yahiko eventually defeats him. As Otowa goes down he has a crazed smile on his face as he could not believe his defeat at the hands of someone not even half his age;. However, Sanosuke notes Otowa was not in peak form because he feared Kenshin's abilities and thought of fleeing after the duel with Yahiko. Otowa is arrested by the police afterwards. Watsuki had no personality model for Otowa and made him cruel because he is a shadow instrument user, which he notes resulted in him being like Kanryū. The author wanted to make him more cunning and sadistic, but said Otowa was not developed satisfactorily due to his own incompetence. Otowa's design model was a previously rejected "drag queen-ish" villain who wore a lot of lipstick. The six-pronged accessory was borrowed from Mr. Sinister in X-Men: Age of Apocalypse. Watsuki said that he feels Otowa is one of his better designed characters. Yatsume Mumyōi is a member of the Six Comrades who
