Jinnai Dōko

Jinnai Dōko is introduced during The Captain Amagai arc as one of Gyōkaku Kumoi's assassins. He is part of the assassination squad set to caught Rurichiyo Kasumiōji under Hanza Nukui. He faces off Rukia Kuchiki, and after she refuses to give up Rurichiyo, encases Jinnai in ice but he easily breaks free. In response, he consumes a piece of his Bakkōtō Retsurai and this gives him the ability of shoot blades from his back. Then, he throws Rukia into a building, and temporarily out her of the battle. When Enryuu and Rurichiyo attempt to escape, Rukia returns to the fight and uses a Kidō technique to protect them. Excited about the battle, Douko Jinnai eats another piece of his weapon and increase his powers once again, making it that much harder for Rukia to keep up with him. He dies in his own attempt to power up further because it causes his weapon to completely consume him. With the battle now over, Rukia approaches Jinnai's bakkōtō, however, before she can reach it, some of Nukui's men retrieve it and carry it off.
