Chapter 118 of the Jigokuraku manga.
Summary[]
Knowing that Rien's Tao is too powerful, Yuzuriha and Gabimaru decide that the best course of action is to try to have her deplete her Tao, similar to how they went about during their battle with Ran, with the two of them along with Gantetsusai and Nurugai as distractions. Yuzuriha makes the first attack by using her ninjutsu to create armored soldiers. She then remembers the warning about the I Ching but puts her faith that Sagiri and Shion will make the finishing blow. Rien destroys Yuzuriha's armored soldiers but is struck in the head after failing to notice Yuzuriha charging towards her. She then sends her back with a Tao attack but is attacked by Nurugai next, who remembers Shion's teachings and cuts Rien's left arm using Tenza's technique. Rien uses her severed arm to grab ahold of Nurugai but has her limb cut off by Gantetsusai. Gabimaru and Gantetsusai then use a coordinated attack to cut Rien in half and set her on fire. With Rien left wide open, Gabimaru calls out to Sagiri and Shion to perform their combined attack to destroy Rien's tanden. Rien is then bisected by the Asaemons and has her upper body sent flying in the air, bringing an end to the battle. However, the Tensen reveals that the events that had transpired was a Tao illusion created by her, which reveals to Sagiri, who is left unscathed, that everyone (except for Shugen, Isuzu, Kiyomaru, and Gabimaru) has fallen. Having been put up with enough of their foolish resistance, Rien enters into her Kishikai and tells the humans who are still conscious that she will soon transcend into the world beyond this after she sacrifices the people of Japan.
