Chapter 119 of the Jigokuraku manga.
Summary[]
After seeing Rien enter her Kishikai, Gabimaru prepares to use a technique against her. However, Rien instantly blasts him in the face with a Tao lightning bolt before he is given a chance to attack. Sagiri comes in to stab Rien's tanden from behind but is told by the Tensen that her Tao is too weak to harm her Kishikai body. Shugen then jumps in to save Sagiri from being crushed by Rien's Tao manipulation and orders both Isuzu and Kiyomaru to have the criminals return to the ship, explaining that they cannot allow a monster to steal the Yamada clan's duty to execute them. Before allowing them to escape, Rien dismantles the exterior of the ship while keeping the room where Jofuku is placed intact. As she holds on to Kiyomaru's hand, Sagiri becomes shocked to see that the young Asaemon has been crushed by a piece of the debris that was scattered. Isuzu becomes shocked as well and rushes towards their direction. However, Rien takes control of Isuzu's body and crushes her in front of Shugen, much to his horror. This causes Shugen to rush in and try to attack Rien in a blind fit of rage. While from behind, Gabimaru grabs onto Rien and sets her ablaze with an intense amounts of flames, which gave Shugen a chance to cut off one of Rien's arms but is also caught in the flames as well. While trying to incinerate her, Gabimaru has a sudden memory of Yui's face and ceases his attack. He then notices that his Tao is starting to resonate with Rien's and undergoes Arborification.
