Chapter 122 of the Jigokuraku manga.
Summary[]
Shion and Nurugai fall into the ocean while carrying Gantetsusai who remains unconscious. Jikka then tries to bring them onboard the ship as requested by Shion but falls into the ocean as well due to being intoxicated, much to Shion's annoyance. After everyone (including Yuzuriha) is brought back on the ship, Jikka lets them know that it would not matter if they had saved him since he believes that Rien is unstoppable. While on the other ship, Rien senses Tao growing from where Gabimaru and Sagiri's are at, to which she found irritating, and is confronted by the two in battle. Rien fends them off and uses a bolt of Tao lightning but misses Sagiri after Gabimaru grabs her out of the way of her attack. Nurugai and Shion watch as Gabimaru and Sagiri are fighting in perfect synchronization but know that a clear strategy is needed. Gabimaru is handed Sagiri's sword and comes in to strike Rien's tanden. However, Jikka notes that that strategy will not work since the hindering attribute will lose the necessary power. Using another strategy, Gabimaru attempts to use Sagiri as a human sword by holding her by her legs while she holds onto her sword but quickly dismisses the idea. In light of their ridiculous tactics, Rien sees that she cannot afford to waste any more time fighting them and must take down Sagiri using her strengthened arms. Shugen looks at Sagiri and remembers how he felt worried at the time she was selected for the shogun's mission due to her kindness being a hinderance but starts to see her in a new light. Sagiri remembers how Gabimaru pointed out to her how she lost to Shija due to giving in to her anger instead of focusing on the middle path that gives Tao its power and accepts that both strength, weakness, and doubt make her who she is. After her Tao is strengthen, Sagiri attacks Rien with a clear mindset of knowing that she is the "spear" that will take her down while Gabimaru is the spy from within the shadows. Knowing that Rien's goal is to revive Jofuku, Sagiri focuses on attacking her while Gabimaru directs his attention towards the Hōshi's gilded corpse, as well as the Paradise Butterflies, and plans to destroy both as a way to have Rien's Tao weakened from rage that will give Sagiri an opportunity to cut her tanden.
