At the capital Rakuyou, Ryofu Tallgeese has infiltrated the palace of Reitei Gundam, the Emperor of Mirisha. Leaving dead bodies in his wake, Ryofu proceeds to kill Reitei. Toutaku Zaku praised Ryofu for his efforts, and proceeds to take the Gyokuji, proclaiming himself the new ruler of Mirisha. Outside the palace, Ryofu encounters Chou-sen Qubeley, who calls him Housen. Chou-sen is concerned about Ryofu letting Toutaku seize the Gyokuji, but Ryofu replies his only goal in life is to seek out strong warriors to quench his battle-hungry soul. Over at Sousou's camp just outside Rakuyou, Sousou watches on as Kakouton Giros is enraged at Toutaku's plot, while Kakouen Daras feels helpless about the situation. However, they are soon greeted by a wandering strategist, Shiba-i Sazabi. He brings a treasure, the Shichiseiken, and believes that this can whet Toutaku's appetite, and be allowed an audience with him.

The Anti-Toutaku Alliance is formed, and Ryuubi, Chouhi and Kan-u make their way to the Alliance campsite. Once there, they meet up with Kousonsan, who joins his father's army in the Alliance. Ryuubi introduces Chouhi and Kan-u to Kousonsan, who makes a comment that the three combined has the strength of one hundred men. Sousou and Sonken Zephyranthes also welcomes the sworn brothers' arrival. However Enjyutsu Zssa, the second-in-command of the Alliance, is not pleased. A small squabble between Chouhi and Enjyutsu starts, until Enshou Bawoo, the commander of the Alliance steps in. Enshou comments on how the En family is privileged to lead the Alliance, and that he doesn't not need backwater peasants in his Alliance. He is soon interrupted by word that Toutaku forces has attacked the campsite.

With the defeat of Kayuu, Ryofu jumps out from the Koroukan, preventing the Son army from advancing any further. He only wants to duel Sousou, who promptly steps forward. However, Ryofu's strategist, Chinkyuu Mercurius steps in and uses his strategem of fire, a stratagem where he has doused the land with oil, to burn the advancing force. But Shiba-i has anticipated this attack, and reversed it with his own stratagem, burning Chinkyuu with his own flame. Soon, Koushun Vayeate and Chouryou Gelgoog step in to take down Sousou. However, Kakouton and Kakouen step in to protect Sousou. Ryofu grows tired, and attacks, injuring Kakouton's left eye. Sousou orders Kakouton to step down.

Back at the capital Rakuyou, Toutaku comments with Ryofu at the Koroukan, no one will pass. Riju Shokew, Toutaku's strategist comments that with the gathering of various heroes in the Alliance, Ryofu might be overpowered eventually. This leads to Toutaku commenting that it's Riju's job to make sure Ryofu doesn't fall. At the Koroukan, Ryofu stands guard as Chou-sen comments on Toutaku again. Ryofu gives the same reply, saying that all he doesn't care about Toutaku, all he cares about are battles. Over at the Alliance campsite, Kousonsen is arguing with Enshou about the next plan of action. That is until Ryuubu steps in and requests that he, Chouhi and Kan-u will take down Ryofu.

As the Son army witnesses the capital in flames, Shuuyu Hyakushiki spots Toutaku escaping in his chariot. Sonken Zephyranthes orders his army to chase after Toutaku, and to regain the Gyokuji. As the troops leave, Shuuyu requests Enjyutsu and his troops for rear support, and leaves. However, Enjyutsu grows paranoid, thinking that if Sonken Zephyranthes defeats Toutaku, the Gyokuji will be in his hands, and become ruler of Mirisha. Enjyutsu doesn't want that to happen, and orders his general, Kirei Hamma Hamma, to attack the Son army. As Sonken Zephyranthes catches up with Toutaku, he orders Ryofu to take care of the Tiger of Koutou, to redeem his honour.

Back at the Alliance campsite, Kousonsan and the sworn brothers hear the news of Sonken Zephyranthes' death, and how the Son army, now under Sonsaku, is still giving chase after Toutaku. The four decide to join up with the Son army to back them up. At the main gate to Rakuyou, the four are stopped by Chou-un Gundam, an officer under Enshou. Enshou has barred anyone from supporting the Son army's chase. Angered by this, Ryuubi draws his sword, to which Chou-un draws his spear. They both discuss how a soldier should follow a commander's orders and how one should always support their allies. Kousonsan steps in and agrees with Ryuubi's point of supporting one's allies. At this point, Chou-un succumbs, but he will personally escort them.

The Anti-Toutaku Alliance, minus Enshou and Enjyutsu, makes their way towards the Biujiyou, where Toutaku currently resides. Kousonsan decides to take a rest before crossing a river, and announces that they will begin their attack at dawn the next day, where they will rendezvous with Sousou's and Sonsaku's armies. Ryuubi decides to take this chance to fish for food. At the riverside, Ryuubi meets Koumei, and finds out that the fish are not biting. Koumei comments that perhaps a large fish has eaten the smaller fish, and Ryuubi states that if he catches that fish, the river will be at peace again. Koumei asks what if about large fish invades, and Ryuubi states he will catch that too. Koumei laughs. When Chouhi searches for Ryuubi, Koumei mysteriously disappears. Night falls, and the three factions prepare for the coming final battle, each having a common goal to defeat Toutaku, which results in the Gyokuji glowing brightly with a pure light.
