Enjutsu declines to return the sword to Ryuubi. Ryuubi begs that she will do anything just to get it back, and Choukun suggests Enjutsu to exterminate the monster in her territory. Ryuubi's party go to the shrine that there is a rumor about the monster to exterminate it, but Kan-u and Chouhi faint for the first time. Koumei describes the monster to Enjutsu, which freaks her out, and she suggests Enjutsu to give Ryuubi's sword back, beside they will give her "the mystery mug" (just an ordinary mug Koumei buys from the gift shop) in exchange for the sword. Koumei tells the party about the plan, and they come to defeat "the monster", again. That time, they caught the children who make the monster, and find out they are orphans gathered there for many reasons. Koumei tells them she has a plan to protect the shrine. She tells Enjutsu about the sword turning to dust while fighting the monster, and suggests her to build an orphanage or else the monster will come back. Ryuubi's party pretend to be ghosts to scare the wits out of Enjutsu but somehow she is freaked out by some "true" ghost (she seems to be the boy's deceased mother Ryuubi gives flowers to). So, Enjutsu does what Koumei says.

Ryuubi is really happy about giving her sword back. In the way to return Touka, the party stops to rest in a village. They're mistaken to bandits, then their leaders Riten and Ukin attack them. Shortly after that, the mistake is clear and their other leader, Gakushin, brings a formal excusement to them. They find out Gakushin's group plans to join Sousou's army due to her good impression, but the bandits around there attack them many times and they don't have plans to defeat all the bandits, though. Ryuubi's party decide to help them. Koumei plans to use the Ryuujin-ko (the near lake) to help defeat the bandits (a flood attack using the rain, the bridge, the lake and the riverbed). They build a floodgate due to Riten's construction talent. Following the tactic, a small group attacks the bandits' camp to lure out them. When they arrive the riverbed, Riten will follow Koumei and Ryuubi's signal to open the floodgate to use the water attack. But the large rock falls and halts the water. Ryuubi uses her sword to a lightning rod and the lightning breaks the large rock. Finally, the flood attack is successful. Ryuubi asks Kan-u to be her younger sister, but Chouhi says she only accepts Ryuubi as her older sister, and the bond is built.

The Chou sisters continue to use Taihei Youjutsu to gain what goods they want with Ukitsu secretly watches over them. Ryuubi breeds Kan-u food, that makes her embarressing, and Chouhi gets jealous because Kan-u doesn't do that to her. Seeing that makes Koumei remembers about the past, about her elder and younger sisters. The party pasts by Koumei's home city and Chouun gets lost again. Arriving Suikyou's house, a girl with witch outfit opens the gate and runs to the home because they wield weapons. Suikyou introduces the timid girl, Houtou, to the party. Ryuubi says Koumei and Suikyou make a good family that makes Houtou a bit jealous. Suikyou arranges the bedrooms for the party, but Houtou doesn't want to take the same room with Koumei. The day after, Houtou wants Suikyou to go picking up herbs as she has promised but she can't go, and Koumei suggests she will go in Suikyou's place. Houtou silently goes with her, but she doesn't seem a bit interest. She gets angry at Koumei and runs away, telling her she doesn't want them to be friends. Houtou falls into a hole in the old bridge, merely catches the bridge's rope. Koumei, despite her scare, manages to go to Houtou's place and helps her up. Their relationship gets better and Houtou says goodbye to Koumei with promise she will visit her someday. The Chou sisters' performance is thwarted by government's soldiers. Chouhou gets angry and commands her audience to get the soldiers.

The Chou sisters' inn gets destroyed due to the attack of Chouhou's audience. The audience does too much and that makes the Chou sisters fugitives. They decide to get more and more supporters so the army can't touch them anymore. Bachou's cousin, Batai arrives to Touka village and plays a trick on Bachou. Bachou gets angry and wants her to go back to Sairyou, but Kouchuu calms her down and she forgives Batai. They have strict exercises in the morning. Batai gets exhausted many times but Bachou doesn't have her stop. Batai makes a bet with Bachou that she can't help wetting herself and makes her drink a lot of water and hold it until the dinner. Bachou uses many methods to hold it in, and she ends up with releasing "it" in the river. Ryuubi's party comes back, and the fishes Kouchuu uses for dinner is from "that" river. After the dinner, Koumei holds a meeting about Sousou inviting them to join her army to wipe out the Yellow Turbans led by the Chou sisters. Later, Kan-u, Ryuubi, Chouhi and Koumei depart for battles, leaving Touka village to Kouchuu, Bachou and Batai. In the main camp, Sousou and Kan-u talk about the flag of Ryuubi's army. They meet Enjutsu and Choukun again. Sousou gets troubled because the number of Yellow Turban's army gets bigger and bigger, and Ten-i reports to her that Kada wants to meet her again.

Kada guests the Yellow Turban Rebellion is caused by the Taihei Youjutsu. Juniku suggests an all-out battle against them but Ryuubi doesn't agree with that. Kada tells his ideas. They agree with him to use another songs of another singers to affect the Yellow Turbans' hearts, make them leave the rebels. And they use Enjutsu and Choukun's talent in music, and Teiiku suggests adding Kakuka. When Kada returns, he gets three magic crystals from Gotobedou's head with limited magic. They execute the plan. Ryuubi, Kan-u and Chouhi, Gakushin, Riten and Ukin, with Kada and the three singers Enjutsu, Choukun and Kakuka drive a big car to the rebels' tents. The song contest goes on. The magic of Kada runs out and the rebels follow Chouhou's order to get them. Ryuubi and Kan-u, Chouhi start singing with the help of three singers Enjutsu, Choukun and Kakuka, and the rest. Then, sings from the hearts win sings from the magic. The Chou sisters realize that their dreams from childhood weren't like that, and they disband the Yellow Turbans. Even before the present Kada seals Taihei Youjutsu, Ukitsu appears, takes it and disappears. In the meeting to decide the Chou sisters' and Yellow Turbans' punishment, Ryuubi supports to get their punishment as light as possible, so as Riten. Kakuka suggests for all them join Sousou's army. Koumei, Teiiku, Gakushin's group support her and Sousou decides to do as Kakuka suggests.

Ryuubi and her party come Kousonsan's city. Kousonsan welcomes them and is surprised that Ryuubi comes with them. She tells them that the sword isn't here now. Because Enshou's lending food for her city, Kousonsan must give it to her as a proof that she will repay Enshou. The party goes to Enshou's place. They're involved to Enshou's stupid games as usual. Koumei loses 0-100 to Ganryou in Question Game (about Enshou's secrets). Ganryou loses Ryuubi 11-13 to Eel Catching (by breasts) Game. And the games later with Bunshuu and Chouhi in Arm Wrestling, Ganryou in Tongue Twister, Bunshuu and Kan-u in Imitations, Ryuubi in "What's in the box?", Bunshuu and Chouun in Staring Contest, Ganryou and Chouhi in Bean Carrying, Clam-matching, Cosplaying and the games come to a tie 150-150. The last match, Kousonsan and Enshou in Sumo Wrestling of Ladies wearing a swan loincloth (though Kousonsan wears her white-horse loincloth), ends with Kousonsan's win (her power goes up while she remembers how unnoticeable she was). Though, Ryuubi can't get her sword back because Enshou just lended it to her cousin Enjutsu before (through Choukun's saying that is a pun of The Emperor's New Clothes). Kousonsan doesn't have to pay for the food Enshou lended her city and Ryuubi's party leaves for Enjutsu's city.

The Chou sisters try to get their money by performing magic and music, though it's hard to deal. A man claiming himself Ukitsu gets them a little dream and gives them the Taihei Youjutsu (Crucial Keys to the Way of Peace) book full with magic references. Chouhou uses the magic to create three magic crystals (somehow it resembles a microphone) and the three sisters plan to put their first magnificent performance using this, and they get successfully. Their successes come one by one, and they have been famous more and more ever. In the way to Enjutsu's city, Ryuubi is caught off by a poster of the Chou sisters, she suggests the party to take a look at them. The party goes to see a performance of the sisters, and stops a small fight in the performance. The sisters start to think about the way to get rid of the annoying matters that may cause problems to them someday. Ryuubi's party leaves to continue the journey.
