In the first season, the protagonist, Chou Soran, hiding that he is an “outsider” (someone able to use special abilities) encounters a mysterious girl named Fuu Houhou who hold the secret of eternal life. Together, they will join the Raten Tournament where they will try to solve the mysteries related to themselves. In this 2nd season that marks the beginning of this fighting tournament between Outsiders, mysteries will gradually be unveiled and new characters will appear.
The Raten Taishou is beginning soon, and the various competitors are making their way to the tournament. To sweeten the pot, Rikukin announces that he will give his Tsuutenroku technique to the winner of the Raten Taishou.
Soran and friends arrive at Ryuukozan where the Raten Taishou is being held. They make their way through the mountains and across difficult terrain to finally arrive at the tournament, where they get their first taste of the combat abilities of the other competitors.
Soran's first match of the Raten Taishou begins. As Soran is known for being heir to the great and powerful kitaigen style, his opponents decide to work together against him. Meanwhile, Shokatsu Sei, master of the ancient kimon tonkou style, breezes through his first match with overwhelming strength.
The first round of the Raten Taishou has concluded, and 32 competitors remain. That night, Soran is shocked when he learns from Chou Reigyoku's apprentices why the Tenshi's disciple respected by all seems to hate him so much. Meanwhile, Fuu Houhou's opponent Ou Niken notices something different about her...
Soran's opponent fails to turn up in time for his match, earning him a reputation as a cheater. Elder Rikukin and his group of trusted young outsiders realize Koketsu is being manipulated by the evil organization Zensei. Meanwhile, Soran receives a summons from Elders Ou Ai and Ro Ji, who demand he hand over his Kitaigen style
Fire user Kouhin is irritated that his opponent Shokatsu Sei will not fight at full strength. Shinki user Shoushou struggles against Zenshin style user Koumei. Meanwhile, Chou Soran learns from Rikukin the real reason he gathered outsiders at the Raten Taishou
When Soran is shocked to learn from Elder Shinchuu that his grandfather Chou Kaigi was a member of Zensei, the Tenshi and Rikukin explain what happened to him. On their way back, Soran is invited to a party by Rikukin's granddaughter Riku Rinron
Soran has opened up to the other young outsiders, but his next opponent uses Toumon, the style that killed his grandfather. As the tricks he's been using will be ineffective against this opponent, Soran demonstrates the true power he's kept hidden inside himself. Meanwhile, Houhou struggles against Shoushou. While watching her match, the Tenshi and Rikukin begin to realize there's something about her that makes her different from ordinary outsiders.
While struggling against Shoushou, Houhou recalls Niken's words and begins her counterattack. Ouya and Shokatsu Sei's match is next. Shokatsu Sei has realized Ouya is a fangshi and Qimen Dunjia user like himself. During their match, Ouya encourages Shokatsu Sei to stop fighting and admit defeat, but...
Determined to know the truth, Shokatsu Sei uses his Qimen Kenzou Shinpou in an attempt to discover the secret behind Ouya's mysterious and powerful Qimen Dunjia. His is one of eight secret arts: Fuukou Qimen. Later, Fuu Saen faces off against Ja Seiryan. The match quickly turns hostile when an impatient Saen destroys Ja Seiryan's phone, interrupting his phone call.
The match between Fuu Shinton and Tou Yuufuku is a showdown of summoners. Meanwhile, Ouya is nearly buried by Houhou at Soran's request, and arrives at the arena just before his match is declared forfeit. However, Ouya makes a surprising suggestion to Soran.
Soran decides to continue seeking the truth. Ouya respects his choice and forfeits the match, thus ending the battle between them. Next is Fuu Saen and Houhou's match. Fuu Saen forfeits, and Houhou advances to the semi-finals. Finally, in the match between Fuu Shinton and Elder Ou Ai's great-grandson Ou Hei, both combatants use Kourei Kenshou. Only members of the Fuu family should know how to use the secret art of Kourei Kenshou, so how is it that Ou Hei is able to use it...?
Ou Hei attempts to use his Shokurei ability to steal Fuu Shinton's treasured spirit Ou Shichuu from him. Shinton makes the difficult decision to let Ou Shichuu's spirit pass on and loses to Ou Hei. Chou Soran, Fuu Houhou, Chou Reigyoku, and Ou Hei advance to the finals, and the tournament nears its end.
The final round of the Raten Taishou pits Chou Soran against Chou Reigyoku. Losers Shokatsu Sei and Ouya begin leaving Ryuukosan and heading now. On the day of the finals, Reigyoku receives encouragement from his master the Tenshi and his fellow disciples. Meanwhile, Fuu Houhou tells Soran he hopes he wins the Raten Taishou. In order to learn the truth he and Houhou carry, Soran heads into the final match against Reigyoku.
The rollercaster final between Chou Soran and Chou Reigyoku continues, which has become a contest between Soran's positive power Yougorai and Reigyoku's negative power Ingorai. However, when Reigyoku uses Suizourai, Ingorai's true form, Soran struggles. Enveloped by Reigyoku's Suizourai, Soran recalls the lesson he learned from his grandfather Chou Shakurin as a child.
Chou Soran appears to have defeated Chou Reigyoku when he uses his ace in the hole. However, Reigyoku gets back up, and Chou Soran prepares himself for defeat. Then Reigoyku's body begins acting strangely... Meanwhile, at Rikukin's orders, Tsuu Kinka and Riku Rinron guard Ryuukosan against an attack from Zensei. However, there's no sign of the organization.
Having won the Raten Taishou, Chou Soran attempts to learn the Way of the Tenshi from the Tenshi. Meanwhile, Zensei finally appears on Ryuukosan and attacks the Tenshifu. The Tenshifu's monks struggle against Zensei's overwhelming numbers. Chou Reigyoku is surrounded by Zensei leader En Tou and his underlings. That's when Rikukin and the feiends he fought during the Raten Taishou arrive.
Rikukin takes over for Reigyoku in his fight against Zensei leader En Tou, forcing him to retreat. However, Ryuukosan is swarming with Zensei thugs, and the battle isn't going well for the Tenshi.
Ryuukosan is danger, and the Tenshi finally makes his move. Meanwhile, the tables are turned on Rikukin and Chou Reigyoku when Zensei's Four Sorcerers appear. The cornered Rikukin amplifies his rage to its limit and begins running out of control. All-out battle breaks out between the forces of Ryuukosan and Zensei!
The Tenshi prepares to sacrifice himself in order to return the rampaging Rikukin to his senses. Meanwhile, while searching for Houhou, Soran spots Riku Rinron and Tsuu Kinka, whose lives are in danger. Will he save the girls who are surrounded by a large group of Zensei members? But he must find Houhou as soon as possible! What will Soran do...?
While saving Riku Rinron and Tsuu Kinka, Soran kills a person for the first time in his life, reminding him of the value of human life. Meanwhile, Zensei members Baron and Ryuusei stand in Houhou's way as she searches for Soran. What is their purpose...?
The battle between the Tenshifu and Zensei is over. While the Tenshifu was able to drive back their enemies, both sides suffered heavy casualties. However, their troubles are far from over.
The Tenshi's servant Hane is actually Kyoukei, acting Master of Zensei, who believes Den Shinchuu possesses an important secret concerning the Koushin War. He reveals that he hid his identity to get closer to Den Shinchuu and planned this attack so he could acquire that secret. However, when Den Shinchuu refuses to talk, Kyoukei summons Meikonjutsu user Ro Ryou and tries to steal Den Shinchuu's memories.
Den Shinchuu's death leaves Chou Soran and the members of the Tenshifu overcome by sadness. As the sun rises, news of Zensei's attack on the Tenshifu spreads throughout outsider society in the blink of an eye. Meanwhile, Ouya has been expelled from the Butou style and is heading to his home of Beijing alone, followed by mysterious figures. Finally, dark clouds appear to be gathering over Butousan, home of the Butou style.
