The gang tell Kurama that he can't fight anymore in Maze Castle because Genbu injured him too badly. Kuwabara says he will be the next to fight and ignites his new and improved Spirit Sword. He doesn't need to use the wood from the enchanted sword anymore and he can change the length of his new sword.
Botan calls Yusuke over the Communicator and tells him that the Saint Beasts have launched another wave of Makai insects and that the people of Earth are becoming increasingly violent. Botan then gets chased by a possessed male human and was barely able to escape the ferocious blows of the zombie-like possessed human and knock him out.
Maze Castle begins to crumble around our heroes, thanks to the workings of Byakko. They race for their lives and reach the outside where Byakko is waiting for them.
Byakko destroys most of the platform they are walking on, only leaving a bridge to cross to his platform. Kuwabara crosses the bridge to fight Byakko.
Byakko pulls out four strands of his hair and blows on them. Four smaller tiger-like monsters emerge and attack Kuwabara. Kuwabara uses his Spirit Sword and still it is not enough to escape the tigers' attacks. Yusuke wants to help Kuwabara, but Kuwabara won't allow it. Yusuke then talks some sense into Kuwabara and he runs back towards the others.
The tigers follow Kuwabara as he runs across the bridge towards the rest of the gang. Suddenly, Kuwabara turns back around and lengthens his sword, shish-kabobbing all the tiger creatures. The tigers then begin to run at Kuwabara, even with the swords piercing thhrough their otherworldly bodies. He leads them around a tower and locks them together.
Byakko gets mad and destroys the tower and the tigers he made. Byakko then steps up to fight Kuwabara. Kuwabara makes another Spirit Sword. Byakko can smell Kuwabara's fear, which in turn, angers Kuwabara and he attacks Byakko. Kuwabara begins to get weaker with every move he makes. He then notices that Byakko is growing, and it is because of Kuwabara's Spirit Energy. Kuwabara doesn't want to give up and continues to fight on. Will he survive against his own energy when Byakko attacks?
