Summary[]
As Ren attacks Tao Yúan, he seems to hit him but suddenly Yúan disappears and appears again at another spot. Yúan then grabs Ren and throws him against the wall. As Horohoro attacks Yúan, the same happens and he gets smashed to the ground. As Ryu attacks and thinks he hit Yúan, he comes falling out of the air all of a sudden and crushes Ryu. As Yúan defeats Lee Pyron as well, he states that Ren became weak because he cared for others now. As Yúan gets angry and starts attacking Yoh, Ren is able to save him by stabbing his father. As Ren cuts off his father's head, his father's body beats him to the ground again. As Yúan wants to kill Ren, Yoh is able to block the attack but takes another blow himself.
As Ren makes a stand together with everybody, the symbol on his back finally disappears. As everyone attacks Yúan, Ren is able to hit him with a Chuuka Zanmai attack. As Ren attacks his father again, it's revealed that the big Yúan they where fighting, was, in fact, Yúan's Over Soul. As his Over Soul has been disappeared, the "real" Yúan shows himself. Yúan then tells about the Tao Family's history, and how they were detested and kicked out of the capital. As Yúan tells his son Ren that he should not forget about their history, Ren states that he is indeed a member of the family, but also that he is his own self. As Yúan attacks with all his Furyoku, Ren is able to defeat his father with his big Over Soul. As Yúan states that it's not over yet, just then Ren's mother and grandfather show up and state that the fights are already done.
Later on, everyone is enjoying a very nice Chinese meal together. Meanwhile, Yúan is outside wondering about what happened and thinking about Ren's choices. Later on, as Yoh and the others are traveling back, Ren is seen traveling by himself. As Ren is riding his horse, his father shows up and gives him Bâo-Lèi Sword, a sword that has been passed down to the Tao Family from generations. Later Yúan then wishes his son Ren good luck.
