Yue Kaida

History
Many years ago, four prodigious junior cultivators appeared. One of them belonged to the Saito clan, Saito Hiro, one to the Yue Clan, Yue Kaida, one to the Nagisa Clan, Nagisa Gen and the forth was of unknown background, Tanaka Yuichiro.

All three men fell in love with Kaida and confessed their love. Because the Yue Clan and the Saito Clan had previously made an agreement to combine their bloodlines, Kaida was expected to choose Saito Hiro. However, she chose Yuichiro and this caused Saito Hiro to attack the couple while Kaida was pregnant with Yuichiro's baby, Areshi.

The result of the battle was that Gen got injured and Yuichiro had his spirit sealed. An agreement was made that in order for everyone to keep their lives and to avoid a war between the Nagisa, Yue and Saito clans. Yuichiro wouldn't be able to enter Karakura ever again and Kaida wouldn't be able to leave it.
