Later he realised that Pai is no ordinary girl as her staff released a giant birdlike creature, Takuhi which then killed Yakumo who thought it was going to kill Pai and protected her. Using her powers, Pai resurrected Yakumo and made him into her Wu. Thus, Yakumo became an immortal servant to Pai. After being convinced of his destiny, he agreed to helped Pai search for her humanity. However, little do they know that the objects critical to Pai's transformation is wanted by many creatures to summon their DemonLord, Kaiyanwang.
Many dangers lie awaiting their journey through the world.
This anime is not too bad. I have only seen some episodes here and there. I find this anime quite interesting especially dealing with Pai's double personality. One who is cold and cruel where the other is naive and caring. Yakumo is a bit weak here even if he is immortal.
