Hakumenrou

Hakamenrou (白面郎): Armored mystery man who turns out to be Tsuruhime's father. He resurfaced with Daimaou during Daimou's eventual coming in the human world, leaving his daughter at a young age in an attempt to stop it from happening. However, he failed and offered his servitude to Daimaou in return for the lives of his companions. However, Hakamenrou used his servitude as a ruse to side with the Youkai in order to find Daimaou's weakness. Upon arriving to oversee the final steps of Daimaou's arrival, Hakamenrou is forced to fight his own daughter to keep face. It was by the Daradara incident that Daimaou learned the true intend of Hakamenrou and turned him to stone for his betrayal. Yama-uba tried to use Hakamenrou as her trump card, but he was restored by the series' end and reunited with his daughter.
