Tsukuyomaru

Tsukuyomaru was a bat demon and the father of Shiori. He fell in love with a human woman and they had a hanyō daughter together, Shiori. His father considered him weak for doing so. Father and son would later have an argument about this, with Tsukuyomaru having decided to leave his demon clan for the human village where his wife and daughter lived. He would also abandon the hereditary duty of creating a barrier with the red orb. His father's hatred then came to a head and he killed Tsukuyomaru without any remorse, planning to use Shiori instead to care for the red orb.

His last farewell was that he put his arms around Shiori and her mother for protection then turning into a bubble-like soul as he left.

He appears in manga chapter 214 and episode 73 in anime.
