Taigokumaru

Taigokumaru is the leader of the demon bat clan, a ruthless demon who cares very little for others. He appeared in the manga in chapter 214 and in the anime in episode 73.

In his past, Taigokumaru's son, Tsukuyomaru, fell in love with a human woman which angered Taigokumaru greatly to the point that he killed his own son. After that he realized that the human woman was carrying his grandchild and made a deal to protect the woman's village if she gave him his grandchild, Shiori since he needed an heir to continue maintaining the bat barrier. Eventually, the village gave Shiori to Taigokumaru, but he later he broke the deal and attacked the village. Inuyasha intervened, saving the village, however, during the battle, Inuyasha could not hurt the bats due to Shiori's barrier. However, when Shiori found out that Taigokumaru had killed her father, she forced him out of the barrier, allowing Inuyasha to kill him. Even then, his spirit came out of Shiori's crystal and attacked her but he was stopped, and permanently defeated, by the spirit of his son.
