Tōga

Intro no Taishō (犬いぬの大たい将しょう, "Great Dog General") or Inu no Daiyōkai (犬いぬの大だい妖よう怪かい, "Great Dog-Demon"), was a powerful inu daiyōkai who was known quite well and feared throughout feudal Japan as being the very strongest of his kind.[2] He fathered two sons, the firstborn of which was the powerful inu daiyōkai Sesshōmaru, mothered by a female inu daiyōkai, his first wife, but their relationship did not work out. His second son was the inu hanyō Inuyasha who was born from the human woman Izayoi, Tōga's second wife. Tōga had many adversaries during his lifetime, and many of them have ended up crossing paths with one or both of his sons and granddaughters a couple centuries later.
