Description
The character referred to as Père d'Inu-Oh, or simply Inu-Oh's father, is a supporting antagonist in the animated film INU-OH. He is never given a personal name in the story and is identified only through his relationship to the protagonist.

His background is shaped by an ambition for artistic greatness that leads him into a dangerous bargain. He is the leader of a sarugaku, or Noh dance, troupe in Kyoto during the early Muromachi period of 14th-century Japan. Seeking to improve his art, he obtains a demonic Noh mask with magical powers. Under the mask's direction, he murders biwa players who perform their own versions of the Tale of the Heike, using the mask's magic to seize their songs as his own. When he desires still greater mastery, the mask demands a price: his unborn child. The father accepts, and the transformation inflicted on the fetus leaves the child, Inu-Oh, born with a severely deformed face, three stubby limbs, one greatly elongated arm, and skin covered in scales. Inu-Oh's mother suffers greatly during this process and dies after giving birth to him standing up.

In personality, the father is gruff and consumed by his pursuit of fame and perfection in performance. He is tormented by his son's disability and regards Inu-Oh with contempt, forcing him to wear a gourd mask to conceal his face, treating him like a dog, and excluding him from the family's artistic training. He is also envious and possessive, and when Inu-Oh rises to popularity, the father burns with fierce jealousy that his son, rather than himself, is the one performing before the shogun.

His central motivation is the desire for renown and mastery in the performing arts, which he pursues without regard for moral limits. He is willing to kill rival musicians and to sacrifice his own child to gain magical power and acclaim.

In the story, the father serves as one of the primary antagonists and the origin of Inu-Oh's suffering. His deal with the mask explains why Inu-Oh was born deformed and why his family rejected him. Late in the film, agents of the shogun Ashikaga Yoshimitsu approach him and offer him fame in exchange for sabotaging his son's performances. During the climactic performance before the shogun, Inu-Oh's dancing reveals the truth about his origin. The father orders the mask to destroy Inu-Oh, but because the child had already been given as payment, the request violates the terms of their pact. Refusing, the mask instead kills the father with its magic, and he disappears.

His key relationships define his arc. With Inu-Oh, he is openly hostile and cruel, seeing his son as a source of shame rather than a family member. With the demonic mask, he forms a pact in which he gains power over the songs of murdered biwa players but eventually loses his life when he breaks the agreement.

His development follows a downward course, from an ambitious troupe leader, to a murderer who steals the works of others, to a jealous father, and finally to a victim of the supernatural power he cultivated. His death removes the curse that marked Inu-Oh and allows the young performer's face to be restored to that of an ordinary young man at the end of the shogunal performance.

In terms of abilities, the father is an experienced sarugaku practitioner, but his most notable powers come from the demonic mask. Through it, he can kill biwa players with magic and absorb and perform their songs as his own, allowing him to amass a repertoire that does not truly belong to him.
