Plot
Minamoto no Yorimitsu and his four generals, including Watanabe no Tsuna, and defeat the demon of Ōe-yama. Later, one night at a banquet, Yasumasa tells of a servant of the Ōe-yama demon, Kidōji that is menacing passers by at the Rashōmon. Tsuna, expressing doubt, visits the Rashōmon to verify the rumour, and cuts off Kidōji's right arm with a tachi called Hizamaru (膝丸), but as he is returning with his prize the demon steals his arm back. Later, Yorimitsu falls ill. Hearing that his master's sickness will be cured if the demon who lives in the forest of Uda, Yamato Province, Tsuna heads out. He encounters an ushi-oni in the form of a beautiful woman, cuts off its hand with a tachi called Higekiri (鬚切), and carries it home.

On the advice of a fortune-teller, Yorimitsu places the hand in a red chest (朱の唐櫃 shu no karabitsu), placing the chest in a northwest-facing storehouse. He encloses it in a shimenawa and for seven days reads aloud the Humane King Sutra before it. On the sixth day, the ushi-oni appears before Yorimitsu in the form of the latter's mother, in order to steal back its hand, but Yorimitsu cuts it down with Higekiri.

The swords Hizamaru and Higekiri are dubbed, respectively, Onimaru and Onigiri and become prized family heirlooms of the Minamoto clan.
