Ushi Gozen

Ushi Gozen is the Rider-class Servant summoned by Yui Shousetsu in the Waxing Moon Ritual of Fate/Samurai Remnant. Minamoto-no-Raikou summoned as a teenager, the time of her life when she was a monster. The period where she was a guardian of the human realm and weapon of apparition slaughter devised by her father Minamoto no Mitsunaka, before she had any of the emotions of a human girl. In this state, her True Name is Ushi Gozen. Her reason for responding to her Master's summons is the doubts and empathy towards the world's distortions that come with being a non-human in the shape of a human. But tragically, the only answer she could find to her questions was destruction. No matter how many times she is summoned, she won't change her mind. Ushi Gozen initially pretends to be Raikou, even going so far to tell her own Master that she is Raikou. Under this act she is devotedly loyal to Yui Shousetsu, as well as cold and ruthless toward her enemies. Ushi Gozen drops the charade once her armor is destroyed by Saber, after which she often breaks into mad laughter and demands that others worship her divinity. She wishes to fulfil Yui's wish of fixing the world, but interprets it very differently than how Yui does: Ushi Gozen plans to "fix" the world by destroying it.
