Oryuu is the humanoid form of Rider's Noble Phantasm, Like A Soaring Dragon.
Oryuu first appears with Rider as Sakura Saber is facing off against Assassin. She fights off Assassin, and they are then confronted by Demon Archer. Although she appears to quickly defeat Archer, she is disabled in a single shot. They manage to retreat with the appearance of the Fuhrer and his army of Servants. They later face off against Archer again, Rider unleashing his Noble Phantasm as Oryuu transforms into a dragon.
Oryuu shows the ability to deflect the blows of a Servant with her bare hands in human form. While able to easily overpower Demon Archer, her level of Mystery allows her to be easily defeated by Archer's Tenka Fubu - Innovation Skill.
