Ursula Aquinas Rescue arc
During the rescue of Ursula Aquinas she, along with three other Amakusa Catholics, encountered Kamijou Touma, Index, and Stiyl Magnus shortly after they entered Parallel Sweets Wonderland. After Stiyl escaped from the area with Index, the other three Amasuka members ran after him while Uragami stayed behind to defeat Touma. Touma began to run away from her and eventually was running between a small gap between two shops where he tripped over some tools. Once she caught up Touma quickly grabbed a toothpaste tube-like object and threw it at her. When she cut the tube the sword became covered in a substance which turned out to be grease for machinery. This greatly reduced how sharp the blade was and when she swung it at Touma and hit his wrists it did not cut him. Before she could react to this he slammed his entire weight into the her chest and knocked her unconscious. Before she hit the ground he protected her head and laid her on the ground. Before leaving he grabbed her sword and dragged it along with him for she couldn't use it when she woke up. When Tatemiya encountered Kamijou Touma he noticed the sword and asked if he got it from Uragami.
