Yuri was one of the four White Alligator members hired to transport the comatose Saitou Souta while Misaka Mikoto and Aizono Mio were distracted by a rumour leading them into a trap, though she and the others had the secret goal of getting revenge on Souta and Mio, jealous of her being the only White Alligator member saved by the counselor. While the other three faced Aizono Mio, Yuri made sure Mikoto asphyxiated in their oil trap, but Mikoto managed to survive due to using her virbrating iron sand to break down the oil surrounding her into oxygen, nitrogen and other components of air and bringing those to her mouth. She was defeated by the Level 5 and was last seen being carried out of the oil pit by Mikoto.
