Shortly after Yukari grabbed the briefcase, she heard someone arrive. Two voices stood out, it was Saki and Nadeko! She doesn't exactly remember what either of their quirks could due, since she never saw it. But from what she could infer Nadeko could control metal and Saki had some powers related to electricity. Yukari thought this would be easy until she heard Saki bound forward with amazing speed and even jump over Yukari. "Fast!" Yukari felt Saki's foot connect. On a normal girl this would've knocked them out cold easily. But Yukari was far from normal. Even though Yukari's head hit the ground she was able to stay on her feet as he neck stretched from the force of the blow. By the time Saki got back on her feet Yukari was able to take the force of the kick and literally bounce it back right at Saki. Yukari would deliver a devastating headbutt right towards Saki's chest.
"Two-on-one huh? That's a fair fight!" Even though she said this Yukari knew she had to get away fast. Using her extreme flexibility Yukari snaked her arm underneath Saki's tail and pulled the briefcase up to Yukari's shoulder. She'd tried to slip away as fast as she could, taking advantage of her rubbery body to bounce up onto the rooftops and put as much distance between her and the other two girls as she could. Yukari knew Saki was fast and if she doesn't get away from Nadeko she could easily use her powers to take the briefcase, so Yukari needed to give them the slip. "If I climb up to the rooftops, Acion might be able to spot me and help me out. If not, I can still safely fall from a big height but I doubt those two can, so they'll have to go down more slowly." Yukari thought as she extended her legs out to jump from one building to the next, even across the ruined streets.
