She was the one who tested Runo. She was originally disguised as an old woman who told Runo where an Illusionary Dan was. When she revealed herself, she outright told Runo to stop being so stubborn, but Runo would not listen.
She almost won using the most powerful Haos ability card, Sagittarius Arrow, but she was defeated after Runo learned to stop being so stubborn and to listen to her friends, and Tigrerra evolved into Blade Tigrerra. The result itself is not seen because when the battle is almost over, Lars Lion says that Runo has learned not to be stubborn.
