Elise held her sword with both hands and her eyes locked on the younger-looking girl, who turned out to be a lot more patient than she assumed. It caught her off-guard a bit.

This girl wasn't just talking for show, she meant what she said. She was confident, and Elise respected confidence like that. 

She made her sword disappear. She decided to go along with her, not because she was afraid of the girl, but because she was honestly intrigued at the chance of meeting other magical girls she could pick a fight with. Maybe one them will.
