Still Mina held the journal like she had when she smacked the weird creature away, prepared to hit it again if she had to. However, that was when the red haired man made his way into the scene. She observed quietly, as she always did in situations she was in trouble and someone managed to intervene, wondering what the thing was that was now caught in Isaac's hand. However, this left her mind as she squeezed it until it popped out of sight, whether dead or fleeing. It still startled her into a tiny jump, shoulders bunching up closer to her jawline.

"A-ah..." Mina considered a moment a response, before straightening somewhat to try and appear relaxed. "I... thank you." Well, he did get rid of it, even if he hadn't really intended to assist her or not. She was so weak... she'd have to talk to Soma about teaching her how to fight.
