Beautiful stranger

Exploration Stage: Enchanted Ball
From: Isabelle
Description: I'm glad to see you, Detective. I came here to find you, but once I entered the cafe, a fight started with a dozen beasts... The most awful thing is that they're almost invisible! I study such phenomena, but this was... for the first time... (Isabelle is so weak she sways) I'm sorry, I'm too tired... Could you bring me some water?
Completed: Hot sweet tea - even better than water. Thank you, I don't think we've met before. I apologize, it's so rude of me. My name is Isabelle, nice to meet you!
