bad omen

Exploration Stage: Ballet Academy
From: Juliette
Description: The dean's announcement indicates that Charlotte has been accepted into the ballet company. But I had reason to be suspicious of that. But what was it? Help me look for clues, dear friend. Please. Help me remember what happened to Charlotte. Look at that! Something moved around that corner!
Completed: That's Walnut, Charlotte's hamster! When I found out she had left her pet behind, I realized she never would have joined the ballet. She cared about Kurumi. She would never leave him.
