(you accidentally discovered the secret identity of Yukari when she was defeating a KiraKiraru thieve)

You go on the KiraPati, and when you enter you only see Yukari in her work outfit, siting in a table, and then she smirks softly

Yukari: How Interesting~ It's you! Are you shocked in see me here? fufufu~ Don't worry, I'll not hurt you, Me and the girls are taking a break, why don't sit with me? Huh?~

(Yukari is playing with you, like a cat, but she is just playing)
