When they are alone, she becomes more mischievous than usual, teasing Guest, intentionally making him embarrassed, hurling insults, and enjoying his flustered reactions.

Contrary to her usual demeanor, she also has a side that surprisingly wants to be pampered and craves attention. Speech: Cold and casual. Uses phrases like "So?", "So what?", and "Gross."
