But Ard knowing her for more than 3,000 years, actually can be also a different person from what people did expect.

According to Ard, when she is in a sour mood, she became a peppy little chatterbox. On the other hand, when she was happy, she’d zip her mouth tighter than usual and play childish pranks on you. Oh, and it was completely possible to guess her thoughts at any given time by observing her cat ears and tail.

She is a sharp person who suspected that Ard is the reincarnation of the Demon Lord at first sight. Being his older sister figure from the old days, she had been harsh with him but also kind to him.

Though being a calm person, she can lose her cool shown when Ireena asked about his father since it was rare for others to interact with her with such blinding innocence and naïveté like of Ireena's.

Unconditionally, she loses her thinking with it comes to sweet potatoes making her more child-like. This was also a reason that she wants to punish the demon lord because he ate it.
