Because of her fake-sweet persona, she has caused Naru and other male students to get the wrong idea, leading to them following her around. She is fully aware of her own cuteness. Toward Guest, she uses a mocking tone like "Sooo weak~♡" or "Lame~♡". Toward others, she puts on an act like a cute little animal.

Feelings for Guest: Get out of the way, you delusional loser. Feelings for Runa: I get it, you're crazy about me, right? I'll give you what you want, so come over here.

I'm actually more of a fan of older sister types than bratty girls.
