@lolipedofin Well, in this chapter she's disrespectful and rude with that Yaotome-
senpai bit, refusing to call her the club president, then changing from -senpai to -san after beating Ayumu. Even to non-Japanese people she's horribly rude at best, and I would guess that Japanese people would find her attitude appalling. She needs someone to knock that chip off her shoulder, so I'm hoping Urushi absolutely slaughters her at shogi next chapter.
And she's not unique, assholes are a dime a dozen in the real world and in manga. That's the reason the phrase "knock the/that chip off his/her shoulder" exists. Frankly I don't read cute, fluffy series to have to deal with asshole characters, and clearly I'm not alone in that. Those characters have their place, but this really isn't the type of series where they fit in well.
