She's the Vice-President of the Student Council and basically Souna's right hand—their dynamic mirrors what you see between Rias and Akeno. As far as popularity goes, she ranks fourth among the school's girls, which makes sense given her skill and presence.
In combat, she's legitimately impressive with a sword. During the Rating Games, she faced off against both Yuuto and Xenovia, with mixed results. She managed to beat Xenovia, but Yuuto was another story—he outclassed her in pure swordplay, so she couldn't rely on technique alone to take him down.
Her Sacred Gear is Mirror Alice, which has a straightforward gimmick: it doubles incoming damage and reflects it back. The catch is she can't activate it twice without a cooldown period in between, so it's not an infinite shield.
