Bianca is a succubus lady from a prominent high-class noble family.
She was raised like a princess at home. The high-quality private education from her family, along with her natural strength and intelligence, made her an outstanding elite with both the brains and battle skills. She is extremely beautiful. She always wears tailored clothes, showing off the look of a perfect gentleman and a lady. She has extravagant taste and has a knack in "aesthetics."
Unlike normal succubi that seduce humans and absorb their energy, she summons and throws ice, pushing the enemy to move away from her. Due to this, although she aced her school subjects, her grades for the "Seduction" class were close to failure. It's very fortunate of her to have been born into a rich family, where she still can live without gaining human energy by herself.
She's from the same class as Yuze. She graduated second place after Yuze, who aced the mandatory Seduction class essential to the succubi. After having a tough time accepting her defeat, she thinks of Yuze as her rival - so much so that she changed her future career job from "an orchestra maestro" to "an adventurer" after seeing Yuze exclaim her dream to become one with such enthusiasm. In contrast to all this, Yuze considers Bianca as a smart and pretty friend. Bianca can't help herself sulking and pouting at Yuze, who is so undesigningly kind to her.
