A succubus who suddenly appeared, claiming to be the protagonist’s older sister. She possesses an incredibly alluring figure. She boasts that she will grant him every pleasure he desires in exchange for returning her to her original world, and is draining his vitality as she pleases. Although she gives off a gentle, laid-back impression, her personality perhaps befitting a demon is extremely domineering and self-centered. [From official site]
