リディア=ルイトガルト

Yggdrasil Magical Academy First Year
Class: Succubus 

A first-year student at Yggdrasil Girls' Magical Academy. Lydia is unusually timid for a succubus, and hopes to improve her social skills her—as well as her skills her in the bedroom—in order to live up to her mother's expectations.  

To become an even sexier succubus, she decides to ask the protagonist, the only male student at the academy who has just transferred in, to help her with her “training."

Her cute, round face, not unlike that of a small animal, rouses his protective instincts, and her S-cup breasts, almost unbefitting of a first-year student, could turn out to be a lethal weapon!
