Yggdrasil Magical Academy Second Year Class: Witch A second-year student at Yggdrasil Girls' Magical Academy. A childhood friend of the protagonist, she used to live in the same world as him, but moved to another world due to her mother's job as a witch. Her cool, charismatic beauty and perfect grades make her one of the most popular girls in the class, but her foul mouth and occasional dumb jokes may come as a surprise. Erena specializes in dark magic, and doesn't hesitate to activate it whenever the protagonist brings up any embarrassing anecdotes from her past. Despite being a witch, she's actually not very good at flying on her broomstick, because she tends to get distracted by the friction between her legs...

Yggdrasil Magical Academy Third Year Class: Archpriest A third-year student at Yggdrasil Girls' Magical Academy, and a member of the healthcare committee in charge of the other students' physical examinations. Her family runs a primary school as well as a church, so she has a strong sense of compassion and faith, and she specializes in healing magic. Catherine is a real stickler for the rules, but she can get surprisingly bold with her “confessions.” A gentle and caring girl, she loves doting over the protagonist like a little brother. When her motherly instincts are roused, and during certain times of the month, she produces copious amounts of milk. Inexperienced when it comes to romance, she often turns to her classmate Kaguya for relationship advice.

Yggdrasil Magical Academy Second Year Class: Vampire A haughty, slightly delusional vampire, who gets upset when others call her “Kash-tan.” A typical airhead, she harbors a strange obsession with the protagonist, declaring herself to be his rival as soon as he shows up. Kashnia fears nothing, and often gets herself into trouble trying to fight monsters that are more than she's able to handle. Despite her recklessness, she's always ready to help a person in need, and she's like a reliable older sister to the younger students. As a vampire, she naturally hates crosses, garlic, and holy water, but they don't kill her. Instead, they merely seem to cause her to go into heat!

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!

Yggdrasil Magical Academy First Year Attribute: Magic Dragon A member of a magic dragon tribe, she adores the protagonist because he once saved her life in the distant past, when she was injured and accidentally wandered into his world. Ever since that day, she has been unable to forget about him, and feels like it was destiny that he reappeared before her at the academy. Her name her was given to her by the protagonist, because when he found her, her cries her sounded like “Myau, Myau,“ and she has kept that name ever since. She always tries her hardest to help him in whichever way she can, doing his cleaning and laundry for him—though she may have ulterior motives for taking care of his laundry. Myau absolutely loves sweets, and works part-time at a maid café while studying magic at the academy.

Yggdrasil Magical Academy Second Year Class: Dark Elf The president of the protagonist's class at the academy. Unlike the typical Dark Elves that you may imagine, she's surprisingly diligent as a student, and pure and naive when it comes to matters of the heart. But she does harbor one dark secret... On the day of her ovulation, she goes into extreme heat! She usually skips class on those days... As a prideful elf, she believes that all human men are perverted trash, and bears a deep hatred towards them. Her caring personality tends to attract the friendship of the clumsiest girls at the academy, so she always has her hands full looking after others.

Yggdrasil Magical Academy First Year Class: Battle Homunculus A first year student at Yggdrasil Girls' Magical Academy, she enrolled into the academy to improve her magical combat skills. Her main weapon is a magic gun, and she can harness the power of the Philosopher's Bone to transform into a bodysuit that can be worn by anyone she wishes to protect. However, this skill has a side effect: it's highly arousing to the user! The close skin-to-skin contact causes her to be in a constant state of titillation—her breathing grows heavy, and it makes her heart race. While she looks like a normal girl, she's a very serious student, and due to her shyness, she's often unable to resist the protagonist's forceful demands. Even when her magic power runs low, she'll continue her "training" with him in order to keep her arousal in check.

Yggdrasil Magical Academy Third Year Class: Moon Princess A third-year student a Yggdrasil Girls' Magical Academy, she transferred from the Moon Kingdom to learn magic. Having lived a sheltered life until transferring, she's incredibly curious about worldly matters. Her passion lies in developing magic potions, and she's aiming to earn her formal qualifications at the academy. Aphrodisiacs are her specialty, but she sometimes makes mistakes while experimenting with them on herself. Perhaps because of this, she can become overstimulated, and it takes a lot more than some caresses to get her going. She tries to act like a strong, dependable sister in front of the protagonist, but she sometimes also reveals her cuter side, getting sulky when he doesn't give her enough attention.
