A student at a mid-level university. Recently started work at a tutoring center.

♀ f

Tomoka is skilled at sports, but her low intelligence made her a target of mocking from the boys in her class. She's not good at studying, but tries her best. She's shy, but also very energetic.

♀ f

The protagonist's sister, who loves her brother very much. In fact, she secretly wants their relationship to go past being mere siblings. When Takayuki becomes her tutor, she's very happy about it.

♀ f

The daughter of a rich company president. An ojou-sama who was raised without even having to use chopsticks, she relies on her maid Rion to take care of her. Natsuyu goes to a very prestigious school, but she never takes notes, which makes her grades poor.

♀ f

A maid who takes care of Natsuyu. Rion is a high-spirited and very loyal (to Natsuyu) person. Although she's the same age as Natsuyu, she was raised as a maid since she was very young, and hasn't had the chance to go to school. Her catchphrase is "I'll with enthusiasm!"

♀ f

The shy yet serious class president. Even though she's an honor student, Haruka is also an otaku, who likes to cosplay and has even been trying to draw her own manga. Because of this she's neglected her studies lately, and her grades have dropped.

♂ m

Haruka's little brother. A very pretty boy who's often mistaken for a girl. Fell in love with Takayuki very quickly after being tutored by him. Despite being a boy, he has a very androgynous atmosphere about him.

♂ m

Withdrawn from school due to an illness, Yuzu is now being tutored by Takayuki. Due to being so small and weak, Yuzu spends most studying time on the bed and only wears pajamas. Seems very much like a girl, but has a certain something that girls don't usually have.
