School Year: Sophomore Occupation: Student, Accounting (and general affairs) at the Hibikino Shop "That eroge releasing this month we've invested so much into promoting is... wait, delayed?!" Of the Hibikino sisters, she's the most put together and takes care of managing the Hibikino Shop. She still isn't pleased with how Yukari turned their home into an eroge shop, but now that it's a done deal she puts her all into the business. It ends up that she does the most work of them all. She's the same age and is in the class as the protagonist, having been friends from childhood. They got along well back then, but after hitting puberty they've stopped interacting as much.

School Year: Freshman Occupation: Student "Keep it down! Quit it with all this eroge talk!" As the youngest sister who's not comfortable with adult content, she still can't accept their home renovation. Disliking lewd things, she hopes their home can be changed back into a normal store as soon as possible. She's at the age when she wants to try new things, but at the same time she feels the need to oppose her sisters. It's frustrating that she can't do anything by herself. In reality, she doesn't detest her sisters' actions as much as she lets on. It just happens that sometimes she gets brash with her wording. One could say it's the other side of her feelings for her family and the protagonist.

School Year: Gap Year Before University Occupation: Hibikino Shop Manager (Marketing, Product Procurement) "I'm the manager of an eroge shop, you know? Reading eroge during work is just another part of my duties!" The oldest of the Hibikino sisters, she's the eroge-loving obsessive who had their family home renovated into an eroge shop. In contrast to her young appearance, she spews out dirty jokes like you wouldn't imagine. She loves talking about the eroge she likes, and channeled that passion into making an eroge shop. But she left all of the annoying stuff to Tsumugi. Despite being on a gap year after having failed to get into university, she doesn't seem to have any intention of studying.

Favorite series: Cube. Favorite character: Mamiya Yakumo. Rio is a second year high school student and classmates of Kyouya, Takuto and Azusa. She is a terrible gamer, a severe otaku and also a doujinshi author known enough for her yuri works on the characters in CUFFS Story's under the name "Kawai Atsume". Together with Takuto, she is the founding member of a game guild; she wants Kyouya to join it as well. A rather mediocre student, she is nevertheless very involved in her work as an artist, always finishing her work on time. Because of her strong taste for yuri, Rio is often teased by Azusa who tells Nana to be careful around Rio because she could "attack" her at any moment. However, Rio is heterosexual (but that doesn't stop her from making Azusa believe that she would prefer to "attack" her) and she dreams of one day finding a nice boy with whom she can share her passion.

Favorite series: None in particular. Favorite character: None in particular. Takuto is a second year high school student and classmates with Rio, Kyouya and Azusa. He's a pretty hardcore otaku who is in love with 2D girls. With Rio, he is the founding member of a game guild; just like Rio, he wants Kyouya to join it. He talks quite easily with his close friends and other boys but quickly loses his temper in front of girls he doesn't know.
