Overflowing with juicy words and with clearly excitable knowledge about sex! However, all that is in order to be a healthy and perfect lover… So begins an undoubtedly pure love story!

Akiho Kousaka

Voice Actor: Aoi Yuuki

Sharp-minded and excellent at sports, a beautiful girl that has a mysterious aura. In order to be a suitable, genuine and legitimate girlfriend for Haruka Shinozaki, she researches the finer points of male-female relationships on the daily. An expert in many (sexual) interests and tastes, her lust for (sexual) knowledge knows no bounds. Her attitude, although one of a definite seeker of truth, is only down to her knowledge.

Haruka Shinozaki

Voice Actor: Mitsuhiro Ichiki

A regular high-school student who walks around in a regular school uniform… He’s that kind of guy. However, because those around him are rather quirky, he has a natural knack for putting them in their place with witty remarks. He’s a good guy who generally looks out for other people and his interest and knowledge about sex is that of a normal high-school boy. However, he feelings towards Akiho are stronger than ten people put together… Apparently.

Shizuku Ariyama

Voice Actor: Rarisa Tako Takeda

Haruka’s childhood friend who is basically like his sibling, she often appears in front of Haruka and aggressively communicates with (sexually harasses) him. However, she’s not good at being forward, and so often gets shot down by surprise counter attacks. She has a huge complex about her not-so-huge chest and takes a lot of damage when she looks at the voluptuous girls around her.

Rina Saijou

Voice Actor: Natsumi Yamada

Haruka’s classmate. The beautiful daughter of a wealthy family, she transferred from a posh all-girls school and is unfamiliar with commoners and gentlemen. She’s a little- no, really out of touch with reality, and her airheaded words and actions mean she’s often manipulated by those around her (mainly Haruka). It’s rumoured that at her previous school she went past the limits of friendship with her friends and had sexual relationships with them, but it’s not clear what the truth is.

Kanada Shinozaki

Voice Actor: Yuki Yagi

Haruka’s younger sister who love love loves Haruka and has a total brother complex. She acts so childish you wouldn’t think she was in high school, and she has the same level of knowledge about sex as an elementary schooler. Despite this, she goes along with the exciting conversations that happen around her and pretends to understand, which troubles Haruka.
