Description

I am Tachibana Eiji, a regular transfer student. Everything was going fine at my new school, but I was in for a shock one day when I discovered the class president Rumi and my classmate Natsuki having sex in the school infirmary! Not only that, it turned out that Rumi was a futanari - a hermaphrodite with something between her legs I wasn't expecting to see. That evening when I got home and got a call from Rumi to come and meet her, I knew it couldn't be good - but the first thing she said was, "won't you join us?"

According to her story she'd been a futanari from birth, and because of this had an unquenchable curiosity regarding the ways of sex. She'd gotten to the point where having Natsuki as a sex partner wasn't enough... she told me she was planning to train our classmate Shizuko as a sex slave! Shizuko, a neat freak famous for her disike of her male classmates, had let it slip to Rumi that she was secretly very curious about sex as well...

Faced with no other options, I had no choice but to accept Rumi's request to join her and her comrades in their erotic schemes... and from that moment I was bound to these cute and "ecchi" kitties in their catgirl alliance!

Description

Modest and nondescript, Eiji Tachibana is the unlikely protagonist of the game. A recent transfer student to his school, his lonesome life becomes convoluted when his curiosity leads him to become apart of a sexual, underground student group disguised as a harmless club. Despite his careless behavior, Eiji is an honest, friendly and especially introspective person, able to sense the mood of other people; though he himself is as easily readable. Eiji prefers the indoors and enjoys watching television.

Description

Eiji's classmate. She sits next to him in class, and seems like a kind enough person. Due to trauma suffered in a sexual harassment incident in the past she became an obsessive-compulsive neat freak, and was violently ill-disposed toward members of the opposite sex; recently she has largely recovered and is fine with men around. Her personality has a cool and high-handed side, but once she takes to someone (boy or girl) she becomes quite intimate. Regarding sex she knows what she's read in magazines and heard from the idle chatter of other girls, which sparked her interest in the subject. She has many hidden interests in this area, which it's up to Eiji to find out!

Description

Eiji's classmate. Taken into Rumi's family by her father as a child, Natsuki was raised as his second natural daughter. However, her fierce devotion to Rumi has given her the appearance more of her maid than her sister. At a glance she's the inscrutable, mysterious type. She doesn't talk much and doesn't let her emotions show, but due to the development of her body at Rumi's hand when she enters "H" mode she undergoes a complete change, to a brazen, dirty talking girl. Because Rumi has focused on her anal training, Natsumi is still a virgin. She alternates between sadistic and masochistic personalities at Rumi's command. She is initially discontent with Eiji and his blossoming friendship with Rumi, viewing it as a rivalry; over the period of her acquaintance with him however, she grows fond of and closer to him herself. Given her openness to partners, Natsuki is also bisexual.

Description

The president of Eiji's class. A bright, high-spirited and popular girl, her father is a newly rich self-made man and her family is tremendously wealthy. Thanks to her personality this upper class "princess" status of hers doesn't particularly show, though. Born as a futanari, she got over her dislike for her body at an early age and came to be curious about all things sexual. With Natsuki as a partner she's been researching her sexuality almost nightly in the school infirmary. While already fully sexually experienced, she is constantly in search of further stimulus and pleasure. While Rumi is a naturally effervescent and outspoken co-ed, she can at times be particularly authoritative, sadistic and intolerant, especially during group activities.

Description

Rumi's step-brother, a year younger than the protagonist. His frail constitution, slender build and pale skin make him look remarkably girlish. In love with his sister, in the past she caught him stealing her panties to use for dubious purposes and since then has been blackmailed into her service. He is now at her beck and call in her quest for sexual stimulation. He's still a virgin in all senses of the term, but is experienced in "petting level" play along with Natsuki and Rumi.
