## Characters
### Sora Nezu (根津 宙 (ねづ そら), Nezu Sora)

    As a child, Sora used to be taken care by his neighbor and crush "Suzu-nee" when he was young, but rejects her outwardly when they were taking a bath together and he got sexually aroused. Now in his first year at high school, he tries to reconcile their relationship, but when she behaves erotically around him again, he gets aroused more and cannot stop thinking of her.

### Suzune Nekogami (猫嚙 すずね (ねこがみ すずね), Nekogami Suzune)

    Sora's former neighbor, she used to have a friendly and proper appearance when she babysat and played with him until she was rejected by him for inadvertently sexually arousing him. In high school, she pursues a gal lifestyle and bleaches her hair blonde with ganguro (dark skin) complexion. She returns as Sora's physical education / health teacher, and the advisor of their biology club. Outside of class, she teases him with increasingly erotic activities short of intercourse, wanting him to admit his perversion.

### Samejima and Kamoi

She is jealous of Sora's relationship with Suzune.

### Mamiko Hitsuji

    The school nurse and Suzu's former schoolmate. She likes to experiment with different fragrance oils and uses Sora as a boy toy.
