Even when there’s nothing there she trips and falls.

When she was younger, anytime there was a problem her older brother helped her so she is rather pampered.
She relies on her older brother so much that she believes that what he says is completely true to the point that when he tells total lies she totally believes him.

This timid Hiyori has no experience in sex, but is rather curious about it.

When her parents are away, she boldly tempts her older brother with sexual advances. It’s an established fact that she always outmaneuvers the others.

Multi-skilled, she participates in both the tennis and swimming clubs. Due to that, she always eats a lot, but unfortunately none of those nutrients go into her chest.

### Nanase Michika (七瀬 みちか)
Brotherly term of endearment: "Nii-sama"

A little sister who shows very little emotion. Her expression generally doesn’t change.

She appears to love books as she’s always seen walking around with one. Her room is filled with books.
She’s a bookworm whose thoughts can’t be read.
But if there’s anything sexual going on, she goes after the protagonist relentlessly.
This is her way of expressing affection. Believing in the absurd information she read in a book that said, ”In order to become lovers with the person you love, it’s best to train your target,” her aim is to make her older brother her own.

From what she learned in books, she’s a skilled technician who, when serious, can make you ejaculate till you faint in less than a minute using fellatio, hand jobs, and other techniques.

### Nanase Rio (七瀬 理央)
Brotherly term of endearment: "Aniki"

She is the stern little sister who watches after the studies of the others.

Completely unaccustomed to anything related to sex, she’s a late bloomer in that subject matter.
Whenever her female siblings start to talk about anything lewd, she totally gets red in the face.

Whenever her older brother is in front of her somehow or another she’s always angry at him.
... Though that is the attitude she takes, she actually really likes her older brother.
She tries her best to show those feelings of love towards him, but before anyone knows it, she hits him with an elbow.

A typical tsundere who can’t be honest with herself.
