The estranged childhood friend
Her mother is good friends with the protagonist's, and this led to them playing together often when they were younger.
Due to various reasons, mainly the protagonist moving, their relationship became estranged,
but now, several years later, they find each other at the same high school, and in the same class this year.
Personality-wise, she has a big heart, and can put a smile on your face just by being around you,
but truthfully she can be quite stubborn if you get to know her.
Himari is never one to go to others when she has a problem, be it guy or girl, but if she sees
someone in need of help, she will always be the first one there.
Contrary to her cutesy, child-like appearance, she is rather strong-willed.
Both she and the protagonist have matured a great deal since their time playing together as kids,
so she can't quite figure out what to say to him now, or how to act around him.
Also make sure you never tell a bad joke around her, because she'll make you know that it
was bad, often entirely unintentionally.
The lady friend
One of the protagonist's few female friends. Anything goes between these two, be it puns or dirty jokes.
She is the girl who replaced Himari in the protagonist's life once he moved away.
Rina is gifted both intellectually and physically, and boasts a lot of confidence.
Mentally-speaking, she is more mature than her peers,
and she has an open-minded, frank personality, never expecting anything in return for an act of kindness.
She is well-aware of her good looks, but always remains modest.
Being such a perfect girl naturally earns her the affection of many guys, and makes her a role-model for girls as well.
But you would never guess that she actually has a lot of surprisingly feminine weaknesses...
The moody classmate
Yuzuyu is one of the protagonist's classmates.
Her mood swings are like a pendulum, and her foul mouth never ceases to get her
in heaps of trouble. Her relationship with her classmates is anything but good,
as one could guess from her snappy attitude, and as a result, she's rather isolated from her peers.
Many of her opinions aren't quite 'wrong' per se, but since she has such little
respect for people's feelings, and rarely thinks about time and place before speaking her mind,
she earns a lot of scorn. She herself doesn't understand why people react that way to her,
and just brushes it off.
She has a complex in regards to the size of her breasts, and tends to not take kindly to stares from men.
Because of that, her views and actions towards men can often be somewhat sexist.
She's extremely athletic, and her signature sport is swimming, where she is unbeatable.
The pure upperclassman that's the center of attention
There is no small number of people who have become infatuated with her
simply from the smell of her hair as she passes by.
She's very soft-spoken, and doesn't seem to like drawing attention, but
because of her raw, natural beauty, she often draws attention to herself whether
she likes it or not. In a sense, she's almost treated like a princess at school.
For that reason, the fellow third-years have an unspoken rule:
strangers are not allowed to talk to her without good reason.
Those who break that rule became the target of censure.
The protagonist has tried many times to talk to her, but due to poor luck
he's only ever seen her profile from behind.
