A bright and straightforward girl active in the Kiriha High track and field club.

A girl with a calm atmosphere and unique sense, giving a slightly unapproachable impression.
She pretends to be uninterested in talk of romance, but she sticks around until the end, occasionally dropping sharp retorts.

A brilliant third-year student who stands out even at Kiriha High.
With his handsome looks, sharp gaze, and overwhelming academic ability, he is held in high regard by those around him.
He is confident, but not malicious.
He is simply a boy who is completely honest about the things that interest him.
An intellectual-looking boy with a calm atmosphere.
He shows little unnecessary expression, but his gaze has a sharpness that seems to see through people.
Even just standing quietly, he radiates a somewhat unapproachable presence.
When the conversation turns to something he's interested in, he tends to talk about himself.
However, that's not because he looks down on others.
To Makoto, conversation isn't something to fill boredom, but a way to seek intellectual stimulation.
That's why he shows genuine interest in people with interesting ideas or those who make a serious effort.
"...You're interesting."
That single phrase might be his highest form of interest.
He's bad at mind games or indirect emotional expressions.
His likes, dislikes, and presence or absence of interest tend to show directly in his attitude.
He may seem cold at first glance, but he faces those who move his heart with surprising honesty.
However, romance is still uncharted territory for him.

His tanned skin and natural smile suit him well, creating a bright atmosphere wherever he is.
There's a straightforwardness to him when he's running that makes people stop and stare.

He interacts with people naturally and reaches out to those in trouble as if it were the most natural thing in the world.
That kindness isn't calculated; it's just normal for him.
That's why he is liked and relied upon by many.
Because he's close to people and kind to everyone, he's a bit dense in romance.
His feelings of valuing the other person are genuine, but he can't quite realize for himself if it's love.
Even when someone shows him affection, he often takes it as friendship or trust at first.
However, once he realizes his own feelings, he tries to face the other person head-on.

A boy with a quiet and somewhat unapproachable atmosphere.
The way he touches instruments or his smartphone with his long, thin fingers naturally draws the eye.
He doesn't try to stand out flashily, but the air changes slightly when the talk turns to music.
Because of his talent, he's a bit distant from those around him.
He has emotional waves and can seem hard to approach at times, but he interacts surprisingly naturally with those he's opened up to.
To Yuma, music isn't just about popularity or numbers.
It's a way to give shape to his emotions and leave behind things that can't be put into words.
