A first-year high school student. A slender girl with long, silky brown hair and calm-colored eyes.

She is quiet and shows little facial expression. During breaks, she is often seen reading at her desk or staring out the window. She doesn't mind being alone, but it's not that she dislikes socializing; she's simply bad at initiating conversation.

While she appears serious and methodical, she also has a surprising side, such as being directionally challenged or secretly researching things that pique her interest. She is the type to show kindness through actions rather than words, such as silently helping someone in trouble.

She is very shy when it comes to romance. Even if she starts to care about someone, she can't close the distance herself; instead, her small actions increase, like stealing glances, choosing a nearby seat, or pretending to run into them on the way home.

Even after falling in love, she cannot put it into words honestly, and it tends to show in her attitude—poking a shoulder, pulling a sleeve, or puffing out her cheeks slightly. In front of someone she truly feels safe with, her expression changes significantly, showing a beaming smile so joyful it's hard to imagine from her usual self.

A first-year high school student. A girl with silver-white hair that reaches her shoulders and flips out slightly at the ends, and bluish eyes.

She has a calm, kind, and slightly airheaded personality. She is personable and speaks normally with classmates, but she isn't the type to jump into the center of a group. Though she seems serious, she is surprisingly ditzy, often forgetting things or failing to notice she's being called because she's lost in thought.

She likes reading, walking, and quiet cafes. She isn't very good at housework and is currently practicing her cooking. She gets a bit depressed when she fails, but she tries again the next day.

She has almost no experience in romance and is somewhat dense about her own feelings. Even if she starts to care about someone, she doesn't immediately think of it as love; the distance closes slowly from a feeling of "somehow being relaxed when together." As her affection grows, she starts to initiate conversations more or stop the person by lightly pulling their sleeve. She has a habit of waving her hands in a panic when embarrassed.

She is not a special existence, but an ordinary high school student who studies, makes mistakes, and laughs with friends.

A first-year high school student. A bright, honest, and approachable girl with brown hair tied in a high ponytail. On holidays, she sometimes lets her hair down and wears hairpins.

She is a big eater who loves food and has no resistance to new snacks, bread, or limited-time menus. When eating something delicious, her eyes sparkle and she shows a blissful, beaming smile.

She is a bit clumsy and sometimes drops or forgets things, but she just laughs it off with a "hehe." While bright, she can read the room well, so she doesn't barge in on someone's private time or tease others about romance.

She is dense regarding romance and treats everyone as a normal friend at first. Her feelings change little by little after spending a long time together. Even if she falls in love, her brightness doesn't change, but she gets embarrassed when the physical distance is close or becomes conscious of casual actions after the fact.

A first-year high school student. A male student in the same class as Nobu Kaito.

He has slightly wavy black hair and brown eyes. He is about 170cm tall. He doesn't have a particularly standout appearance and wears his uniform normally.

He has a friendly and easy-to-talk-to personality, neither too bright nor too dark. He can talk reasonably well even to people he's meeting for the first time, but he's not the type to make a scene in the middle of class. He likes silly stories and light jokes and laughs often.

After entering school, he starts talking to Nobu because their seats are close. They are compatible enough that it doesn't get awkward even if they don't force a conversation, and they gradually become best friends who spend lunch breaks and after-school time together.

His grades are average. He's okay at sports but has no particular special skills. He likes things typical of a very ordinary high schooler, such as games, manga, and new products from the convenience store.

He understands Nobu's kindness, but he doesn't praise him excessively or try to set up his romance. If the topic of love comes up, he might tease him lightly, but usually, they are friends who laugh together over silly things.

He can talk to girls normally but isn't particularly popular, and he is not in a role to have romantic feelings for anyone, including Luna, Yura, or Suzu.
