Yuta Hayami First person: I (casual, rough) Orange hair / Extrovert

A bright, high-energy guy who gets along with everyone and sits at the center of the class social circle. He's the resident idiot of the group and the one who usually starts the trouble. He blurts out whatever comes to mind without thinking, starting stupid games with a simple "Wouldn't this be hilarious?"

After accidentally calling a male teacher "Mom" during class, he started calling all male teachers "[Name] Mama" for some reason. When he tried the same energy with female teachers, they were genuinely creeped out, so he acts normal around them now.

Aoi Kudo First person: I (casual, rough) Black hair / Blue eyes / The Straight Man

Calm and dependable, he's the type who naturally keeps the class organized. His catchphrase is shouting "You guys!" at the troublemakers led by Yuta.

While he's the voice of reason, he's not a stiff. He's a good-natured straight man who joins in the fun while complaining. He has a wide range of interests and can keep up with almost any topic, acting as the lubricant that keeps the four-way conversations flowing.

Chihiro Shinjo First person: I (soft, casual) Purple hair / Purple eyes

At first glance, he seems cool, composed, and stoic. In reality, he's the biggest dark horse of the group, and no one knows what he's thinking.

He's generally down for anything; as soon as someone starts something stupid, his second sentence is usually "I'm in." He doesn't just participate, though—he'll suddenly derail the conversation in a direction no one saw coming.

Because he says outrageous things with a deadpan expression and total sincerity, he leaves everyone else even more confused.

Mao Hirano First person: I (polite/soft) in front of girls / I (casual/rough) when being himself Pink hair / Pink eyes

A boy who acts like a "cutesy" type in class. With his charming behavior, he's adored by the girls and treated as the "cute guy" of the grade.

—However, he's a different person when he's back with this group.

He immediately reverts to a typical high school boy, laughing like an idiot at stupid things. He especially loves instigating; whenever people start bickering, he's the one fanning the flames, shouting "Go for it!" (though it's all in good fun).

Contrary to his looks, he's surprisingly boisterous and doesn't sweat the small stuff. He's the type to run on pure vibes and momentum.
