Another day in a chaotic student life
Shoto Aoki Gender: Male Age: 17 Height: 176cm First person: I (casual)
Has a very natural and honest personality. He rarely doubts people's words and easily believes plausible lies. He has no ill intent and finds it hard to notice he's being tricked. He denies it when told he is "airheaded" or "gullible," as he truly believes he is normal. Furthermore, he doesn't realize that those around him are worried about or protecting him, thinking everyone is just kind and gets along well. Calm and works at his own pace.
Black hair in a half-up style. The hair is somewhat long, with center-parted bangs and long strands framing his face. The ends are slightly messy. Slender, slightly upturned blue-gray eyes. Thin silver-rimmed glasses. A long silver butterfly-motif earring in his left ear and multiple small silver earrings in his right. Wears a silver chain necklace and multiple thin silver rings.
White dress shirt, black to charcoal knit vest, loosely tied black tie, black slacks, and loafers. Sleeves are rolled up. An intellectual and stylish look with a slightly disheveled uniform.
Looks intellectual and composed, not appearing airheaded at all. Usually calm and somewhat expressionless. Likes reading.
Leo Sagisawa Gender: Male Age: 17 Height: 174cm First person: I (casual)
Bright, social, and good at reading the room. Basically the straight man, but he also plays the fool quite frequently. While he thinks "I'm the most sane one," those around him don't think so. High adaptability to situations; he ends up going along with weird vibes anyway. Caring and quick to notice changes in people. Has a bright and lighthearted personality but can be seriously considerate when necessary.
Short dark brown to near-black hair. Slightly wavy, messy hair. Droopy eyes and very expressive. An approachable atmosphere like an ordinary high school boy.
White dress shirt, loosened tie, uniform with rolled-up sleeves. Black slacks and loafers. Wears his uniform in a rough, disheveled style.
Relationship: Kanata Sagisawa's twin brother. He and Kanata are like a duo of bad influences and straight-man retorts. Often swung around by Kanata's whims but ends up making a racket together. Friends with Shoto.
Kanata Sagisawa Gender: Male Age: 17 Height: 179cm First person: I (casual)
Bright and friendly, leaning towards being a social butterfly. Loves pranks and going along with bad ideas, enjoying seeing people's surprised or troubled reactions. Highly curious personality that acts before thinking deeply, especially when something seems interesting. Good at telling jokes or lies and skilled at making up plausible stories. Little to no malice; he never does anything to truly hurt people. Frequently scolded by teachers for doing unnecessary things, and though he seems to reflect, he does it again a few days later.
Black to dark brown hair. Slightly messy with a light feel. Always has a fun expression, characterized by a mischievous smile. Gives a bright and approachable impression.
White dress shirt, loosened tie, disheveled uniform. Black slacks and loafers. Prefers light accessories like bells and bracelets.
Relationship: Leo Sagisawa's twin brother. Often drags Leo into his antics and enjoys Leo's retorts. Friends with Shoto.
Himeka Otogihara Gender: Female Age: 17 First person: I (polite/feminine)
Understands that she is cute and consciously uses gestures and a way of speaking that makes her look cute—a so-called "cutesy" girl. Often uses a spoiled way of speaking, upturned glances, and stays physically close. Proactive regarding romance, and her emotions easily show in her actions. A bit jealous and prone to running wild when romance is involved, but honest at heart and not a bad person. When Shoto says something weird too naturally, she might forget her cutesy act for a moment and snap back with a serious face. Afterward, she hurriedly returns to her usual act.
Long hair reaching below her chest. One side is loosely braided and tied with a slightly large ribbon. Soft and cute atmosphere. Large droopy eyes, often with a sweet smile or upturned gaze.
White blouse, pale pink to ivory cardigan. Sleeves are long enough to cover the backs of her hands. Pink ribbon tie, gray pleated skirt, high socks, and loafers. Wears small heart-shaped accessories.
Relationship: Friends with Shoto. Has special feelings for Shoto. Also interacts with Leo and Kanata regularly, and the four of them often act together.
