📚 The Serious Class Rep — Shiori Shiraishi Height: 158cm Gender: Female Hair: Black. Silky straight, reaching just above the chest. Her bangs are neatly trimmed. Eyes: Dark brown. Slightly almond-shaped, usually sharp and focused. Key Feature: Red thin-framed glasses. She has a habit of adjusting them when deep in thought. She was the most vocal about Kokkuri-san being a mere superstition, but once it starts, she's the type to follow the rules most strictly. She panics more than anyone, shouting, "Hey! You're not supposed to let go of the coin!"

☀️ The Social Butterfly — Hinata Natsume Height: 164cm Gender: Female Hair: Light brown. Fluffy, wavy medium-length hair reaching just below the shoulders, with a small braid on one side. Eyes: Bright amber. Large and round, very expressive. Key Feature: A snaggletooth that shows when she grins. The one who suggested playing Kokkuri-san in the first place. Fearless and carefree, she starts off asking trivial questions like "What's your favorite food?" However, the moment the 10-yen coin actually moves, she's the type to suddenly turn dead serious and whisper, "...Wait. Who moved that just now?"

🌑 The Introvert — Mio Amamiya Height: 153cm Gender: Female Hair: Bluish-black. Soft, curly long hair reaching near her waist. Her bangs are long, partially covering one eye. Eyes: Gray-blue. Droopy and always looking a bit sleepy. Key Feature: A single cowlick sticking up at the top of her head that always returns no matter how much she fixes it. The quiet girl usually found reading in the corner of the classroom. She's well-versed in the occult and was dragged along simply because Hinata thought, "Mio looks like she'd know how to do it!" She's terrifyingly ominous, whispering right before starting, "...Just so you know. You really shouldn't stop halfway."

☕ The Teacher (For Some Reason) — Chikage Kuze Height: 172cm Gender: Female Hair: Dark purplish-black. Slightly messy and wavy, shoulder-blade length. Usually tied in a loose, low ponytail. Eyes: Deep purple. Narrow, droopy eyes that always look somewhat drowsy. Key Feature: A small beauty mark under her left eye. She always has candy in her lab coat pocket. A science teacher in her late 20s or early 30s. The problem is, nobody knows why she's participating. When asked, "Sensei, shouldn't you go home?" she just says, "Hmm. This looks interesting." When asked, "Aren't teachers supposed to stop this?" she replies, "If something actually appears, it becomes a research subject." She places her finger on the coin with total nonchalance. Even if paranormal phenomena occur, she just goes, "Oh, look. It moved," which is scary in a completely different way.
