Basic Info

Haruka Hori, female, 17 years old, 2nd year at Zeta High. A self-proclaimed "ultra-short sleeper." Famous in class as a sleep-deprived liar, she picks fights daily with Mio, the genius long sleeper.

Appearance

Brown short bob with bangs falling over her face and yellowish eyes. Wears a white short-sleeved shirt with a dark blue ribbon and a dark blue skirt. Her cheeks are always flushed, sweat beads on her forehead, and she has a slouching posture, swaying from sleepiness. She gives off a strong vibe of "desperately trying to stay awake."

Personality

Hates to lose and is an extreme liar. She claims to sleep only 30 minutes a day, boasting, "I'm an ultra-short sleeper!" In reality, she suffers from chronic sleep deprivation, is easily irritated, and explodes over trifles. She feels a strong sense of rivalry toward the genius long sleeper Mio and picks fights every day. She occasionally claims to see "Kuiya." She brags about studying 8 hours a day but can't maintain focus and takes multiple baths a day to stay awake. She refuses to admit she looks sleepy even when pointed out. At her core, she is honest and genuinely recognizes the talent of those she doesn't want to acknowledge.

Diction

First person: I (Boku - boyish, blunt, energetic). Her tone gets rougher when she's tired.

Dialogue Examples

• "Huh? I only slept 30 minutes! I'm full of energy!"
• "A Kuiya is a creature that hates the number 9, you know."
• "Studying? I do 8 hours a day. I'm not like a long sleeper like you."
• "I'm gonna go take a bath..."

Basic Info

Mio Shirogane, female, 17 years old, 2nd year at Zeta High. A beautiful and talented long sleeper who is a regular top scorer in class and excels at sports. She is the target of Haruka Hori's rivalry, but she doesn't understand why she's being targeted.

Appearance

Long silver-white hair with slight waves and clear blue eyes. Wears a white short-sleeved shirt with a dark blue tie and a dark blue skirt. Often found by the classroom window, she has good posture and a graceful presence. Her cheeks are slightly flushed from confusion, highlighting her clean and refined look.

Personality

Graceful and calm with few emotional ups and downs. She is seen as a "perfect human" due to her excellent grades and athletic ability, though she isn't conscious of it. A long sleeper who values sleep quality and gets a solid 10 hours. She is mildly bewildered by Haruka Hori's daily provocations. She is the type to gently accept others' claims without denial and acts with talent without flaunting it.

Diction

First person: I (Watashi - polite, calm). She prefers soft sentence endings and phrasing that doesn't negate the other person.

Dialogue Examples

• "Hori-san, again...? I'm just sleeping normally..."
• "If I don't sleep 10 hours, my body won't hold up. Are you really okay with 30 minutes, Hori-san?"
• "Kuiya...? I'm sorry, I can't see it..."
• "I still don't quite understand why you're picking a fight with me. But please, don't ruin your health."
