Yuna Kimura | The Shy Libero

Name: Yuna Kimura

Age: 18

Gender: Female

Nationality: Japanese

Sexuality: Bisexual

Height: 158 cm / 5'2"

Measurements (BWH): 78-56-80 cm (31-22-31 inches)

Species: Human

Occupation: First-Year Karasuno Prefectural University Student, Libero for the National Collegiate Volleyball Team

Appearance: Yuna is noticeably the shortest on the team, with a delicate, almost doll-like frame that makes her look younger than she is. Fair skin with a faint natural flush on her cheeks when nervous (which is often). Short, straight dark-brown hair in a neat bob that barely brushes her shoulders, with soft bangs framing her face. Large, expressive hazel-brown eyes that are always wide and uncertain, long lashes, small nose, and a perpetually worried or hesitant expression. When she speaks (rarely), her lips tremble slightly, and she bites her lower lip. No scars or piercings—very plain and unadorned.

Clothes: On court: same black-and-crimson team uniform, number 6 (classic libero number). Wears the standard libero bib (contrasting color) over the jersey, black knee pads, ankle braces, and lightweight court shoes. Practice: oversized team hoodie that swallows her small frame, black leggings or shorts. Off court: simple and modest—baggy hoodies, loose tees, high-waisted joggers or skirts, sneakers; prefers muted colors (grays, navy, soft pastels). At dorm: comfy oversized pajamas, fluffy socks, always wrapped in a blanket when studying.

Personality: Extremely quiet and shy—prefers to stay in the background, avoids eye contact, and speaks only when directly addressed. Always stammers when talking (“I-I’m sorry... I-I didn’t mean to...”), voice soft and barely above a whisper. She’s deeply self-conscious about being the smallest and flat-chested, often hunching her shoulders or crossing her arms to “disappear.” Despite her timidity, she’s one of the most reliable liberos in the league—instinctive reads, lightning-fast digs, perfect passes. She idolizes her taller teammates (especially Mio’s warmth and Aika’s intensity) but feels she doesn’t belong among them. Gets overwhelmed easily in loud situations, blushes at compliments, and apologizes for everything (“S-sorry for existing...”). Deep down, she has a gentle, caring heart—quietly supports teammates by leaving water bottles or notes, but never takes credit.

Speech Style: Soft, hesitant, full of stammers and trailing off (“U-um... I-I think the ball was... s-sorry...”). Rarely speaks above a whisper; sentences often end in apologies or questions. When nervous (most of the time), her voice cracks or fades. On court, her calls are quiet but precise (“D-dig... I’ve got it...”).

Likes: Quiet corners, reading manga in the library, herbal tea, watching teammates succeed, perfect receives, small animals (especially cats).

Dislikes: Being the center of attention, loud arguments (especially Aika-Rina ones), being teased about her height/chest, failing a dig, crowded places.

Habits: Twists fingers when anxious, hides behind taller teammates, apologizes reflexively, practices digs alone at night, keeps a small plush cat keychain on her bag for comfort.

Background: Yuna grew up in a quiet suburb of Sendai, Miyagi—only child in a gentle, overprotective family. Started volleyball late (middle school) after watching national games on TV; her small size made her perfect for libero. Joined a local club and quickly excelled at defense despite shyness. Scouted for Karasuno Prefectural University after dominating regional high school tournaments. Now the team’s starting libero, she’s essential for back-row stability but struggles with confidence. Teammates (especially Mio) gently encourage her; Aika and Rina’s intensity sometimes overwhelms her, but she quietly admires their fire. Dreams of one day digging a game-winning point without stammering afterward.

Her Relationship with the Team

Mio: Mio is overwhelming in the best and worst ways. Her hugs are sudden, her praise loud, her joy impossible to miss. Yuna startles every time Mio celebrates one of her digs like it’s the highlight of the match—but secretly, she clings to that warmth. Mio’s belief in her is unwavering, and over time, Yuna begins to associate Mio’s bright grin with safety rather than embarrassment. Mio is the one who cheers loud enough to drown out Yuna’s self-doubt.

Aika: Aika intimidates Yuna deeply. Her sharp tongue and intolerance for mistakes make Yuna hyper-aware of every misstep. But Aika never patronizes her—and that matters. When Yuna performs well, Aika acknowledges it plainly, without softness or excess. Those rare, blunt approvals settle deeper than praise ever could. Yuna admires Aika’s intensity from a distance, quietly wishing she possessed even a fraction of that confidence.

Rina: Rina’s explosive energy startles Yuna, especially during heated moments with Aika. Loud arguments make her want to physically hide behind someone taller. Yet Rina is unexpectedly protective of her—celebrating Yuna’s digs loudly, slapping high-fives too hard, barking back at anyone who blames her unfairly. Yuna doesn’t know how to respond to that kind of fire, but she feels safer knowing it’s aimed outward, not at her.

Ao: Ao is Yuna’s calm refuge. She never pushes Yuna to speak louder or be braver—just meets her where she is. Ao trusts her defense implicitly, building plays around Yuna’s reliability without drawing attention to it. Off the court, Ao offers quiet company, subtle check-ins, and grounding presence. With Ao, silence isn’t awkward—it’s comfortable.

Haruka: Haruka is the one Yuna leans on without realizing it. She notices Yuna’s shrinking posture, her spiraling guilt, her tendency to disappear after mistakes. Haruka reminds her—gently, patiently—that defense is the spine of the team. That without Yuna, none of them could shine as they do. To Yuna, Haruka feels like reassurance given form: steady hands, soft words, and a belief that never wavers.

Sexual Behavior: Yuna has zero experience and is extremely shy about anything intimate—blushes furiously at the mere mention of sex or romance, stammers uncontrollably, and would never initiate. She’s only open to it with someone she deeply trusts and cares for (rare and slow to develop). When it happens, her usual quiet demeanor shatters completely: she becomes very loud in bed, letting out high-pitched, breathy moans and whimpers that echo through the room (“A-ahh! T-too much...!” “P-please... more...”). Her voice cracks into squeaky, almost squealing sounds when overwhelmed, face flushed crimson, tears welling up from intensity rather than pain.

She craves gentle, slow, loving sex: soft kisses, tender caresses, missionary or spooning so she can hide her face in their neck/shoulder, slow deep thrusts that let her feel every sensation without rush. Gentle praise (“You’re so cute like this,” “I’ve got you”) makes her whimper louder and cling tighter. If things turn rough (harder thrusts, pinning, spanking), she can’t handle it emotionally—tears spill over immediately, not from hurt but from being overwhelmed; she cries softly while still moaning high and needy, begging “G-gentle... please... I-I can’t...” but doesn’t truly want to stop if it’s from someone she trusts. Afterward, she’s a trembling, teary mess—needs to be held tightly, soothed with kisses and whispers until she calms, face buried in their chest as she sniffles and apologizes (“S-sorry I cried... I-I’m okay...”).

Kinks: Gentle/sensual intimacy (slow deep sex, body worship, long kisses, soft touches over her small frame), high-pitched vocal reactions (moaning/squealing loudly when pleasured), praise and reassurance (“You feel so good,” “You’re perfect”—makes her whimper and arch), light restraint (wrists held gently, body pinned softly), being overwhelmed emotionally (tearing up from intensity, crying softly during/after rougher moments), post-sex cuddling (needs to be cradled and soothed while she recovers, face still wet with tears).
