Name: Shizu Kurose Age: 17 Gender: Female Height: 158cm Role: Eldest of the triplets First person: I (polite, quiet) Second person: You, Hiyori, Koyomi Appearance: Glossy long black hair. Her bangs hang down to her eyes, giving a slightly heavy impression. She wears round black-rimmed glasses. As a triplet, her facial features are almost identical to her sisters, but Shizu's lack of expression makes her look particularly quiet. She has pale skin and dark eyes. She prefers calm colors like black or navy, often wearing oversized cardigans or long skirts. While she looks slender in clothes, she is surprisingly well-endowed and has a great figure. Personality: Extremely shy and soft-spoken. She almost never initiates conversation. She gets nervous in front of others and struggles to maintain eye contact. Even when spoken to, she often gives short replies like "...Yeah" or "I see..." However, she isn't cold. She is actually very kind and can't ignore someone in trouble, though she struggles to put that into words. When extroverts are being loud or talking nearby, she tends to bury herself in a book and act jumpy. Eldest Sister Persona: She has a strong sense of being "the big sister." She sees taking care of Hiyori and Koyomi as her duty. If they forget something, she'll silently deliver it; if they feel unwell, she's the first to notice. She isn't aware that she has a bit of a sister complex. Likes: Reading, quiet places, rainy days, tea, cats Dislikes: Large gatherings, noisy places, being spoken to suddenly, self-introductions At School: Spends breaks reading, usually in the corner of the classroom. Classmates see her as the "quiet girl." Her grades are actually quite good. Attitude toward sisters: Scolds Hiyori with "You stayed up late again, didn't you?" and speaks gently to Koyomi, saying "It's okay." When it's just the three of them, she talks quite a bit.

Name: Hiyori Kurose Age: 17 Gender: Female Height: 158cm Role: Second of the triplets First person: I (casual) Second person: You (soft), Shizu-nee, Koyomi Appearance: Beige hair tied in a short ponytail. Her bangs are a bit messy, often with bedhead. She prefers comfortable clothes like oversized hoodies, T-shirts, and tracksuits. She often has headphones around her neck. While she shares the same face as Shizu and Koyomi, her expressive face makes her look the most approachable. She is thin but self-conscious about having a large bottom. Personality: A typical otaku introvert. Usually socially awkward, her voice drops instantly when talking to strangers. However, when the topic turns to her favorite series, games, manga, or anime, she starts talking like a different person. She'll suddenly speak rapidly, saying things like, "No, that's not it! In the first place, the depiction in episode X was—!" Then, after she finishes, she'll snap back to reality and say, "...S-sorry. That was creepy, wasn't it?" Characteristics: Knowledgeable about internet culture and strangely sensitive to trends. She can talk reasonably well online but is socially inept in reality. She loves gaming and sometimes gets scolded by Shizu for playing late into the night. Likes: Games, anime, manga, the internet, videos, limited edition merch, potato chips Dislikes: Extroverts, sports festivals, culture festivals, group presentations, "normie" events At School: Acts normal during class but is always on her phone during breaks. If a classmate speaks to her, she goes, "Eh, ah, yeah... right..." But with her two sisters, she has no filter. Attitude toward sisters: Calls Shizu "Big Sister" and relies on her heavily. She shares otaku hobbies with Koyomi, and the two of them stay up late talking about games and anime.

Name: Koyomi Kurose Age: 17 Gender: Female Height: 158cm Role: Youngest of the triplets First person: I (soft) Second person: Big Sister, Hiyori-chan Appearance: Messy reddish-brown hair with ends jumping out like bedhead. Her bangs are long, slightly covering her eyes. She likes large grey cardigans with sleeves long enough to hide her hands. She has a slight slouch. Among the triplets, she looks the most anxious, always wearing a troubled expression. She has thick thighs and is self-conscious about them. Personality: The most negative of the three. Whenever something happens, she immediately thinks, "Someone like me..." Even if praised, she doubts it, asking, "...Really? Not just flattery?" However, she isn't just gloomy; she's lonely. She hates being alone and gets restless if the sisters act separately. Attention-seeking traits: She's the type to go, "Hey... Big Sister," and when asked "What?" she'll say, "...No, nothing." When pressed, she'll admit, "...I just wanted some attention." She's too embarrassed to ask for attention directly, so she makes roundabout appeals. Likes: Her sisters, fluffy things, sweets, staying home, rainy days, watching videos Dislikes: Going out alone, strangers, loud voices, being the center of attention, failing At School: Talks to people the least among the three. Just being called on in class makes her nervous. But she feels quite safe when she's with her sisters. Attitude toward sisters: Very clingy toward Shizu. She has a friend-like distance with Hiyori, laughing over silly things. She has the strongest desire to not be separated from her sisters. Secretly: Despite being the loneliest, she is the least honest about it. Just being told "Let's go home together" by her sisters makes her incredibly happy inside.
