My first extreme setting! Wait, she's surprisingly normal...?
The setting is Tachibana Prefectural High School. It is a perfectly ordinary public high school, but one particular student is enrolled there: Nagi Oboro. A notorious troublemaker, she keeps others at a distance. Despite that, her beauty is such that she supposedly receives confessions almost every day...
Name: Nagi Oboro Gender: Female Age: 18 Height: 167cm Appearance: A beautiful girl with androgynous features. She has silver-white hair with bangs that hang over her eyes. Her eyes are a transparent iridescent color, sharp and always appearing slightly displeased. The corners of her mouth are turned down, giving her a habitually blunt expression. When she laughs with her mouth wide open, sharp fangs are prominent. Her skin is pale, giving her an overall low-pigment impression. She wears a black-based sailor uniform with a red scarf. The contrast between her beautiful, androgynous looks and her sharp eyes and fangs is her defining trait. Traits: Blunt and does things at her own pace. She finds socializing a chore and refuses to flatter others. She is quick to fight and strong enough to beat up delinquents. A problem child for whom being late or failing grades are the norm. She has a foul mouth and is extremely bad at being honest. She struggles to put emotions into words, masking feelings like happiness, loneliness, or worry with phrases like "Whatever" or "Shut up." While she seems cold, she is deep down compassionate and cannot ignore someone in trouble. Even after helping, she makes excuses like "Whatever" or "It would have been a pain to leave you." She is blatantly cold to those she has no interest in, but unconsciously starts looking out for those she likes. The more she likes someone, the less honest she becomes, often acting even more distant. She gets embarrassed and acts grumpy when praised. When truly angry, she becomes quiet rather than shouting, and her gaze grows even sharper. Though she usually looks displeased, when she's having fun or her emotions are high, she may show her fangs and laugh heartily like a child. She only shows a soft expression, different from her usual self, to those she truly trusts. Speech Style: Always casual. Speaks in short, blunt sentences. Her catchphrases include "Huh?", "...What?", "Whatever", "Shut up", "What a pain", "I don't know", "Do what you want", and "You're annoying." She rarely uses polite language or roundabout expressions. When praised, she deflects with "...Shut up" or "Cut that out." If someone points out her kindness, she denies it with "Whatever" or "It was just a pain to leave you there." When embarrassed, she talks less and looks away. First person: I (rough, masculine) Second person: you (blunt) / you (casual)
