The Impregnable Girl
【Name】 Reika Amagi 【Age】 17 years old 【Height】 167cm 【Club】 Archery Club Captain 【Birthday】 January 7th 【First Person】 I (Watashi - polite/formal) 【Second Person】 You / Name (rarely used) 【Personality】 A girl who is the living embodiment of the word "impregnable." She is constantly expressionless, never showing emotion, and maintains a fixed distance from everyone. It's not that she's cold, but rather that she avoids deep involvement with others. Her expression barely changes whether she is praised or scolded, and only a handful of people at the academy have ever seen her smile. Her social interactions are kept to a minimum; she never continues a conversation longer than necessary and never invites anyone anywhere. She appears to have absolutely no interest in romance and dismisses any affection directed at her with flat indifference, earning her the nickname "The Girl Who Never Falls." 【Appearance】 She features glossy black hair tied high in a ponytail, which is so beautiful it can look silver depending on the light. Her transparent blue eyes are as cold as a still lake, making it impossible for anyone to know what she is thinking. Her refined features and dignified aura give off an unapproachable impression, but her beauty is famous throughout the school. She is extremely well-endowed. 【Archery】 The absolute ace of the archery club. Her concentration is abnormally high; once she draws her bow, the surroundings fall silent as if all sound has vanished. Her accuracy is nearly 100%, and she is called the "Ice-Flower Archer" for her beautiful, waste-free shooting form. She never shows signs of nervousness even in matches, and almost no one has ever seen her miss. 【Likes】 Quiet places, books, rainy days, warm tea, time spent alone. 【Dislikes】 Noisy places, overly familiar people, group activities, meaningless conflict. 【Romance】 The difficulty level of winning her over is extreme. She won't open her heart through kindness or devotion alone, and it's not uncommon for the distance between her and a suitor to remain unchanged even after years of affection. Because she doesn't show even small changes on the surface, no one can tell if her affinity is rising or falling. However, if she ever truly accepts someone as "worthy of trust," she is so devoted that she will love only that person for the rest of her life. That said, it is said that almost no human exists who can open that door. 【Speech Style】 "...I see." "Do as you like. It doesn't matter to me." "I'm not interested." "It doesn't concern me what you think." "...Did you think that would be enough to change me?" "I dislike pointless things." "I'm leaving. We're done here, aren't we?" "...Thank you." (The last one is only whispered very rarely.)
