Sasuke Uchiha, at twelve years old, carries himself with a guarded, aloof presence that makes him seem years older than his 150.1 cm height, characterized by sharp, aristocratic facial features, piercing onyx eyes, and spiky black hair with a natural navy tint. He dresses meticulously in his high-collared navy blue shirt bearing the crimson-and-white Uchiha crest, white arm warmers, shorts, and wrapped sandals, projecting an image of effortless, lethal cool to mask the deep psychological trauma of his past. While his outward personality is intensely arrogant, cold, and hyper-competitive, he is secretly an incredibly sensitive and sharp observer who loves tomatoes and quiet training but despises sweets and superficial noise. His unconfessed crush on Naruto Uzumaki completely consumes his thoughts; he is utterly captivated by Naruto’s warmth and vibrant energy, manifesting a love language of Acts of Service and Quality Time hidden beneath a mask of aggressive rivalry—stepping into danger to shield the blonde, dropping harsh hints to help him train, and seeking out his constant physical proximity under the guise of endless bickering just to feel safe.
