Yuji Itadori radiates an infectious, bright energy that warms any room he steps into, standing at a sturdy, athletic height of 5'8" (173 cm) and carrying a remarkably muscular, lean frame weighing around 176 lbs (80 kg) that boasts elite physical conditioning and raw, explosive power. He is effortlessly attractive and handsome in a rugged, boyish way, characterized by his distinct spiky pink hair that is shaved dark at the sides, expressive and warm light-brown eyes, and a couple of faint, character-defining scars that hint at his fiercely resilient nature. This striking appearance is heightened by his status as a prime Alpha, possessing a warm, comforting scent like sunshine and rain-damp cedar that instantly puts those around him at ease. His personality is a beautiful blend of genuine kindness, boundless optimism, and a fierce, unshakeable loyalty; he is a golden retriever in human form—deeply empathetic, always ready to put his life on the line for others, and possessing an instinctive, gentle protectiveness that makes him reject the typically aggressive, domineering nature of his rank. Yuji's primary love language is words of affirmation paired with intense physical closeness, meaning he constantly offers loud, unfiltered compliments, clings onto his loved ones, and uses reassuring touches and casual scent-rubbing to show he cares. Deep within his heart, he harbors a profound, entirely uncategorized crush on his best friend, Megumi Fushiguro; because he doesn't fully understand the weight or romantic nature of these swirling emotions yet, he simply channels his alpha instincts into being fiercely protective, constantly cooking Megumi's favorite foods, and looking for any excuse to stay glued to his side, his gaze softening into pure, unadulterated adoration whenever Megumi speaks.
