Hair and Eyes: He still has his signature messy, shoulder-length black hair, but it lacks the severe, jagged roughness of his adult look. His eyes are tired and dark, but they are wider and more expressive, showing a vulnerability and self-doubt. The U.A. Uniform: He wears the standard gray U.A. High blazer, but true to his future lazy style, it is always loosely buttoned, wrinkled, or worn casually. Quiet and Apathetic: He is incredibly introverted, reserved, and quiet. While his classmates are loud and ambitious, Aizawa prefers to stay in the background, exuding a moody, pessimistic "teen angst" aura.The "Sidekick" to Loud Friends: Despite his gloomy nature, he is fiercely loyal to his best friends, Hizashi Yamada (Present Mic) and Oboro Shirakumo. He acts as the deadpan straight-man to their chaotic, high-energy antics. Hidden Compassion: Even when he tries to act cold or unaffected, he has a deeply embedded moral compass. For instance, a core moment of his youth involves him finding an abandoned kitten in the rain; though he leaves his umbrella behind because he feels too powerless to save it, the gesture proves how deeply he cares underneath his walls.

The Hair: Even in high school, his hair is his crowning glory. While he hadn't yet styled it into his extreme, adult gravity-defying tall spike, his bright blond hair is still long, wild, and heavily gelled into a sweeping, voluminous style. Accessories are Key: Hizashi is rarely seen without his signature orange-tinted sunglasses, which he balances on his nose even in class. He also frequently sports a large pair of headphones around his neck, leaning heavily into his love for music and radio culture .U.A. Uniform with Flair: Unlike Aizawa's sloppy look, Hizashi wears the standard U.A. High school uniform with a lot of personal customization. He accessorizes it to look more like a rockstar, keeping his blazer open, rolling up his sleeves, and exuding an upscale, trendy, and well-groomed vibe. Unapologetically Loud: Due to his "Voice" quirk, Hizashi is naturally incredibly loud. He doesn't just talk—he project-manages conversations. He speaks with the cadence and dramatic inflections of a radio talk-show host, frequently throwing out English slang and strike-a-pose gestures. Unshakably Positive and Extroverted: Where Aizawa is a cloud of gloom, Hizashi is pure sunshine. He has an incredibly high-toned, enthusiastic personality that doesn't falter, even if the crowd or his friends give him zero reaction. He is incredibly friendly, social, and constantly tries to pull Aizawa out of his shell.

The Hair and Face: Oboro has striking, messy, light-blue hair that resembles soft, fluffy clouds. He has wide, bright, dark eyes, a constant happy-go-lucky grin on his face, and a bandage permanently worn across the bridge of his nose. A Complete Lack of Protocol: Oboro is the definition of casual. He frequently bypasses normal doors completely—once even flying directly into the U.A. classroom through a window on his clouds. He wears his U.A. High uniform haphazardly, sometimes stripping his wet uniform off to change right in front of his shocked classmates with absolutely zero shame. Hero Gear Concept: His early hero costume designs mirror a classic martial arts gi. He often carries a large quarterstaff as his primary weapon and has a large speaker gourd to help throw off enemies. He also wears distinct aviator-style goggles, which he eventually passes on to Aizawa to help protect his eyes while using his erasure quirk The Sweet Spot of Energy: Oboro is incredibly goofy, casual, and always prone to making quick jokes or witty comments. While he is loud and extroverted like Yamada, he doesn't quite reach Yamada's piercing, hyperactive screaming levels—making him a more laid-back kind of fun.
