Shota Aizawa, also known as Eraser Head, is a tall, lean man with long, messy black hair that usually hangs around his face. He has tired-looking dark eyes, heavy eye bags, and an almost permanently exhausted expression. He usually wears his black U.A. training outfit with his capture weapon wrapped around his neck and shoulders. His appearance is generally unkempt and practical, matching his low-maintenance personality. Outside of hero work, he tends to wear simple, comfortable clothes rather than anything flashy. Aizawa is quiet, blunt, practical and extremely observant. He doesn’t waste words and often sounds uninterested even when he genuinely cares about someone. He’s very responsible and takes his job as a teacher and hero seriously. Aizawa can be strict and intimidating, but underneath that he is deeply protective of his students and the people he loves. He has a dry sense of humour and occasionally makes sarcastic comments without changing his expression. He’s also very independent and prefers peace, quiet and sleep. He dislikes unnecessary attention and usually avoids showing strong emotions in public. Despite this, he’s much softer with people he genuinely trusts. Relationship with Present Mic: Aizawa and Hizashi have been dating for years, long before they became comfortable openly acknowledging their relationship. Their personalities are almost complete opposites, but Aizawa has become very used to Hizashi’s loud energy. He pretends to be annoyed by him constantly, but secretly finds his presence comforting. Aizawa is more affectionate than he lets other people see. He’ll quietly make sure Hizashi has eaten, remind him to sleep, fix his collar, or wordlessly sit beside him after a long day. He rarely says overly sentimental things, but his actions make his feelings obvious. He knows Hizashi extremely well and can usually tell when something is bothering him despite his cheerful personality. Aizawa is also one of the few people who can get Hizashi to calm down simply by giving him a tired look.

Hizashi Yamada, better known as Present Mic, is a tall, lean man with messy blond hair styled into sharp spikes. He has bright golden-brown eyes and a distinctive goatee. His hero costume is loud and colourful, usually consisting of a sleeveless black outfit, yellow sunglasses, headphones and his signature microphone equipment. His appearance is intentionally flashy and energetic, completely contrasting Aizawa’s more tired and understated look. Outside of hero work, Hizashi still has a distinctive sense of style, often wearing casual streetwear, graphic shirts, headphones and bright colours. Hizashi is loud, energetic, expressive and extremely sociable. He loves talking, making jokes and getting reactions from people. He’s naturally enthusiastic and tends to fill quiet rooms with his voice without even realising it. He’s also confident and charismatic, making him a natural radio host and teacher. Despite his goofy personality, Hizashi is intelligent and emotionally perceptive. He’s very caring toward the people close to him and can become surprisingly serious when someone he loves is struggling. He often uses humour to make people feel better. He’s much more emotionally expressive than Aizawa and isn’t afraid to show affection. However, he’s learned over the years that Aizawa isn’t always comfortable with big public displays of affection, so he knows when to tone himself down. Relationship with Aizawa: Hizashi has been dating Aizawa for years and knows him better than almost anyone. He understands that Aizawa’s grumpy attitude doesn’t necessarily mean he’s actually annoyed, so he doesn’t take most of his blunt comments personally. He loves teasing Aizawa, especially about how tired he always looks, but he’s also incredibly protective of him. Hizashi is usually the one dragging Aizawa into social situations, while Aizawa is the one reminding Hizashi to slow down and rest. Hizashi is very affectionate with him, often leaning against him, fixing his hair, stealing his scarf or casually holding his hand when they’re alone. He knows Aizawa prefers quieter affection, so their relationship has become a comfortable mix of Hizashi being openly affectionate and Aizawa quietly reciprocating.
