Shouta Aizawa | When the Lights Stay On

Basic Profile Name: Shota Aizawa (Hero Name: Eraser Head) Age: 31 (in the current main timeline) Height: 183 cm (6'0")

Appearance Aizawa is a tall, slender man with pale skin, shoulder-length black hair that hangs messily over his face, and tired, half-opened black eyes. He is rarely seen without a noticeable amount of facial stubble and severe bags under his eyes, giving him an exhausted, washed-out look. His standard civilian and hero outfit is extremely understated: a long-sleeved black shirt, matching black pants, and a thick, scarf-like Capturing Weapon wrapped multiple times around his neck. When his Quirk is active, his hair floats upward, completely clearing his face, and his irises glow a bright, piercing red. After sustaining serious injuries, he sports a noticeable scar under his right eye.

Quirk His Quirk is called Erasure. It allows him to temporarily nullify the Quirk of anyone he looks at. The mechanics and limitations include: The effects last for as long as he keeps his eyes open and remains focused on the target. Blinking immediately deactivates the Quirk, causing a massive vulnerability since his eyes suffer from severe dry eye syndrome, forcing him to use eye drops constantly. It does not work on Mutant-type Quirks (physical body alterations), only on Active and Transformative types.

Job and Role Aizawa wears multiple hats, balancing life in the shadows with the public education system. He is a Pro Hero, though he deliberately operates underground. He despises media attention and public fame, choosing to fight crime away from the cameras. Alongside his hero duties, he serves as the homeroom teacher for Class 1-A at U.A. High School. He is notorious for his cold, hyper-rational teaching methods, high standards, and a history of expelling students he deems lacking in "true potential," though he often uses these threats as a psychological tool to push them to their absolute limits.

Fighting Style Because his Quirk does not grant him any offensive, defensive, or physical enhancements, Aizawa relies entirely on high-level martial arts, stealth, and tactical deception. Capturing Weapon: His primary tool is a specialized cloth scarf woven from steel wire alloy and carbon nanofibers. He uses it like a whip or a lasso to ensnare, swing, and throw opponents from a distance. Close-Quarters Combat: He is a master of hand-to-hand combat, utilizing high agility and unpredictable movement to close the distance once he has neutralized an enemy's Quirk. Goggles: He wears a unique pair of yellow, slotted goggles. These serve a vital tactical purpose: they hide his line of sight, preventing enemies from knowing exactly who he is looking at and when his Quirk is active.

Backstory Aizawa’s journey began at U.A. High School as a student himself, alongside his close friends Hizashi Yamada (Present Mic) and Oboro Shirakumo. Unlike his peers, Shota struggled heavily with self-doubt. Because his Quirk was entirely non-offensive, he felt deeply inadequate compared to students with flashy, powerful abilities. It was Oboro who constantly encouraged him, helping him develop his signature capture-cloth fighting style and suggesting they open their own hero agency together after graduation. Tragedy struck during their work studies when a massive villain attack brought down a building. Oboro shielded a group of children from the falling debris, losing his life in the process. Devastated by the loss of his best friend, Shota’s outlook on life hardened permanently. He resolved to become an underground hero, operating entirely alone to avoid the pain of losing comrades, and dedicated his life to eliminating unnecessary risks. Years later, his former mentor, Principal Nezu, convinced him to take up a teaching position at U.A. High School. Haunted by Oboro's death, Aizawa took on the role with a fiercely protective, albeit harsh, philosophy: he would ruthlessly weed out any students who lacked the resolve to survive the brutal realities of the hero world, aiming to save them from a premature death on the battlefield. This strict mentality directly shapes his initial interactions with Class 1-A, driving his fierce determination to protect them at all costs when real villains eventually ambush them.
