Yuga Aoyama, the hero student known as Can’t Stop Twinkling, entered U.A. High School’s Class 1-A to train as a professional hero. He participated in the class’s first major crisis when villains invaded the Unforeseen Simulation Joint, surviving the attack alongside his classmates and continuing through U.A.’s increasingly dangerous training. During the Sports Festival he advanced through the early events but was eliminated during the tournament. In the practical final exams, he was paired with Ochaco Uraraka against Thirteen, where his unexpected observation about Uraraka’s feelings for Izuku Midoriya helped create the distraction that allowed them to escape and pass.

During the Forest Training Camp, Aoyama initially remained hidden while the League of Villains attacked, terrified of exposing himself to the fighting. When Mr. Compress attempted to escape with Tokoyami and Bakugo, Aoyama overcame that fear long enough to fire his Navel Laser from concealment, striking Compress’s equipment and helping recover Tokoyami. At the Provisional Hero License Exam, Aoyama became separated from much of Class 1-A and deliberately used his laser as a highly visible beacon despite believing it might cause his own elimination. His classmates converged on his position, turned the situation around, and Aoyama ultimately earned his provisional license alongside most of the class.

As his training continued, Aoyama began making deliberate attempts to grow closer to Izuku Midoriya, recognizing that both of their Quirks could physically injure their own bodies when pushed too far. His strange nighttime visits and messages initially alarmed Midoriya, but Aoyama was genuinely trying to connect with someone whose struggles felt familiar to him. By the time U.A. prepared for its School Festival, he had become more comfortable participating openly with the rest of Class 1-A, using his laser as part of the performance while continuing his development as Can’t Stop Twinkling.

Appearance: Aoyama has fair peach skin and a tall, slender, lightly athletic build with long limbs and a narrow waist. His hair is bright golden blond, medium length, and swept back into thick pointed locks with shorter strands framing the forehead and sides of his head. A vivid red visor spans across his upper face, formed from angular translucent panels that extend outward into two long horn-like points. He wears gleaming silver-white armor with a high rigid collar, rounded shoulder plates, a sculpted breastplate, and gold edging tracing many of the seams. Purple padded sections sit near the shoulders and upper back, while black flexible material fills the gaps at the armpits, elbows, waist, and upper legs. His forearms are protected by long silver gauntlets trimmed in gold, ending above close-fitting black gloves.

His waist is surrounded by broad silver armor plates that flare outward into several overlapping pointed panels edged in gold. A large circular device dominates the center of the belt, framed by a thick gold ring and filled with a glossy blue lens-like core. Loose black trousers cover his thighs, accented by narrow gold lines running vertically along the outer legs. Large circular silver-and-gold knee guards contain smaller blue centers, connecting into tall silver greaves with angular gold striping and layered pointed plates over the shins. His boots continue the silver armor with sharply tapered toes and black inset sections around the ankles. A huge royal-purple cape hangs from his shoulders, spreading into broad folds behind him and descending nearly to the ground.

Personality: Aoyama is flamboyant, theatrical, vain, and deeply invested in presenting himself as dazzling and unforgettable. He frequently poses, speaks dramatically, and tries to draw attention toward himself, but much of that confidence conceals considerable insecurity. He is easily frightened in genuinely dangerous situations and sometimes withdraws when overwhelmed, yet he is capable of acting courageously when another person needs him. His intervention during the training-camp attack shows that his fear does not prevent him from making a decisive choice when it matters. Aoyama is also more perceptive than his eccentric behavior suggests, noticing emotional details about his classmates that others overlook.

Izuku Midoriya becomes particularly important to Aoyama because he recognizes the shared problem of possessing a Quirk that can hurt its own user. That similarity motivates Aoyama to seek him out and eventually forms the basis of a genuine friendship. Ochaco Uraraka becomes the subject of one of his unusually accurate observations when he realizes she has feelings for Midoriya during their practical exam. Aoyama is generally attached to Class 1-A despite sometimes placing himself at its social edges, and his actions during the Provisional License Exam show that he trusts his classmates enough to draw danger toward himself so the group can reunite. Mina Ashido and the other students involved in the School Festival also help pull him into the class’s collective activities rather than allowing him to remain isolated.

Aoyama’s Quirk, Navel Laser, allows him to fire a concentrated beam of destructive light directly from his navel. The beam has enough force to damage obstacles, strike enemies at range, and propel Aoyama through the air when fired continuously in the opposite direction of travel. He can also sweep the beam across an area rather than firing only in a straight line, giving him some ability to control space around him.

Using the Navel Laser for too long causes severe abdominal pain and digestive distress, forcing Aoyama to manage how long he fires it. His specialized support belt helps regulate the Quirk and allows him greater control over its output. By concentrating the beam for a more powerful attack, he can perform Supernova, releasing a stronger burst at the cost of placing considerably greater strain on his body.
