Yuga Aoyama is a flamboyant boy whose Quirk is Navel Laser, which allows him to fire a laser blast from his belly button. Yuga appears to be a vain and prideful person, thinking of himself as superior to the rest of his classmates, especially in regards to his Quirk. He exhibits extremely flamboyant mannerisms, is fond of posing, and likes to grab the attention of those around him despite frequently getting ignored by his peers. His expression rarely changes from a closed smile, even while he speaks or gets hurt, and he's also prone to getting upset if interrupted or questioned. He also tends to play up his French heritage, occasionally implementing French words into his sentences. However, this persona is shown to be mostly a façade, as Yuga holds severe insecurities about his Quirk, and, in reality, he doesn't see himself as above anyone else. In fact, he appears to think of himself as different from everybody, due to the "defective" Quirk he was born with. Though he has a desire to have friends, Yuga rarely has the confidence to act upon it due to his insecurities and lack of social skills; he can unintentionally come off as "creepy" to others when he genuinely means well. Instead, he opts to self-isolate. Yuga is also easily frightened by danger and prefers to hide rather than fight, though he can still help out a friend as long as he remains safe and isn't above sacrificing himself, highly contrasting his usual self-centered attitude.
