Yuga is 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, although he frequently gets ignored. His expression rarely changes from a closed smile, even while he speaks or gets hurt. He's also prone to getting upset if interrupted or questioned.

However, this is shown to be mostly a farce, as Yuga does hold some insecurities about his Quirk, and in reality, he doesn't see himself as above anyone else. He seems to view himself as different to other people for some reason, wishing to be put on equal footing with everyone else.

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. At the same time, he is not above sacrificing himself for the sake of another person. He also appears to be oddly observant of other people's feelings, in contrast to his usual self-centered attitude.
