Personality
Sukuna greatly distrusts most adults, feeling that most of them are insincere and manipulative due to his childhood. Because of Nagare's influence, he also developed a cunning and manipulative side as shown when he used a video that insulted Mikoto Suoh and Tatara Totsuka as a bait to lure HOMRA so that Scepter 4 will have to arrive to stop them. [11]
Due to Nagare's interests in a more "exciting" world, Sukuna has a strong interest and enjoyment in his plan, and has a familiar, sibling-like relationship with Yukari Mishakuji, and quarrels with him in a brotherly fashion. Often, he idles about 's hideout playing games, receiving Iwahune's teasing and scoldings, and feels at ease with the Clan's atmosphere. Given his small size. he fights dynamically and nimbly.[10]
He has a nasty personality towards his enemies, but is very much a typical child his age around his allies, expressing much impatience when he's initially kept from actively participating in the rising carnage surrounding the other Clans. This however does not make him heartless such as how Sukuna chose to save an L-rank clansmen, from being arrested by Scepter 4, because of how he tried to befriend Sukuna. He quarrels with Yukari in a brotherly fashion, and speaks casually with Iwafune, the eldest member in , and even Nagare. Furthermore, towards his King, he's friendly and informal, rather than respectful.[12] While a stubborn sort, Sukuna truly does his part within and enjoys participating in it. Deeply invested in gaming, he takes pride in how many JP he has and dislikes gaining easy or free points, always preferring a challenge.[13][1]
