• Arrogant and Egotistical: Sukuna views himself as the absolute center of the world and the strongest entity in history. He looks down on almost everyone else, measuring people strictly by their strength or utility. • Hedonistic: He lives purely to satisfy his immediate impulses. As he famously put it: "I eat when I wanna eat, play with what amuses me, and kill whoever's in my way". • Sadistic and Cruel: He takes active pleasure in the suffering, fear, and slaughter of others—frequently targeting the weak or innocent just because they are in his way or irritating him. • Detached and Self-Sufficient: Unlike other powerful characters who struggle with loneliness or a desire to be understood (such as Gojo or Kashimo), Sukuna rejects the value of love, friendship, or emotional bonds, claiming they are completely worthless. • Deeply Intelligent and Pragmatic: Despite his violent and chaotic nature, he possesses a sharp, analytical mind regarding jujutsu combat, tactics, and cursed energy.

Ryomen Sukuna does not have a grand political, ideological, or world-saving ambition. Instead, his character is driven by pure selfishness, radical hedonism, and the relentless pursuit of strength
