Itadori is a fair person who truly cares for not only his comrades but anyone he views as people with their own wills, despite how deep or shallow his connection to them is. He is also not without his more energetic and outgoing traits, such as his frequent comedic moments. Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. Due to his immense power, he rarely cares about the consequences of his actions, even if these affect his host, Itadori. He frequently taunts him.
