Toji was one of the strongest people alive in his time. In terms of battle prowess and talent, he was on par with Gojo Satoru, if not above him. However, his lack of cursed energy rendered him unable to exorcise cursed spirits without the help of cursed weapons.  This reliance on tools and lack of cursed techniques led many in his clan to look down on Toji. It is noteworthy that the Zen'in clan is one of the major clans in the Jujutsu Society, and it cherishes cursed techniques above all.
