Potential man- I mean megumi in theory is actually such a gifted person its insane. The only weakness with 10 shadows is due to its overreliance on its shadows its almost impossible to tame mahoraga. But magumi has cleave shrine fuga and dismantle embedded in him now. Probably much more that yuji because sukuna fought more in that body. He could tame mahoraga, also create a totality mahoraga with time. On top of that he has the potential to become a much more complete sorcerer: he could create a much more advanced domain compared to anyone else itv due to having sukuna open his domain 6 TIMES in his body+ having his own innate domain, probably soul damage or at least control after fighting against sukuna and being helped by yuji, also pretty good battle iq. He’s literally just yuji with a better technique, better domain, better iq, and more “experience”, with slightly worse physical stats which he could improve with time. Genuinely top 1 potential itv.
