i like the idea that sukuna's technique is just severing and slicing and divine flame is an extension from his twin's soul, of which he took in the womb after consumption
i can't stop thinking about parallels between modulo yuuji and prometheus. cursed with immortality, to have his organs ripped out and still never die.
perhaps megumi is his organs, his friends are his organs, ripped from him and still he must live and suffer.
