canon things about jjk that alot of ppl dont really understand but is helpful to remember:
SUKUNA IS NOT A CURSE. he is a human deformed from eating his twin in the womb. he sees himself as a curse due to alienation and self hatred
the six eyes are a GOJO CLAN EXCLUSIVE TRAIT. it can only be born in the gojo clan and two users cannot exist at the same generation
toji can't get drunk or high. heavenly restriction specifically forbids it (he also cant EXORCISE curses, he can see them just fine)
all reincarnated sorcerers (kashimo, choso, sukuna) have knowledge on the modern world based on their vessels
Sukuna speaks very pompously in canon, and has interest in archery, haikus, and flowers. hes a heian era nerd
cursed energy is what creates curses and they can only be created by non-sorcerers. curses are created from raw cursed energy, they were never human (other than choso and yuji post eating his brothers unfortunately)
