#curse techniques

I think that curse techniques are only "inherited" because the generational trauma that causes them keeps repeating within those families. (and just because someone faces the same experiences doesn't mean that they'll have talent as a sorcerer)

Gojo's infinity, not being able to be touched, because he grew up so isolated. locked away from the world, unable to connect with others bc of that his entire life. being pushed and pulled around by others, and hollowed out. oh my god he had a freeze response. being able to see everything and do nothing about it. I also think the Gojo clan has the most incest abuse, and his inability to ever process that means he can never be fully honest with a woman, that he's in denial of what Ui Ui was going through, and in the end [big manga spoiler: bc Ui Ui was working w Mei, he confiscated Gojo's body in Shinjuku before Sukuna would have healed him out of boredom. would have coughed up his own fingers to feed Gojo. This would have saved Fushiguro. Gojo could have been the hero, if he were honest with himself.]

The ten shadows technique might develop after losing guardians, one after the other, there's grief and shadows and you're forced to adapt and become your own parent.

Resonance makes sense for Nobara, who felt the pain of others, related to them, despite the distance. How she grew up in the countryside but felt homesick for the city. Her grandmother likely felt the pain of long distance as well.

Kamo clan is harder to analyze since the most notorious event was actually done by Kenjaku, but Fushiguro even mentioned that blood manipulation is fitting for a clan so obsessed with bloodlines (paraphrasing bc I forget exactly, edit later it's in the exchange event arc).

and Sukuna’s CT of slicing and burning — it is heavily implied that Kenjaku did to Sukuna, what Sukuna did to the spirit which ate his finger in the detention center. This might develop his slicing technique. And the burning — going into the Ainu history, how they were displaced from homes burned away. Their tattooing technique involved slicing the skin and burning materials for the pigment. And the sound of metal like that is sacred... I rly do think he gave himself those tattoos with his CT, in a moment like Gaara (from Naruto), a heartbroken attempt to show himself love.

Itadori Yuuji is a descendant of the Uzumaki clan. His physical strength, durability, cursed energy (chakra but weird) reserves, and ability to host (seal) another being inside of him are all characteristics of the Uzumaki clan. Also the pink hair and the loud, sunshiny attitude.

Fushiguro Megumi is a descendant of the Nara clan and the Inuzuka clan. His technique, the spiky dark hair, and the general air of annoyance around him are all from the Nara clan. The fact that the Ten Shadows are mostly animals, with the ones Megumi likes the most being dogs, is really all I got for this one.

Kugisaki Nobara is a descendant of the Yamanaka clan. Her loud (angry, brash) attitude, emotional constipation, and general badassery are all seen in members of the Yamanaka clan. Also her Straw Doll and Resonance techniques both connect some part of a person with Nobara, which gave the same vibes as the Yamanaka clan jutsu.
