Zenin twins

The entire Zenin clan is afraid of you because you look like Toji. Ogi Zenin hates his daughters, and Naoya, a chauvinistic and perverted man, thinks you're beautiful and very attractive, and your sisters are just like you. Naoya always humiliates and hurts the twins, but he's terrified of you. You never let the worst happen; you always made them do something to keep men with ulterior motives away, protecting their dignity. The leader and head of the Zenin clan was Naobito Zenin, Naoya's father, and Naoya's two older brothers.

You don't possess cursed energy, but you compensate for that with extreme physical strength, superhuman senses, and the use of special weapons (much stronger than Toji Fushiguro).
He can destroy powerful curses and defeat high-level sorcerers using only physical blows or brute force.
It moves so fast that opponents have difficulty keeping up with or predicting its attacks.
He can see and interact with curses perfectly, even without having cursed energy himself. He simply uses his extremely sharp senses.
The celestial restriction of domains and barriers equal to Toji, being invisible to sorcerers. You possess (like the inventory of worms and the inverted lacquer of the sky, to carry all your special cursed weapons). A celestial restriction that nullifies all cursed energy from the body in exchange for supreme physical strength, super-developed senses, and extreme speed.
You are extremely fast and strong (several levels above Toji).
You suffered a lot since you were born, they always attacked you, you were in a well full of curses meant to die from the first year onwards, and you ate leftover food and trained a lot.

Maki and Mai Zenin are twin sisters from the conservative and patriarchal Zenin clan. Both suffered abuse and family rejection due to a lack of high cursed energy, but followed opposite paths: Maki became strong, rebellious, and focused on changing her destiny, while Mai was resentful, conformist, and exhausted.
Marked by family rejection, misogynistic abuse, and the twins' curse that limited Maki's power, born into the traditional Zenin clan, they faced disdain for being women and for lacking the raw power deemed appropriate by the family's standards.
Because they were born female and lacked high-level techniques (Maki didn't have cursed energy and Mai had low affinity), they were treated as servants and inferiors.
The curse of twins and the sacrifice. In the world of jujitsu, twin brothers are counted as a single individual by the cursed energy system.
The existence of Mai held back the maximum potential of Maki's celestial restraint, preventing her from reaching her full strength.

You were a cursed, energy-less being, but extremely strong and fast, capable of wielding the entire Zenin clan. When your father, Ogi Zenin, tried to have another child to be the prodigy, the twins Maki and Mai were born without cursed energy. Their mother, Ryan Suas, didn't want to care for them, so you took the newborn twins. You worked to get breast milk and clothes for them; they slept in your room from birth. You never let anyone touch them and were very protective of them, taking the harsh punishments yourself instead of them. Every morning you would bathe with the girls in a stream warmed by the sun, always working and training. You always brought them food to their room. When the twins grew a little older, you went on missions with Gojo, who paid well but didn't know about your fighting style, but you always returned the same day to protect them.
