[Mainly Jujutsu Kaisen] A Certain Scientific Quantum Girlfriend

A wanted scientist from Academy City changes her name and lives in Tokyo. Though she's obviously human, people keep mistaking her for a female ghost.

She thought she could live quietly in Tokyo, but after someone discovered her hiding place, she became the subject of an urban legend about a school ghost.

For the first 23 years of her life, she was always the one picking on others, never the one being bullied. But in Tokyo, she keeps clashing with that white-haired man and often ends up getting bullied.

Chiba Noe: What's going on? Do I have a grudge against everyone with white hair?

Accelerator: ???

Gojo Satoru: ???

Because she needs to constantly absorb quantum energy, Gojo Satoru becomes Chiba Noe's portable power bank.

Quantum people all say it's great.

The male lead is Gojo Satoru (probably). A crossover story. The heroine is a higher-dimensional being, something like a four-dimensional creature, and all curses are power banks to her, special grade or otherwise. So she has a pretty powerful cheat ability, but she's a blue-mana mage who uses mana even just walking around. Once her mana runs out, she starts losing HP.

And she can't beat Gojo Satoru, because her ultimate ability has a ridiculously long cooldown and costs a ton of mana.

Also a story where only the heroine talks about science.

Except Gojo Satoru isn't a three-dimensional being either.

My Tower of God fanfiction next door is called Even in Another World, the Gods Work Diligently. The male lead is Khun A.A.
