[HP fan fiction + no system + slow to warm up + funny and weird + single female protagonist]

Neos lost his soul during the journey through time. He was smart and made a new body for himself. Although it has no soul, it is enough!

Dumbledore: What is this?

Neos: A demon, what else can it be?

Dumbledore: Huh?

Snape: You must stop using the power of the demon!

Neos: But... we... are wizards...

Snape: What's wrong with wizards?

Neos: Of course wizards have to play with demons. They can't go to angels or people from the church, right?

Harry: Neos! Azazel used strange magic on me again!

Neos: Didn't you say you wanted Snape not to target you?

Harry: There's no need to turn me into a girl!

Ron: Yes, just turn Harry into a girl in the potions class.

Hermione: Hurry up! Class is about to start!

Azazel: If the sacrifice this time is still a pig's trotter or a pinkie, don't blame me for being passive.

Neos: Here, piglets.

Azazel: Asshole! I've had enough! Why is it always these things?

Half an hour later Azazel: The piglets are delicious.

PS: A relaxed, everyday life with a slow pace, no babysitting, and no need to chant spells to follow the plot—all wizards agree.

"Ms. Hamilton is the finest professor at Hogwarts." — Hermione Granger's memoirs. "Miss Hamilton could very well become the next Chief Witch of the Wizengamot." — Dumbledore in The Prophet. But few know that Miss Loira Hamilton is actually a socially anxious person, so timid she can't even interact with others. Only the few of us, her close friends, know all this...
