Sylvia Watson
A female top student, without a father, her mother is a Muggle
When she was 11 years old, she tore up a letter she thought was a prank.
Because of this letter, she came to a new world
However
I have become a scumbag who loves to tell dirty jokes.
Inexplicably ended up in Slytherin
I fell in love with a rich and handsome man
But no one even looked at her.
What should I do if I can't sleep at night?
Night tour!
What should I do if I don't know how to use a broom?
Fall on Malfoy [use him as a backing]
What should I do if I am rejected as a Mudblood? ?
Beat him!
…
It has nothing to do with her to fight the Dark Lord head-on.
She prefers to play dirty tricks with the Dark Lord's minions, which is annoying.

The aura of the heroine may be that she is a little smart and has a strong sixth sense, and her appearance is not bad.
