Marvel: I’m Hermione, From Hogwarts!

[Gender bender + Marvel + Harry Potter]

What do you do when you transmigrate to the wrong world?

Hermione from the Harry Potter world, but the person appears in Marvel.

A mysterious magic book lets Hermione shuttle back and forth between the Marvel world and the Harry Potter world.

...

Tony Stark: It's time to study anti-wizard armor.

Hermione: You mean that pile of junk that gets torn apart by whoever it's supposed to counter?

Hulk: Roar!!!

Hermione: Shut up, or I'll cast a spell to take off your underwear... I mean disarm you!

Gu Yi: A wizard outside the timeline...

Hermione: Say that again. I'm a witch!

Nick Fury: Where exactly do you come from?

Hermione raises an eyebrow: Me, Hermione, from Hogwarts!

[The protagonist is a scheming, acting-focused mastermind. The main worlds are Harry Potter and the Marvel Cinematic Universe. Other Marvel worlds will appear later, but they will not be fused.]
