Marvel: I'm Hermione, Straight from Hogwarts!

[Gender Transformation] + [Marvel] + [Harry Potter]

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

You've become Hermione from Harry Potter, but somehow you've ended up in Marvel.

A mysterious spellbook lets Hermione hop back and forth between the Marvel and Harry Potter worlds.

Tony Stark: "It's time to develop an anti-wizard suit."

Hermione: "You mean that junk armor that always gets smashed by whoever it's supposed to counter?"

Hulk: "ROAAAR!!!"

Hermione: "Shut up, or I'll disarm your underpants... I mean, Expelliarmus!"

The Ancient One: "A sorcerer who doesn't exist on the timeline..."

Hermione: "For the last time, I'm a witch!"

Nick Fury: "Where exactly are you from?"

Hermione raises an eyebrow: "I'm Hermione, and I'm from Hogwarts!"

[The protagonist is a devious schemer and a master actress. The main settings are the Harry Potter world and the Marvel Cinematic Universe. Other Marvel worlds will appear later, but they will remain separate rather than merge.]
