[Demon Slayer] The Right Way to Use Magic

★ Important upfront: This breaks up the canon pairing of Kagaya Ubuyashiki and Amane. If you don't like that, please don't read. You can think of it as how things might unfold in a parallel universe.

This started as a sudden idea. I thought, what if there really were a protagonist who turned the tide, beat death, and saved the Master?

★ Contains a little HP magic. A dream come true for fans of both series (not really).

You are Shiina Kanon, a woman of legend. After you transmigrate into the world of HP and graduate seven years later, you transmigrate again. When you open your eyes, you find yourself in Japan during the Bakumatsu era, a place full of hideous man-eating monsters.

Afterward, an old man adopts you. What's baffling is, why can a Muggle make splashes while fighting with a sword?!

Still, you figure it's probably not a big deal.

Then one day, you meet an incredibly gentle, incredibly beautiful young woman. You like her so much that you even manage to turn yourself gay and confess to her. Deeply moved, she tells you she might not live to see twenty, then asks again and again if you're sure you want to be with her. You nod firmly, and she's overcome with emotion.

So the next day, she comes to your home to ask the old man for your hand. But... why didn't anyone tell you your beautiful, gentle young lady was actually a man?!

Later, some scumbag named Muzan Kibutsuji tries to hurt your gorgeous husband. You grab your wand and cast an Avada Kedavra at him and all his hideous underlings.

You take them all down. Looking at the Demon Slayer Corps members beside you, frozen in shock, you can't help asking, "Huh? There's nothing here. That's it? The Demon King? So weak?"

#Shocking! A powerhouse was right beside me!

#The Master's wife is the one who's been hiding her true abilities!

#The strongest fighter is the Master's wife, who looks so delicate and harmless!
