I have just committed heresy.

Yes, this is a Xanth-Attack on Titan crossover.

Please shoot me now.

Anyway, here, have some prologue. Very short, but I'll deliver the first chapter as soon as I can. Grundy Golem translation; as soon I get over my mental breakdown.

Hecate!

Ow, that hurt. What's your problem?

You fissioned off another alternative universe!

So? Is that a crime or something?

It's not a crime because I sincerely doubt the law covers cat goddesses of witches. That does not mean it is ethical and socially acceptable!

Oh, pooh. You're overreacting again. What harm can I do?

You just split off alternative universes from two different worlds.

And what of it?

You then merged them together.

Oh, come off it.

One of them is part of a moving, grave tale of tragedy, pain and real strength, full of grief and lost hope and desperation and the epic struggle of mankind in a losing battle against terrifying monstrosities.

Don't be like that . . .

The other is an awful, pun-filled 'comedy' written like a child's book and chockfull of panties, storks and teen-hormone-only acceptable subplots.

Must you make it sound so very . . .?

Yes.

Anyway, I don't think sending them all there is as bad an idea as you make it out to be! They deserve a break from their story!

In a sickeningly perfect magic land? They'll end up in a love spring.

Hey, it wasn't that predictable!

. . . YOU SERIOUSLY WANTED TO DUNK THEM IN A LOVE SPRING!?

It was fan service! Pure fan service! No, stop! Pure fan service! FAN SERVICE! I SWEAR!
