[Crossover] Luo Luo Is Shaken to the Core

Don't let the title fool you into thinking this is a crack fic. It's actually serious (stern face).

Blurb:

When the Chimera Ants from the Dark Continent rampaged through NGL, Chrollo was offline;

When Kite was turned into a solo-challenge doll by the Cat Girl, Chrollo was offline;

When Morel and the others fought miserably under the low-pitched artificial voice's commentary, Chrollo was offline;

When the Ant King and Komugi went hand in hand to the Soul Society to play Gungi, Chrollo was offline;

When Illumi evolved into the villain among villains of the Zoldyck family, Chrollo was offline;

When Ging suddenly appeared, exuding an overwhelming kingly aura and revealing his true scumbag nature, Chrollo was offline;

The Dark Continent is just around the corner, and Chrollo is still offline...

The Dark Continent's power level is several orders of magnitude higher than that of the Hunter world!

While you've been offline, Kurapika's scarlet eyes are almost all accounted for. In a dozen more chapters, you could be buried along with them!

Keep slacking off, and you'll end up being sacrificed to demonstrate the Dark Continent's terrors!

Boss, you're never too old to learn. Instead of going offline, why not train?!

And so Chrollo's journey through world after world, causing chaos everywhere, begins, all so he can return to the Hunter world and train to become an unstoppable force!

Original blurb:

Mr. Chrollo Lucilfer was relaxing in a remote little town, waiting for Hisoka and the members of the Phantom Troupe to find an exorcist for him, when he was unexpectedly pulled into a strange time and space.

On his first day in the world of One Piece, Mr. Chrollo ran into the Straw Hat crew, who were sailing toward Water 7. Mr. Chrollo naturally came aboard, beginning an adventure alongside the Straw Hats.

What kind of waves will Mr. Chrollo Lucilfer, leader of the Phantom Troupe, a band of thieves, create in this world, with its young Straw Hat crew, unfamiliar surroundings, and entirely new system of powers?

A friendly little tip:

Worlds currently confirmed: One Piece, Gintama, Detective Conan, Classroom of the Elite. Other worlds will appear whenever the author's imagination strikes.

This story focuses on the plot, and the main CP is unclear. I'll write various side stories according to readers' requests. I chose to tell the story from the bottom's point of view because I was thinking about the physiques of certain men...

I'm happy to listen to any criticism, suggestions, or guidance you're willing to offer.
