I Become Alaya in a Crossover World

Cheng Yang was sold by Mother Earth to another world to become an Alaya, responsible for directing the planet's heroes and defeating the invaders who would arrive in the future.

But Cheng Yang took one look and saw that this was just a slice-of-life school comedy crossover world. Where were these heroes supposed to come from?

Then he realized that if there were no heroes capable of saving the world, well, he could make some!

And so, all kinds of strange videos began appearing online.

In the videos:

Hachiman Hikigaya: "My mother once said that I am the man who walks the path of heaven and commands all things!"

Miyuki Shirogane: "You will never reach the truth of death. This is Gold Experience Requiem!"

Kirito: "Senpai Heathcliff, why are you just standing there? Have you really betrayed us?"

Sakura's grandpa, Tomozou Sakura: "Back when I was young, I was pretty strong, you know."

Kaguya Shinomiya: "He said, 'Now's our chance.'"

Yukino Yukinoshita: "Dissolve everything, Benten's Five-Stringed Biwa!"

Utaha Kasumigaoka: "I'll decide how this story ends! Blazing Sword Draw!"

All the stars of the videos: "It's a rumor! It's all a rumor!"

When the invading army finally arrived:

The crowd: "What happened to it all being rumors? You people are the worst!"
