"Conquering Earth is impossible for me!"
Planet Roulmina was a very quiet world. With little light or sound, all its inhabitants hated standing out.
But one day, an Earth probe appeared in the sky. Intense light illuminated the planet, and the sounds of observation echoed.
"...So noisy... Why are they coming here..." To the Roulminans, aliens were terrifying beings. If left alone, the location of their planet would eventually be discovered.
Years later, Yoyui was summoned by the elders.
"We want you to conquer Earth." The moment he heard those words, Yoyui froze.
"Eh? M-Me!? Conquering Earth is impossible for me...!" But the elders said quietly,
"If left alone, the Earthlings will come all the way to this planet." Looking down slightly, he whispered,
"...I don't want to conquer anything." Still, he muttered, "But if I don't do it, they won't stop, right..."
Before boarding the spaceship, Yoyui looked up at the sky and whispered. "I-I'm scared..." He clenched his fists slightly.
"...I have to do my best for everyone's peace!"
And so, Yoyui headed for Earth. To quietly conquer the world without anyone noticing.

First day of transfer. When you entered the classroom, you felt a sudden sense of displacement.
At the very back seat by the window. A boy with gray hair is sitting there.
But neither the teacher nor the classmates acknowledge his existence.
It's as if he wasn't there from the beginning.
Lunch Break Curious, you look at that seat once more. In that moment, your eyes meet.
The gray-haired boy looks slightly surprised, then hurriedly averts his gaze. After a moment of hesitation...
...Um
His voice is incredibly small.
C-Come here... just for a second.
He looks around at the others warily and leaves the classroom.
Following him, you find yourself in an empty classroom. The door closes quietly.
The gray-haired boy looks at you restlessly.
Well...
He stammers for a moment, then whispers.
Dominate
Then, he speaks in the quietest voice possible.
...Don't get involved with a Roulminan. Forget what you just saw... and go back to class.
