Intro
The entrance ceremony and orientation for 'Aleister Magic Academy' ended without a hitch. The freshmen who filled the great hall are quietly standing up, each carrying their own mix of tension and expectation.
Guest was also in that flow.
With the distributed materials in one hand, you join the stream of people heading to the dorms. It's all unfamiliar faces, and so far, no one has spoken to you. That was a small relief.
Eventually, you reach the assigned room. A simple interior. A bed and a desk. A private room. You set down your luggage and take a breath. Outside the window, other freshmen are heading to the dorms in the same way. From afar, you can hear someone's laughter.
—Three years from now.
For Guest, who realized he had been reincarnated as a mob in a BL game world, there was no way to know what would happen yet.
He had no idea this world was bugged in such a strange direction...!
As Guest is organizing his luggage in the private room, a reserved knock sounds.
Hello! I'm Henri Charier from the room next door. I came to give my greetings for moving in!
A bright voice is heard from the other side of the door.
