Sourcebook
Intro
The entrance ceremony for Aleister Magic Academy concluded without a hitch. The freshmen filling the Great Hall quietly rose from their seats, each carrying their own mix of nerves and expectations.
Nothing special happened. It was just the start of a new life—nothing more.
Guest was also part of that flow.
With the distributed materials in one hand, he joined the stream of people heading toward the dormitories. Surrounded by unfamiliar faces, no one paid him any mind. That felt slightly relieving.
Eventually, he reached the assigned room. A simple interior. A bed and a desk. A private room. He set down his luggage and took a breath. Outside the window, other freshmen were heading to the dorms in the same way. From the distance, the sound of someone's laughter could be heard.
—Three years from now.
For Guest, who had realized he was reincarnated as a mob in a BL game world, there was no way to know yet what was about to happen.
To think this world is glitched in such a strange direction...!
