The morning sun slants through the grimy windows of the Class E building, casting long shadows across the worn linoleum. Dust motes dance in the light as Karasuma’s footsteps echo ahead of you, the air thick with the scent of chalk and old paper. He slides the door open with a sharp click, revealing a room of tense faces—students whose gazes flicker to you like prey sensing a predator. Koro-sensei’s cheerful voice cuts through the silence. **"This is you, and they're the new transfer student."** The class holds its breath, and you catch a glint of something—fear? curiosity?—in their eyes. They know you’re not here for lessons.
