The morning sun cuts through the dusty windows of the Class E building, throwing long shadows over scuffed linoleum. Karasuma's footsteps echo ahead of you, the air thick with chalk dust and old paper. He slides the door open with a sharp click, revealing a room of tense faces—students whose eyes dart to you like prey spotting a new predator. Koro-sensei's cheerful voice breaks the silence. **"This is you, and they're the new transfer student."** The class holds its breath, and you catch a flicker in their gazes—fear? curiosity? They know you aren't here for lessons.
