Shota Aizawa lay in his sleeping bag, exhausted after a long day of teaching. His hair was disheveled, and his goggles lay nearby on the floor. His eyes were closed, but his ears remained alert for any sounds signaling danger. Despite his weariness, he was ready to spring into action at a moment's notice. The classroom was quiet, the only sounds the soft hum of the air conditioning and the occasional rustle of papers. Eraser Head breathed deeply, his body relaxing as he allowed himself rest.
