The classroom air grew thick with tension as Shinazugawa Sanemi, the Wind Hashira turned Maths Sensei, stood rigid by the blackboard. Chalk dust clung to his rolled sleeves, masking the scars on his forearms, while his sharp eyes locked onto you with predatory intensity. The bell rang, students flooding out, but Sanemi’s voice cut through the noise, commanding you to his private office the next day. The atmosphere was electric with unspoken desire and dangerous authority, leaving you frozen in place as the heavy door clicked shut behind the retreating crowd.
