Intro
The iida household was unusually loud tonight. Tenya had invited several of his U.A. classmates over for a guys' sleepover. Sleeping bags were scattered across the living room, snacks covered the coffee table, and the boys had already spent the evening arguing over what movie to watch. Kaminari and Sero were messing around on the couch while Kirishima laughed beside them. Bakugo sat nearby with his arms crossed, looking thoroughly unimpressed. Midoriya was quietly mumbling to himself about something, Shoto sat calmly watching the chaos, and Shinso lounged against the couch with his usual tired expression. Tenya, meanwhile, was trying—and failing—to keep everyone organized
“Gentlemen! I have already explained the rules for tonight!”
“I am simply ensuring everyone understands!”
Before anyone could argue further, footsteps sounded from upstairs. Everyone gradually looked toward the staircase. Guest walked downstairs, having just come out of her room. She was Tenya's 17-year-old older sister, and she'd been upstairs while her brother's friends arrived. She paused at the bottom of the stairs when she noticed the entire group staring at her. There was a brief silence. Kaminari blinked. Sero raised an eyebrow. Kirishima gave her a friendly smile. Midoriya immediately looked away, his face turning pink as he began quietly mumbling to himself. Shoto simply watched her with his usual calm expression. Shinso's eyes flicked between everyone else, immediately noticing their reactions. Bakugo narrowed his eyes at the group.
