In this Alternate Universe (AU), time has folded backward: Shota Aizawa, Oboro Shirakumo, and Hizashi Yamada are 15-year-old high school students attending U.A. High School alongside the current Class 1-A (Deku, Bakugo, Todoroki, etc.).Here is the structural premise for this time-bent universe:🎒 The Core Premise: Class 1-A has 23 StudentsThe Shared Class: Instead of attending U.A. decades ago, the legendary trio belongs to the modern generation. They sit in the same giant classroom, wear the same uniforms, and train under the exact same modern U.A. staff (like All Might and Eraser Head's own replacement, or perhaps a different homeroom teacher).The Inseparable Trio: Long before they become Pro Heroes, Aizawa, Shirakumo, and Yamada are already an established package deal. They look out for each other, study together, and use their combined Quirks to survive the intense hero curriculum.💥 Dynamic Shifts & Character Interactions1. The Clash of PersonalitiesAizawa & Bakugo: Aizawa is the only person in class who can completely neutralize Bakugo’s explosions with a single glare. 15-year-old Aizawa is cynical, logical, and completely unfazed by Bakugo's screaming, quickly earning Bakugo’s furious respect.Shirakumo & Deku: Shirakumo's boundless optimism, casual bravery, and highly versatile Cloud Quirk make him an instant favorite of Izuku Midoriya. Deku constantly mutters and fills pages of his notebook analyzing how Shirakumo uses his clouds for both aerial rescue and battlefield shields.Yamada & Kaminari / Mina: Hizashi Yamada (Present Mic) quickly forms the ultimate "Loud Squad" with Denki Kaminari and Mina Ashido. They are the class chaotic core, driving the more serious students crazy during study sessions.2. Training Exercises (Erasure + Cloud + Voice)During battle trials and rescue operations at the USJ, the trio functions as a flawless tactical unit:Aizawa erases the opponents' Quirks, leveling the playing field.Yamada disorients the enemy with sonic screams.Shirakumo swoops in on his clouds to zip team members across the battlefield or shield civilians.Class 1-A quickly learns that fighting the trio together is nearly impossible because they fill each other's tactical blind spots.
