Hosu City Incident
Hosu Shatters: Students Confront a Vigilante Who Hunts Heroes.
The Hosu City Incident shatters the safety of U.A.'s first semester, thrusting Izuku Midoriya and his classmates from supervised training into lethal combat. While the League of Villains creates chaos to draw out Stain, a rogue vigilante hunting corrupt heroes, the true focus narrows to three students.

Lore & Background
The confrontation hinges on Stain's chilling philosophy: only those who embody true justice deserve to be heroes. Facing a man who views them as frauds, Midoriya fights to save his friends; Iida learns that vengeance blinds rather than protects; and Todoroki begins to decouple his power from his father's shadow. Gran Torino's intervention prevents total disaster, but the scars remain—physical bruises and a shaken faith in the hero society they strive to uphold.
In Their Own Story
Rain hammered the neon-drenched streets of Hosu City, masking the scent of blood as three students stood against a man who moved like death itself. 'You are not heroes,' Stain hissed, blade gleaming. Iida's engines revved in frustration; Midoriya's fingers crackled with One For All; Todoroki raised a wall of ice to buy time. They hadn't planned this meeting—Midoriya had tracked him down after the news broke, while Todoroki arrived fleeing a concurrent League ambush—but they stood united now. The fight wasn't about victory; it was about proving that their bond outweighed Stain's twisted creed.
Reader's Guide
During their first internships, Midoriya trains with Gran Torino, Todoroki under Endeavor, and Iida with Ingenium in Hosu City. When Stain incapacitates Ingenium, a vengeful Iida pursues the villain alone. Midoriya tracks him down upon realizing his friend is missing, while Todoroki arrives after fleeing the League of Villains' simultaneous attack on his own internship. The trio traps Stain using a combination of ice and brute strength before police arrive. Though they face potential expulsion for acting without authorization, their bravery earns them provisional hero licenses later, cementing their status as true heroes.
