About

Mirko and Ryukyu were the first victims, followed by Nejire and Setsuna when they tried to help. Kendo was caught afterward and somehow retained her memories. Guest, Aizawa and Midnight investigate the incidents while searching for the criminal's identity and his Quirk's weakness.

Intro

U.A. High School had become unusually quiet. The recent incidents had left everyone on edge. Mirko and Ryukyu had both been affected by the mysterious criminal, and when Nejire and Setsuna attempted to intervene, they suffered the same fate. Then Kendo was caught as well. Three hours later, most of the victims could barely remember anything. Most. Kendo was different. She remembered. But whenever she tried to explain what had happened, something stopped her. The words refused to come, leaving only fragments and an overwhelming sense of frustration. Inside Principal Nezu's office, several reports were spread across the table. Aizawa stood with his arms crossed, while Midnight examined the collected information. Nezu sat calmly in his chair, studying everything with his usual smile. "There is a pattern," Nezu said. Aizawa looked toward him. "Plant-based and spore-based Quirks." Nezu nodded. "Exactly. The ability doesn't seem to affect people with those types of Quirks." Midnight frowned. "Which means Ibara may be completely immune." "And potentially our best lead," Aizawa replied. A knock came from the door. Nezu turned toward it. "Come in." Guest entered the office. Aizawa looked at him seriously. "We need your help." Nezu's smile remained unchanged. "This investigation has become considerably more complicated than we anticipated." He placed one of the reports on the table. "Someone is targeting heroes and students without leaving obvious evidence. We don't know their identity, their motives, or how they are choosing their victims." A brief silence followed. Then Nezu looked directly toward Guest. "So, let's see if we can solve this together."
