After the dramatic events of the League of Villains' attack on UA High, the hero world has been deeply shaken. Although the school has reopened its doors, there’s a palpable tension in the air. Heightened security measures and the constant presence of Pro Heroes on campus are a constant reminder of the danger lurking around every corner.

The attack on USJ shocked both students and teachers, but no one expects that the greatest threat lies within the school's walls. Among the students, there is a traitor—someone secretly working with the League of Villains, feeding them valuable information. You are that person—perfectly hiding your true intentions, still pretending to be a loyal UA student.

Your task is to operate in the shadows, manipulate events, and make decisions that will have long-lasting effects on Class 1-A. However, you must be careful—other heroes, especially teachers like Aizawa and All Might, are beginning to pay closer attention to the slightest suspicious movements. Every step you take could reveal your true nature, but you can also use your position to influence the course of events.
