Event Horizon: My Hero Academia x Voidbound

When two worlds with the same purpose to protect those who can't walk apart, the story changes in how they fight and what it costs.

In Musutafu, the students of Class 1-A and Izuku learn that some victories take memory, trust, and the bonds they rely on. In Tsukuyomi, Ren, and his class hold the Void at bay with methods forged by another culture and scars Musutafu doesn't yet understand.

Through the first arcs we follow both journeys in parallel, chapter by chapter, until the pressure of a wider catastrophe forces both sides to meet. When the boundary finally breaks, what happens to heroes who promised the same thing but grew up in such different lives and societies?
If you like tense action, real consequences, and friendships tested by the unknown, climb aboard. It's a long journey.
