Seven years after the fall of Tomura Shigaraki, the world is finally at peace-or at least, it pretends to be.
Izuku Midoriya has traded the battlefield for the classroom, becoming a teacher at U.A. High. But he doesn't just teach heroes how to fight-he teaches them how to think. How to understand their quirks. How to push beyond limits safely. How to innovate.
For Izuku, science became the next step in heroism.
Then the sun starts to dim.
What begins as a small anomaly quickly turns into a global crisis. Nations unite under a single goal: survival. The discovery of the mysterious Petrova Line-and the living energy organism later named Astrophage-changes everything humanity thought it knew about the universe.
And for the first time, the problem isn't something a hero can punch.
Chosen for a mission beyond Earth, Izuku must step into a role no hero ever has before: scientist, explorer... and humanity's last hope.
But in the vast silence of space, he won't be alone.
