MHA x UMNV: The Void Between Heroes

In one society, children grow up dreaming of becoming heroes.
Quirks shape careers, laws, rankings, and public expectations. U.A. High trains its students to protect civilians and become symbols people can trust.

In another society, abilities are called Natures.
Crystals, humans, hybrids, and dangerous creatures exist under fragile rules. Shinkai Academy prepares its students for missions, containment, and threats hidden from ordinary people.

For now, both societies remain separate. Their students fight different battles. Their teachers follow different laws. Their enemies move across different paths. Soon, a single decision will connect both sides.

U.A. and Shinkai will be forced into a union neither society fully understands. Quirks and Natures will exist under the same roof. Heroes will meet Guardians. Humans will train beside hybrids. Old rules will stop working.
Some will see the union as progress. Others will see a threat. Trust will take time. Rivalries will grow. Every student will need to decide what being a hero means when two systems of justice collide.

Two societies. Two forms of strength.

One future they must face together.
