A3! Season Spring & Summer

Izumi Tachibana arrives at the Mankai theater company searching for her father and instead finds a stage buried in debt and about to be demolished. She manages to win one final chance: produce a successful show within a month, restore all four acting troupes, and repay the company's debt within a year.

The problem is that the Spring and Summer Troupes barely have enough actors, and some members possess almost no real stage experience. Izumi takes over as director and begins gathering young men with completely different personalities and goals, trying to shape them into teams capable of facing an audience. Through rehearsals, clashes, and failures, saving Mankai becomes more than preserving a building; it means creating a place these actors can call home.
