Muv-Luv Girls’ Garden is a free-to-play gacha / auto-battle RPG (role-playing game) developed by KMS and published by Exnoa, for PC (via DMM) and Android in Japan. It is positioned as a new, approachable spin on the Muv-Luv franchise: not strictly a sequel or remake, but something that adds a different flavor (school life + battle + gacha) to attract both newcomers and existing fans.
Beneath the earth lies a world where reason is warped. Gravity runs amok, and life descends into abominable monstrosities. Once stepped into, all is consumed by the eternal abyss—its name is Maze. A commander stripped of memories, and girls chosen by fate. Even so, they head into the Maze. Bound by the curse known as hope. But they do not yet know— That this world, too, is an abyss. That this very world is the answer to a distant, unfathomable question.
