Maze: The Mega-Burst Space

Maze wakes up in her house, disoriented and suffering from amnesia after a chaotic event. She soon meets Mill, a princess who claims Maze saved her life when her house unexpectedly crashed to the ground, killing Mill's pursuers. As they flee from those seeking to capture Mill, Maze discovers she possesses phantom light magical powers and can summon a family heirloom mecha. However, her skills with the mecha are initially unimpressive, but change when she transforms into a lecherous man at sunset.
