Sakura journeys to the capital with a noble mission: to protect the metropolis from the malevolent wrath of the Black Sanctum Council, following in her father's footsteps. Nonetheless, her expectations are shattered when she is not only tasked with harnessing her vast spiritual potency to operate a towering mech known as a Kobu, but also compelled to take the stage as a performer, since The Imperial Flower Division operates inconspicuously as an art theater. Her conspicuous blunder on stage and resulting damage to a production marks her out as an unwelcome presence, and she discovers that she must find a way to work with her new colleagues while simultaneously defying the foe and protecting the numerous sanctuaries that safeguard the city.
