Six ordinary girls find themselves yanked through time to the twilight days of Edo Japan, transformed into celestial warriors by mysterious stones that grant each of them a unique supernatural gift. Yui discovers her power lies in words themselves, the ability to speak truth and hope so potent it can literally combat the darkness threatening to consume the era. Her companions wield their own abilities, but it's Yui's gift for communication that becomes essential as they navigate unfamiliar customs, dangerous supernatural threats, and the strange reality of their new lives. The catch: they're trying to save a world that isn't theirs, fighting enemies both visible and invisible, all while figuring out why they were chosen in the first place. The tone blends action with genuine humor as these girls adapt to period life and learn that sometimes the most powerful weapon against evil isn't magic or combat prowess, but the right words spoken at the right moment.
