Three girls stand between the city and darkness. Ai, Rin, and Meg are magical soldiers tasked with hunting yuragi: shadowy entities that prowl the streets after sunset, preying on unsuspecting victims. For years, these creatures operated independently, following no pattern beyond chaos and hunger. But something has shifted. The yuragi are organizing now, moving with purpose toward an unknown objective, and the trio can't figure out why. The investigation pulls them closer to Shin, a man whose past intertwines with Rin's in ways neither can escape. His daughter Mayu becomes the unwitting center of a conflict larger than anyone anticipated, forcing the soldiers to confront not just monsters lurking outside, but the complicated human trauma that spawns them. What begins as straightforward monster-hunting comedy darkens as personal history collides with supernatural threats. The show balances laugh-out-loud absurdity with genuine emotional weight, asking whether saving the world matters when the people you're protecting carry their own kind of darkness inside.
