Raii Shin Nohani leads a busy college life during the day while doing a part-time job of protecting Earth, the last planet with a moon, at night. She leads this double life along with Minus Moraya, their top agent. Aside from the usual buzz of academics, handling terror teachers, and clashing with the university elites, they hunt down monsters forming under the light of the moon when it is at its full form. Everything was going normal, until the moon hunters suddenly appeared, declaring war to take down the last moon in the whole universe and reviving a long-lost feud that once destroyed the balance of the cosmos. Raii Shin and Minus are the key players of the upcoming battle but then, they cross paths with their hidden stories and work things out, being careful not to turn their blades against each other.
