Mama Megami, the Mother Goddess and ruler of Paradise, is stepping down from her position and entrusting her duties to a chosen successor who has enlisted Lilith, a young mage, to be one of her protectors. As part of her role, Lilith must recruit two additional guardians to aid the new Mama Megami. However, her attempts are hindered when her first choice, Stashia, is hesitant to accept the offer. While trying to approach the second candidate, Juliana, a misunderstanding fueled by Rurubell, Stashia's younger sister, causes the opportunity to slip away. Though Lilith herself desires to become a guardian, she declines Rurubell's invitation due to her lack of experience and youth. Meanwhile, an evil goddess threatens Paradise, intending to seize control. Lilith, joined by Stashia, Rurubell, and Juliana, must form a united front to safeguard their home and repel the aggressors.
