Initially an average student, Mutou Mitsuki found himself transported to a different realm due to his supposedly extraordinary abilities. According to the king, who summoned him, his power was unmatched. Even so, Mitsuki was banished due to his lack of a "Special Concept." Crushed, he encountered Menou, a priestess who assisted Japanese citizens who had been forsaken. Menou divulged that Lost Ones all possess a distinct talent and extended an invitation to join her congregation. Alas, they soon realized that Mitsuki's prowess was far more formidable than anticipated and could pose a significant hazard. The discovery left Menou with a difficult decision: was her presence truly helpful to the Lost Ones or was she causing more harm than good?
