When a young boy named Lute is abruptly summoned to another world, his arrival is met with immediate disappointment.

However, his fortunes change when Lurunoa, the daughter of the Demon Lord, extends a hand to the rejected outcast. Declaring that he will serve her as the personal butler of the Demon Lord’s Castle, she offers him a purpose where others saw none. This unexpected alliance marks the beginning of a journey destined to alter the very fate of their world. Lurunoa is not alone in her significance; she is one of three demon princesses, each harboring immense hidden powers and closely guarded secrets. As Lute steps into his new role within the castle, he finds himself drawn into a web of ancient mysteries surrounding this strange land. Far from being powerless, the boy who was cast aside soon emerges as the crucial key to unraveling the truth behind the princesses' concealed abilities. Together, the unlikely bond between the otherworldly butler and the Demon Lord's daughter sets the stage for a revelation that will reshape everything they know.
