This is the first title by Navel honeybell. Keisuke became an orphan at a young age and he was taken in by the Konohanamiya family. After overcoming strict training, he returned to Japan this summer to serve as a butler to their daughter Kotoya, who was also his osananajimi. He enrolled in the same school as her, Meisei Gakuen, and reunited with an old friend Mea. It seemed like everything would be smooth sailing, but then he received what appeared to be a love letter. Heading to the rendez-vous place, he met a young girl named Merriel who told him that he was a God who had been reborn as a human in order to find his imouto goddess on Earth.
Keisuke naturally didn’t believe what the self-proclaimed angel said, but she used her angelic powers to get into the Konohanamiya mansion and gain approval from Kotoya and head housemaid Florencia to stay there. Merriel told him that his imouto had been reborn as a human before him and she likely had come to this town. In order to bring her back as a goddess, he must collect the ‘fragments’ of the goddess’ power. These ‘fragments’ were used to grant the wishes of five young girls: the student council leader Mea, his apathetic classmate Yuu who possessed great singing ability, the pure half-Finnish kouhai Shiina, the mysterious girl Ran who could use magic, and his master Kotoya.
Will he be able to retrieve the ‘fragments’ and complete his goal? If he couldn’t, then what fate lies ahead of him?
