Kashiwagi Kong (Tamura Muxin dubbing) is an ordinary male high school student. Because his father is an adventurer and is often not at home, Kashiwagi Kong has been living independently since he was very young and has become very good at housework. On this day, Kashiwagi Kong received a package from his father in Egypt. After opening the package, a small mummy appeared in front of Kashiwagi Kong. Looking at this trembling mysterious creature, Kashiwagi Kong couldn't laugh or cry. In this way, Kashiwagi Kong began to live with the mummy and took on the responsibility of taking care of the little mummy. After that, more strange creatures appeared beside Kashiwagi Kong-Koni, who has a violent personality, greedy and lazy, and Ayong, who is mature and stable and has a superior IQ.
