[The Emperor's Daughter of Luck × Cross-border Raising of Cubs × The Chess Game between the Government and the Wild]
Suisui, the only heir to the emperor, was secretly sent to modern times by the imperial master for three years. He returned with memories of another world and became the precocious four-year-old favorite of the group.
The emperor's father was on tight guard, but she used the modern knowledge of "airplanes" and "gunpowder" to predict border crises.
The harem competes for support, and the powerful ministers force the palace, all trying to control the auspicious national destiny.
