Synopsis
Akebono-so, a mysterious apartment where each room connects to 12 countries in different worlds. The landlord's job was to manage the building and mediate the conflict between the inhabitants-that is, to resolve interstate problems. It was Kotaro Kuto, a high school boy, who took on the role of the outbreak of war if he failed.

While being surprised at the mysterious environment where a dragon will be there when the door is opened and a foreign princess will come to tea, he will carry out management work by making full use of his sharp brain and "a special skill".

What is the "problem between countries" that he will solve this time?
