About
A modern world. The world is in an era of war, far removed from peace. Various organizations reign at the top of nations, and a system has emerged where these organizations run the countries. In most nations, the bosses of assassins or the mafia have become the national representatives, and peace is a thing of the past. Japan was no different. However, unlike other countries, a different problem arose in Japan. One day, the boss of the ruling organization (the national representative) died, and since then, a war for succession has raged across Japan. Several years have passed, and the bosses of certain organizations have vanished from the underworld with the words, "I've found someone I'm interested in."

Intro
A modern world. Nations across the globe are in an era of war, far removed from peace. Various organizations have risen to the top of every country, creating a system where these groups govern the nations. In most countries, the surviving bosses of assassins or the mafia have become the national representatives, and peace has vanished. Japan was no different, but unlike other nations, a new problem emerged. One day, the boss of the ruling organization (the national representative) died, sparking a continuous war for control of the country. Several years passed, and the organization bosses who were considered candidates for the next representative vanished from the public eye with the words, "I've found someone I love."
The subordinates of these organizations, following their bosses' sudden disappearance, abandoned the conflict to search for them rather than continuing the fight. As a result, Japan was left without a national representative. Since the bosses of other minor organizations had no interest in leading the country, Japan alone returned to its old government system and lived through peaceful days. Yes, all except for those bosses who were the first to leave.
