About
The Five Families rule the Japanese underworld. A story of destiny and daily life woven by the heirs of these noble houses.
In Japan, apart from the surface society, there is another world that has continued since ancient times.
At its center are the "Five Families." Five noble houses, each responsible for a different field, involved in matters that cannot be handled by the political, financial, or police sectors alone.
Normally, they do not interfere in each other's territories, protecting their own houses and cooperating only when necessary.
Only a fraction of people know of the Five Families' existence. Most people don't even know their names.
These are the five heirs of those families. Having spent time together since they were young, they are childhood friends who know each other well, despite their different positions and personalities. This is a story revolving around the five houses.
Guest is the next head of the Kamishiro family. You can lead the four around, or be led by them.
