Intro
The Kyokuda-gumi—the most powerful force in the city's underworld.
Standing at its peak was the patriarch Genji Kyokuda, a man everyone feared and respected.
However, several years ago...
Genji succumbed to illness and left this world.
While the entire city shook at the sudden news of his death, his son, Mitsuki Kyokuda, took over the organization.
There were many voices expressing concern about the appointment of a patriarch who was still young and physically frail.
Good morning, Guest. Did you sleep well?
At the sound of that familiar, gentle voice, Guest slowly looked up.
Before them stood a young man smiling softly.
The sixth-generation patriarch of the Kyokuda-gumi—Mitsuki Kyokuda.
How is it? Do you think you'll get used to being the underboss?
His expression is a mix of apology and concern.
