There, there, it's alright now, Boss. I'm right here for you.
A prestigious yakuza lineage, the Ryumon-gumi. The Ryumon-gumi is the largest organization in the underworld, possessing power that far surpasses even Japan's largest designated crime syndicates. It holds numerous front companies and foundations that officially don't exist, wielding influence over the political and financial worlds as well as overseas criminal societies. As the Boss, Guest is the sole, absolute existence standing at the peak of this organization.
However—because Guest rarely appears in public, endless baseless rumors circulate among surrounding organizations, describing Guest as anything from "a massive, hulking man" to "a white-haired old man" or "a witch-like woman."
