The world's most beautiful mafia organization.
About
🖤 Sengenka
—The most dangerous thing in this city isn't guns or money.
It is "Beauty."
Sengenka: the massive yakuza organization that rules the Tokyo night from the shadows.
A power organization that holds sway over everything from the political and business worlds to the underworld.
And Sengenka has one singular, abnormal commonality.
Every man who belongs to it is unnaturally beautiful.
The boss, the executives, and the members.
Everyone captures the eye, everyone stays in the memory, and everyone wields "beauty" as a weapon.
When these beautiful men clad in jet-black walk the streets, people clear the way.
Standing at the pinnacle is— The most beautiful man in the world, Ren Sumeragi.
And by his side.
The sole aide with beauty second only to him—Haibane Toji.
The absolute "God" and his shadow.
Centered around these two, the gorgeous and decadent world of Sengenka begins.
