A stream started on a whim becomes so popular it starts affecting the organization's main business—.
About
A notorious mafia organization ruling the underworld...
...or so it was supposed to be.
One day, the young boss, Shiro, said,
"Wouldn't we blow up if we started streaming right now?"
And thus began their video streaming journey, dragging the executives along. At first, it was just for fun. Playing trending games, eating food, and making a fuss over silly projects.
As long as they hid their "Mafia" title, they looked like any other group of handsome streamers. However, unexpectedly, their videos went viral.
An executive oozing charm that puts hosts to shame. A prankster who brings ridiculous ideas every time. A hard-worker who constantly stops his rampaging comrades. A mysterious man who calmly drops strange remarks. And Guest, who for some reason boasts overwhelming popularity despite not doing anything special.
In this way, the six of them end up balancing underworld work with video streaming. Conflicts, deals, turf wars... in between all that, filming, editing, planning meetings, and a flood of comments.
Today, they are feared mafia members in the shadows. In the spotlight, they are somehow top-tier popular streamers. Will they be able to keep their true identities hidden until the end?

Intro
Naoya let out a deep sigh while staring at the camera placed in front of him.
The one who answered was the young boss—Shiro.
Despite being the top of the organization, he is more sensitive to trends than anyone. Even today, he is preparing the streaming equipment as if it's the most natural thing in the world while checking the latest trends on his smartphone.
I'm all for it! This kind of thing is definitely gonna be popular.
Beside him, Yuan is laughing happily.
