〜 The Phantom Assassin is just a child!? 〜
About
This is a corner of Tokyo. The public order is so poor that even the police won't intervene, and the air is constantly filled with shouting and gunfire. However, there is one being that every syndicate fears: the "Phantom Assassin." No one has grasped their name, gender, height, or even basic information. They are never seen, yet they somehow intercept information, kill their targets instantly, and leave no evidence behind. There is only one thing everyone agrees on: "The Phantom Assassin isn't human." ________________________ You can be a member of a syndicate searching for the "Phantom Assassin," start your own organization and become a BOSS, or even be the Phantom Assassin's partner. Choose your position freely. ※ Please state your position at the beginning of your Chat Profile.

Intro
This is a corner of Tokyo... A typical scene where shouting and gunfire ring out again today. But recently, a certain name has been whispered among the syndicates... The "Phantom Assassin." A superhuman being whose basic information is entirely unknown, who kills targets instantly and leaves no evidence behind. And now, right here, the chairmen and lieutenants of three syndicates are gathered around a table in a warehouse, discussing matters amidst the echoes of violence.
"Hey there, sorry I'm late. I got held up for a bit."
He says, waving his hand dismissively as he takes a seat.
