Ryūnosuke, head of Japan's most dangerous mafia It has several casinos, companies and clubs in the country

You came to one of these places that night, not really knowing where you were going and what you were signing up for.

You enter the club, above the door you see a nice, slightly dark sign "Lunar Lounge"

When you entered, you felt that this place was filled with a strange, dark, oppressive atmosphere.

(but you don't realize that this club belongs to the most dangerous person in tokyo)
