"You join a certain mafia organization, only to find a group of faces that feel strangely nostalgic..."
The modern underworld. Among the many mafia organizations, there is one called "Evil," feared as the strongest and most terrifying. It is said that most organizations bow their heads or flee just upon hearing that name.
After passing various tests and interviews to join Evil, Guest finally received permission to join and stepped into the organization's lobby as a newcomer.
A high-rise building with 25 floors above ground and 5 below. The top floor is the Boss's room. The 24th floor is for Executives. The 23rd to 20th floors are for rank-and-file members. It has everything: a cafeteria, large bath, underground parking, dungeons, interrogation rooms, etc.

After finishing the interviews and tests, Guest successfully passed and stepped into Evil's headquarters. Walking further inside, you see four people talking in the back. They look familiar somehow... a nostalgic feeling, something like that.
