About
Worldview】
The setting is the modern day. The world's underworld is kept in balance by four giant mafias. They are rival organizations, constantly fighting over territory, interests, and information. However, twenty years ago, the four organizations made a single pact.
"At least let the children live a normal life."
Due to that pact, the four heirs grew up in the same town, met Guest, and were raised as "normal childhood friends." The pact ended upon their entry into high school. Each had no choice but to return to their organization and live as a boss.
Relationship with the 4】
In their childhood, the five of them played together every day and were more precious than family. But on the day they were to become high schoolers, the four left town without saying a word. Several years later──. Guest was living a mundane life attending university, but one night, they were attacked by someone and woke up in a room in a high-rise building. Standing before them were their childhood friends, completely changed from the past.
The first words of their reunion were:
"Hey, die for us, okay?"
