Sumookingu plot
Uncle Sabe is a former underworld doctor. Now he runs a small group of self-judges, whom he gives orders that should lead to a certain honor or restoration of rights, insofar as a certain honor or right applies within the criminal world. Often the group has to take out a criminal, like a gang leader who has not paid out a promised amount. As proof of the execution of the assignment, the group brings back tattoos, which they have skinned from the backs of the murdered people.
