Meteor City

Meteor City (流星街, Ryūseigai) is a junkyard city inhabited by outcasts. People who live there do not exist in any official records, and the existence of the city itself is known to very few people. Not much is known about the city; much of the information on it is shrouded in mystery. The city is rumored to be at least five hundred years old, and was believed to have been founded by a dictator who wanted to separate the human race. Since then, it has been a dumping ground for other countries. The city is said to have the most diverse ethnic background and its population estimated at eight to ten million people.

Outsider Threat
At some point, Meteor City was to be attacked by an outsider. An elder used his hatsu, Sun and Moon, to turn some residents into human bombs in order to send a message to the assailant.

The Tramp Incident
About 10 years ago, a tramp without papers was arrested for murder. When the local law enforcement tried to look for information about the tramp, they found nothing. It was then that the tramp confessed that he was from Meteor City. The police of the country refused to believe his innocence from the murder, instead forcefully extracting a "confession" that he did commit the crime. During the trial, the lawyer appointed by the court did not do anything and allowed the tramp to be condemned. Three years later, the real murderer (a drug addict) was arrested and his crime was brought out to the public. It was then recognized that the tramp was falsely accused.

Shortly after the information was revealed, a total of 31 people consisting of the police, judges, inspectors, witnesses, jurors and lawyers who took part in the false accusation of the tramp were assassinated. In one of them, a message was found near the corpse's foot, saying: "We reject no one. So take nothing from us." The assassins were a bunch of 31 Meteor City residents that attached a bomb onto their chests, then exploded themselves with their victims, all at the exact same time, in different locations. All because one of their companions was falsely condemned, 31 people sacrificed themselves, and 31 others were killed, in the name of revenge.

Kurta Clan Massacre
Five years prior to the start of the series, the Phantom Troupe approached the Kurta Clan for their valuable Scarlet Eyes, massacred everyone there and left a message of what seems to be Meteor City's motto: "We reject no one, so take nothing from us."
