Ryuumon

Appears to be a criminal Chinese based group ruling most of Tokyo Kingdom City back in Taimanin Asagi 2. The name translating roughly to "Dragon Gate", they collect protection money, are connected to drug and slave trade, as well as weapon manufacturing.

History
Originally created from a company called "Ryuumon Capital" that bought most parts of the man-made island, financed by the Chinese Union.

They became a mafia controlling most of Tokyo Kingdom City, keeping other groups like Nomad outside with a private armed militia.

However, the orginization is far more dangerous as they were able to kill three Taimanin in the events of Taimanin Asagi 2, having soldier assassin units and ties to demons.

Owning underground facilities for bioweapons, one of the bosses of the group was an Oboro (Clone). The group gained knowledge about body modification from Kiryu Sabato that would sell them data, behind Nomads back.

After the death of clone Oboro by Oboro and their failure to turn Asagi into a weapon, they used an Asagi (Clone) as a prostitute to make money. However, even this clone found its end by its original in that case, Igawa Asagi, that was cleaning up lose ends in the group.

The group mostly lost its power after those failures with members forming their own mafia organizations.
