Clan Najimu is a former lesser samurai clan during the Seigun period (1154-3112 RH) that evolved into an underground organized crime syndicate operating in Tatsu, Tekkan during the Industrial Era (2980 RH).
The clan is currently owned by the mutant koicodile Gakugyo; who ripped the previous boss's head off with his jaw after he sold him for his luxury scales. After Gakugyo took the position, the clan fell into many territory disputes with lesser outfits attempting to compete or overthrow the koicodile.
