Oniwaban

The Oniwaban (御庭番) are an elite covert special operations group in the service of the Government of Yamatai. Their duties include espionage, sabotage, infiltration, assassination and guerilla warfare. Due to the highly clandestine nature of the group and its activities, little is known about it. Its operatives are rumoured to live monastic lives of training and study, strictly following the ancient Yashimese traditions in secluded compounds.

Weapons and equipment
The Shinobi are rumoured to shun modern weapons and equipment, instead opting for traditional black attire and pre-industrial weaponry.
