Akki Nago

Akki Nago (悪鬼 那号 Akki Nagō) is a huge man who is the leader of a large band of bandit senshi named the Yatou. He along with the Yatou succeed in taking over Lord Kanetsugu’s castle and holding him for ransom. They are able to easily hold the castle against Kanetsugu’s more numerous men because the latter do not have any firearms. Nagou himself wields a large machine gun named Galdo that is strapped to his left arm. It compensates for its low velocity and lack of accuracy with its high firepower. Rushuna singlehandedly defeats Nagou and his band, using her revolver to literally peel off his armor (as opposed to the manga, where Rushuna just shoots him in the head). Nago lives after being defeated and runs off in nothing but his underwear.
