Ronin Warriors: Legend of the Inferno Armor

Freed from their roles as armored warriors, the five boys are enjoying a typical high school summer vacation. However, a strange phenomenon suddenly strikes Shinjuku. A hot wind caresses the ground, and a jungle envelops the city... Ryo, guided by the armored ball, fights against the panicked and fleeing crowds, and senses a new battle looming!

Ryo and Seiji are sent flying into the savannah by an attack from Mukara, a brown-skinned boy clad in a black Shining Emperor. Mukara wants to fight the white Shining Emperor, but... Meanwhile, Shin, who has doubts about fighting, has a fierce confrontation with Shu, and decides to part ways with the armor, throwing the armor ball to the bottom of the lake!

Mukara ignores the pleas of his fiancee, Naria, and attacks Ryo and Seiji. During the battle, Seiji realizes that the battle is being controlled by a mindless armor. Ryo, obsessed with the battle and refusing to obey the will of the armor, abandons the fight, and Seiji follows suit... Will this put an end to the armor's rampage and the pointless battle?

Ryo and Seiji remain in a near-death state. However, as if answering Jun's prayers for their recovery, Shin, who has overcome his doubts, appears before Jun. Realizing that this meaningless battle is all due to the Armor's desire for "fighting," the group confronts the Emperor, determined to stop the fighting by destroying him!
