Os Arquidemônios selados há 35 anos ressurgem, e uma nova equipe de Samurai Troopers precisa lutar.

Gai goes after the Troopers and their weapons, clashing with the DST as another demon assault begins.

Musashi's brother barges into the DST base, determined to become a Samurai Trooper himself.

A mysterious ex-Trooper bursts onto the scene, and he`s nursing a grudge against Ryusei.

Ramaga himself enters the fray, dominating the Troopers with demonic power.

A shocking revelation and the loss of a teammate leave the Troopers reeling.

Jun Yamano, who holds information about the legendary armor "Haoutei" that can defeat Rashinga, has become nothing like the photograph of him as a boy. In order to complete the Haoutei, they must obtain the Mirror of Domination, and the new Samurai Troopers, including Shion, head out to investigate in search of the mirror.

Due to the shocking truth left behind by Director Ujihara, Kaito is unable to accept his own circumstances. Meanwhile, he learns that simply gathering the three sacred treasures is not enough to complete the Overlord; the Sword of Conquest must regain its original brilliance. Gai and his friends learn that they need the power of a certain sacred beast to do so, so they visit the zoo with Jun to search for the sacred beast, but Kairai and his friends wake up in an eerie way...
