Kinjo and Ginta Amatsuki enrolled Nagareboshi Academy as a new students in order to keep their eyes on Tsubaki from any dangerous threats. Meanwhile, Gothic has been survived and rebuilt into the cyborg form, but Blackgate and Thrash were have the last chance to fight the RyuseiRangers. Wanting to get revenge on the RyuseiRangers, Gothic captures Tsubaki and the Gladiators were no match with them. So, the RyuseiLunarious duo comes to rescue Tsubaki.


The Amatsuki brothers, Kinjo and Ginta, enrolled Nagareboshi Academy and attended NagareFesta house to be the parts of Committees at the festival. Queen Penelope told them to watch on where Tsubaki is going to do.

Tsubaki greets to the Amatsuki Brothers, who're impressive by her songwriting and asked if they want to join them as the Committees, but Ray said he isn't worthy it. But after watching Kinjo playing on trumpet and Ginta does a photographic sessions, Daisuke declares that their skills are very worthy, allowing to them to attended it.

Meanwhile, Niewial was very upset at Blackgate and Thrash's failure, giving them the last chance to defeat the RyuseiRangers or else they will replaced by the new band. However, it is revealed that Gothic managed to survive his battle with RyuseiOh, has been rebuilt into a cyborg by the most powerful General Nu, and is heading towards Earth, intending to exact revenge on the RyuseiRangers.

As she is still worried about up-and-coming attack, Tsubaki goes out to take some fresh. Just then, the siblings confronted by the newer Gothic, who is determined to get revenge on them, kidnapping and placing her in the Pod of Hell to lure them and defeat them.

The RyuseiRangers were back off by the elite foot-soldiers HellCore, who are stronger than DroneCore and Daisuke is no match with them, despite knowing the odds are against them, especially since General Nu is far too powerful than Gothic. However, as soon as Gothic, Blackgate, Thrash, and their army of HellCore prepares to defeat them, they are met by Amatsuki Brothers, who says that they has comes to defeats them.

Using MeteorSwitchers given to them by the Queen, the Amatsukis transforms into their corresponding Gladiators: RyuseiSol and RyuseiLuna, known as the RyuseiLunarious, and easily takes out HellCore soldiers. Kinjo and Ginta breaks into the vine tower to rescue Tsubaki, who rejoins the RyuseiRangers to let them fight against Gothic. The duo surprises Gothic by telling him that they're RyuseiRangers' side, terrorizes him in the process. Gothic attempts to destroy the RyuseiLunarious, but is unsuccessful. The duo urges Gothic to use his full power, but Gothic is hesitant to do so (since he planned to save his full power for fighting the RyuseiRangers), though he eventually decides to unleash a Gigas Inferno, his most powerful attack on them. The duo is able to hold back Gothic's attack with Moonshine Illusion. Gothic manages to avoid Ginta's detonation of the Moonbeam Shoot. Soon afterward, Kinjo slices Gothic's arm with the Sunrise Rapier, before they blasting him away with finishing attack, Shining Screw Burst.

Angry for destroying Gothic, Blackgate and Thrash summons DestroyerKing, their personal robot, to defuse RyuseiOh's combination and the MetaStar Robots were lost their forms. Despite unable to bring them back together because Eros cannot holding back, the new top designers, Soare and Fengari, just arrives to saves them and combined into the fourth mecha and their ally: GingaShin. Blackgate and Thrash tries to defeat GingaShin by themselves, but GingaShin easily destroys DestroyerKing and the duo falls to the ground, losing their match for the last time. After they quit from DeviPunk army, General Nu attacks Daisuke, declaring that he's his nemesis, who his brother Masaru defeated DeviPunk army 10 years ago before retreats.
