SD Gundam Sangokuden Brave Battle Warriors

The story begins in Yuushu where a couple of Yellow Scarves troops are harassing some villagers. Ryuubi Gundam steps in and easily chases off the two. He is thanked, and soon, Kousonsan Ez-8 arrives and comments on how Ryuubi should think before he acts. Kousonsan also informs Ryuubi of their Master, Roshoku GM Cannon, who will soon head out to subjugate the Yellow Scarves forces. Before he left, Roshoku presents the Ryuuteiken to Ryuubi. Ryuubi comments on how rusted it is, but Roshoku comments on how Ryuubi is still rooted to the village and unable to see past the rust, and that he should use the Dragon's Eye. After Roshoku left, Ryuubi climbs up a pagoda, and looks beyond the horizon, finally understanding Roshoku's words. However he spots a battle in the distance, and fears Roshoku's safety.

Ryuubi is travelling through a forest that lies south to his village, where he soon hears a battle. He soon sees two warriors engaging each other, one with red armour, and another with green armour. Ryuubi draws the Ryuuteiken to stop the battle, but it didn't awaken like when he was fighting against Bagengi. He decides to personally stop the two from fighting, but trips in the process. When he regains consciousness, the two warriors introduced themselves: The red one is called Chouhi Gundam, while the green one is Kan-u Gundam, though Chouhi prefers to call him Demon Beard. When asked why he wanted to stop the fight, Ryuubi commented on the Ryuuteiken, and deduced the two aren't evil. Chouhi then takes Ryuubi on a tour around his village, stating that he has been protecting it against the Yellow Scarves. However, word soon arrives that a small army of Yellow Scarves has appeared just outside the village.

Ryuubi, Chouhi and Kan-u arrives at Eisen, but they spot other armies have already surrounded the Yellow Scarves' stronghold. These armies are part of the Imperial Subjugation Army, led by the general Shushun Zaku Cannon. Inside the stronghold, Chouryou, along with Choubou Bolinoak Samaan, are panicking over the sheer force of the army outside. However, Choukaku Palace Athene is not afraid, and has a plan to counter them. The East Wing of the army is led by Sousou Gundam, and decides to attack without Zhu Jun's order. The West Wing is led by Sonken Zephyranthes, and he too decides to attack. The two wing armies attack, and Chouhi wants to join in the battle. However Ryuubi stops him, saying that something is amiss. Back at the Main camp, Shushun is enraged at the unannounced attack from the wing armies. The two wing armies soon realize that the Yellow Scarves defense is spread too wide, and the invasion seems too easy. The Chou brothers have escaped.

At the capital Rakuyou, Ryofu Tallgeese has infiltrated the palace of Reitei Gundam, the Emperor of Mirisha. Leaving dead bodies in his wake, Ryofu proceeds to kill Reitei. Toutaku Zaku praised Ryofu for his efforts, and proceeds to take the Gyokuji, proclaiming himself the new ruler of Mirisha. Outside the palace, Ryofu encounters Chou-sen Qubeley, who calls him Housen. Chou-sen is concerned about Ryofu letting Toutaku seize the Gyokuji, but Ryofu replies his only goal in life is to seek out strong warriors to quench his battle-hungry soul. Over at Sousou's camp just outside Rakuyou, Sousou watches on as Kakouton Giros is enraged at Toutaku's plot, while Kakouen Daras feels helpless about the situation. However, they are soon greeted by a wandering strategist, Shiba-i Sazabi. He brings a treasure, the Shichiseiken, and believes that this can whet Toutaku's appetite, and be allowed an audience with him.

The Anti-Toutaku Alliance is formed, and Ryuubi, Chouhi and Kan-u make their way to the Alliance campsite. Once there, they meet up with Kousonsan, who joins his father's army in the Alliance. Ryuubi introduces Chouhi and Kan-u to Kousonsan, who makes a comment that the three combined has the strength of one hundred men. Sousou and Sonken Zephyranthes also welcomes the sworn brothers' arrival. However Enjyutsu Zssa, the second-in-command of the Alliance, is not pleased. A small squabble between Chouhi and Enjyutsu starts, until Enshou Bawoo, the commander of the Alliance steps in. Enshou comments on how the En family is privileged to lead the Alliance, and that he doesn't not need backwater peasants in his Alliance. He is soon interrupted by word that Toutaku forces has attacked the campsite.

The episode begins with Sonshoukou Gerbera rushing towards the Anti-Toutaku campsite. At the campsite, Sonken Gundam is mopping about the coming battle. Both Sonsaku Physalis Gundam and Kougai Gouf are dismalled at Sonken, trying to get him to man up. Sonken Zephyranthes steps in, stating that they will take the initiative to break through Koroukan. At this point, Sonshoukou arrives, much to the dismay of Sonken Zephyranthes, Sonken, Sonsaku and Kougai. She wants to be accomplished in battle as well, and begins to show her finishing technique. Though she was initially skillful at it, it soon turned disastrous.

With the defeat of Kayuu, Ryofu jumps out from the Koroukan, preventing the Son army from advancing any further. He only wants to duel Sousou, who promptly steps forward. However, Ryofu's strategist, Chinkyuu Mercurius steps in and uses his strategem of fire, a stratagem where he has doused the land with oil, to burn the advancing force. But Shiba-i has anticipated this attack, and reversed it with his own stratagem, burning Chinkyuu with his own flame. Soon, Koushun Vayeate and Chouryou Gelgoog step in to take down Sousou. However, Kakouton and Kakouen step in to protect Sousou. Ryofu grows tired, and attacks, injuring Kakouton's left eye. Sousou orders Kakouton to step down.

Back at the capital Rakuyou, Toutaku comments with Ryofu at the Koroukan, no one will pass. Riju Shokew, Toutaku's strategist comments that with the gathering of various heroes in the Alliance, Ryofu might be overpowered eventually. This leads to Toutaku commenting that it's Riju's job to make sure Ryofu doesn't fall. At the Koroukan, Ryofu stands guard as Chou-sen comments on Toutaku again. Ryofu gives the same reply, saying that all he doesn't care about Toutaku, all he cares about are battles. Over at the Alliance campsite, Kousonsen is arguing with Enshou about the next plan of action. That is until Ryuubu steps in and requests that he, Chouhi and Kan-u will take down Ryofu.

A mysterious traveller, Koumei Re-GZ, has arrived at the capital Rakuyou. He is in search of the source of darkness that has shrouded the whole of Mirisha, and sends out his Bakuoki. At the imperial palace, Jyokou Serpent is informing Toutaku on Ryofu's defeat. Ryofu steps in, accepting his failure at the Koroukan. Toutaku is furious, until Riju steps in with a new plan. They are to retreat to the Biujiyou at Chouan, and to set Rakuyou ablaze for the Alliance. Jyokou is strongly against this plan, thinking about the citizens, but Toutaku cares not of the citizens. Chou-sen comments on how both Toutaku and Riju seem to be possessed.

As the Son army witnesses the capital in flames, Shuuyu Hyakushiki spots Toutaku escaping in his chariot. Sonken Zephyranthes orders his army to chase after Toutaku, and to regain the Gyokuji. As the troops leave, Shuuyu requests Enjyutsu and his troops for rear support, and leaves. However, Enjyutsu grows paranoid, thinking that if Sonken Zephyranthes defeats Toutaku, the Gyokuji will be in his hands, and become ruler of Mirisha. Enjyutsu doesn't want that to happen, and orders his general, Kirei Hamma Hamma, to attack the Son army. As Sonken Zephyranthes catches up with Toutaku, he orders Ryofu to take care of the Tiger of Koutou, to redeem his honour.

Back at the Alliance campsite, Kousonsan and the sworn brothers hear the news of Sonken Zephyranthes' death, and how the Son army, now under Sonsaku, is still giving chase after Toutaku. The four decide to join up with the Son army to back them up. At the main gate to Rakuyou, the four are stopped by Chou-un Gundam, an officer under Enshou. Enshou has barred anyone from supporting the Son army's chase. Angered by this, Ryuubi draws his sword, to which Chou-un draws his spear. They both discuss how a soldier should follow a commander's orders and how one should always support their allies. Kousonsan steps in and agrees with Ryuubi's point of supporting one's allies. At this point, Chou-un succumbs, but he will personally escort them.

The Anti-Toutaku Alliance, minus Enshou and Enjyutsu, makes their way towards the Biujiyou, where Toutaku currently resides. Kousonsan decides to take a rest before crossing a river, and announces that they will begin their attack at dawn the next day, where they will rendezvous with Sousou's and Sonsaku's armies. Ryuubi decides to take this chance to fish for food. At the riverside, Ryuubi meets Koumei, and finds out that the fish are not biting. Koumei comments that perhaps a large fish has eaten the smaller fish, and Ryuubi states that if he catches that fish, the river will be at peace again. Koumei asks what if about large fish invades, and Ryuubi states he will catch that too. Koumei laughs. When Chouhi searches for Ryuubi, Koumei mysteriously disappears. Night falls, and the three factions prepare for the coming final battle, each having a common goal to defeat Toutaku, which results in the Gyokuji glowing brightly with a pure light.

Ryofu is engaged in battle with Sousou and Sonsaku, just before the arrows rained down. As they did, many of the Infantry GMs and Zakus are hit. Sonken rushes in to protect Sonshoukou, while the other generals watched in disbelief. Kan-u comments on how tyrannical Toutaku is to injure his own troops, just as Ryofu is hit. The arrow volley continues and more are killed. When the volley stops, the battlefield is filled with corpses from both sides. Ryofu still stands, and pulls out the arrows on his back, demanding to finish the battle with the heroes.
