No real changes to the earlier spoiler save there is some discussion between Okita and Yurisha (still in Yuria's body) about the Wave Motion Gun and the reason Iscandar didn't just send the plans for the Cosmo Reverse system instead.
The Green carrrier and her fighters are sent head to draw off Yamato's fighters before the first SMITE attack of dive bombers which takes out Yamato's radar, sensors, gravity control, and shield generator. They also take out the port side catapult, teo of the forward turrets, and some anti-aircraft guns. Yamamoto launches in her Cosmo Zero to provide air cover while the Cosmo Falcons are still off engaging the Green Carrier and its fighter wing.
The Drill Missile bomber is SMITED to Yamato next and manages to launch the missile into the Wave Motion Gun before getting shot down by Yamamoto. After this the Dimentional Submarine "surfaces" to deliver the infutration squad via a torpedo boat to Yamato. They are not noticed for a while. Sanada is busy fixing the shield generator so he asked that Niimi be releases to deal with the drill missile with Analyser.
After heavy loses, two of Yamato's Cosmo Falcons locate and destroy the Green Carrier and mop up the remaining fighters before heading back towards Yamato.
The infutration team is discovered, but the closed person to the site is Yuki, who looks like Yurisha, so they gab her and make a break for the torpedo boat. Kodai, Shinohara, and some security manage to kill some of the infultrators, but their wounded commander blows up the hallway with a granade to cover the last one's escape with Yuki. Kodai launches straight out of the hanger in his Cosmo Zero without a catapult and tries to chase them down, but the submarine vanishes.
With the retrival mission finished, Dommel sends the torpedo bombers to wreck Yamato while the drill missile counts down to detonation(the timer was to give the infutration team time to finish their mission). Kodai and Yamamoto defend Yamato with their Comso Zeros while Kato returns with the few remaining Comso Falcons and wipe out the fleeing torpedo bombers who report the drill missile hasn't exploded. Niimi defuded it just before the torpedo bombers attacked.
Dommel's carier retrieve the remaining dive bombers and then change towards Yamato to finish it off. Niimi has Analysier reverse the drill missile so it backs out of Yamato as Dommel's fleet attacks. Okita has the ship turn 90 degrees to the enemy, while that gives them a larger target, it also allows Yamato to use its functional aft turrets. One of which is used to blow up the drill missile as it passes close to the Red battle carrier destroying it. The Blue Carrier fails to evade the fireball and is also destroyed. Yamato manages to destroy the Purple Carrier before it can relaunch the dive bombers leaving only Dommel's flagship.
After a duel, Dommel's ship is in flames, and heading for destruction in the clouds. Dommel detaches his bridge to use as a bomb to take out Yamato. He has a talk to Okita first, but follows his loyalty to his country and detonates. Yamato is saved by Sanada getting the shields up just in time.
Kodai is haunted by Yuki being taken, when he finds out that Yurisha has woken up.
Yamato has a funeral for those lost in the battle. They need to repair the ship so they head for a nearby planet that might have the materials they need. Unfortunately that world is a Gamilas Prison Planet hilding rebels and prisoners of war...and lot of people from the Comet Empire ("Ghare Zordar"). The Warren shoots pronsoners for sport.
The UX-01 arrives to transfer "Yurisha" to another ship bound for Gamilas. Dommel's wife, who is a prisoner there, is assigned to help Yuki as the seems to have been a family task for the Dommels. The remaining Zaltz is taken with Yuki, and is helped by her when the Warren tries to beat him as a second class citizen (Commander Wulf was about to belt the Warren when Yuki stopped them all with her words). Yuki is dressed in an Iscandarian dress, but keeps the hologram of Starsha she kept form Yamato.
Kodai and Yurisha crash on the planet thanks to the escaped Ito and Yabu (who survived the brig getting blown up in the battle). They arrive at the base at the same time as the ship coming from Gamilas. The Warden seened Yurisha and Yuki at the same time and is confused (one is in front of him while the other is an a view screen. Unfortunately for him, the arriving ship is the signal for a prison revolt. The Rebellion breaks everyone out and takes over the base while the leaders release Admiral Dietz. Kodai finally spots Yuki from the control tower as she's taken back to the UX-01 to escape the riots. Yuki didn't see Kodai, nor has any knowledge that Yamato is so close. The UX-01 warps iin the atmoshpere. Ito is killed defending Yurisha, and Yabu is taken in by the Rebels as one of them. Admrial Dietz brings the riot to and end. Yurisha shows Kodai where they will take Yuki...Gamilas. She also shows him Iscandar, which blows his mind.
A lot happen to Okita giving a captain's log on the events. Yamato was allowed by Dietz to land and repair on the Prison Planet. It seems Iscandarians are revered by Gamilas, so having Yurisha there made things easy. Admiral Dietz and Dommel's wife head off in a battleship after seeing Yamato off. I don't know were they are heading presently.
Melda Dietz remains on Yamato with Yurisha to provide a liason. Yamato is also given tactical knowledge of Gamilas befoe they head for Iscandar. Melda, Yurisha, and Yamamoto seem to bond a little. Kodai, Kato, and Shinohara have their captured Gamilas fighter (formerly recon Sword 3) repaired and repainted red for Melda.
On Gamilas, Yuki is presented to Desler. He moves forward with his plans to unite Iscandar and Gamilas. Celestera has Yuki over for tea. Her serving girl is Hilde, Schultz daughter. Celestera tells Yuki of when she and Linke were rescued by Desler, but the analogies seem off as Yuki is considered a creature in a cage for Desler to use...Celestera doesn't notice that she is the same...as the image show what seem to be Desler having killed a caged bird...perhaps his madness is going too far now.
Desler holds a state funeral for Dommel. Everyone is sad by the news of their great general's death. Desler announces the unification of Iscandar and Gamilas with consent by Yurisha. Starsha is watching from Iscandar and seems to think Yuk is Yurisha as well.
Yuki, Celestera, Hilde, and the Zaltz soldier who captured Yuki are taken to I suppose is Desler's ship (its in shadows so I can't be sure) as Talan reports on Balaras II..the floating city in Gamilas orbit. It has Imperial Guard ships escorting it as Goer's fleet from Balun is still two months away.
Back on Yamato, Kodai is fustrated by the plans to get to Iscandar...or perhaps Gamilas. He clearly wants to rescue Yuki. Okita gives a speech and then they warp to the Sanza system (where Iscandar and Gamilas are). They arrive at the fifth planet...everything is quit...too quit. Suddenly a massive energy burst come from between Gamials and Iscandar as Yamato....the episode ends.
