Yamato is still heavily damaged from the battle with Dommel. Admiral Okita passes out again from the strain and is ordered into bed to rest. Sanada is in command. They arrive at Beemera with Niimi handing Shima a note. It is time.
Kodai, Yuria, Analyser, Harata, go down to the planet. Analyser gets a big walking mech to help them thought the dense forest. At first Yuria seems normal, if sleepy, but after they get panetside, she loses her hair things and starts talking weird (and acting weird). They get chased by a local animal...Yuria being carried by Analyser....she's laughing the entire time. It eventually sees something and wonder off. They find what seems to be another Iscandarian ship.
On Yamato, Niimi has a talk with Sanada to attempt to get him to abandon the Yamato Plan in favor of resettling humanity to Beemera. He refuses. Ito comes in and Sanada asks him to put her in the brig. At which point Ito aims his gun at Sanada. Around the ship, security guards start rounding up key personel. Taking the Pilots captive (save Yamamato who I think was in the bathroom), the captain hostage, and commondeer the bridge with Shiima's help. Shima declare the Yamato Plan is cancelled. Yabu and the younger engineering staff hold their seniors in the Engine Room.
Ito declares Yuki to be an alien, using an alean recording device she had earlier as proof. It has a recorded message from Starsha to her little sister on it.
Meanwhile on the planet, Kodai's group discover the Bee People are dead for something like 400 years. Inside the spaceship is another Wave Motion Core. This one with information about some sort of Warp Gate System. They decide to take this back to Yamato, but Yamato doesn't respond to their signals.
On Yamato, Hoshina (the young security guard) comes to get the Doctor. They head up to check on the Captain. In the brig, Yuki, Nambu, Ota, and Aihara are confined under guard, while Yamamoto arrived from the vent system to free them. They head to the hanger bay to contact Kodai. making contact they open the hanger for him.
On the Bridge, Ito is hatching a plan that sounds like he's going to make it seem like Sanada and the Captain died so their won't be questions when they get home. Orders Shima to head out. Shima wants to wait for Kodai, but follows orders. Until the hanger doors start to open. At which point he follows procedures to let them on. Ito orders him to fly while Niimi tries to countermand, which gets Ito angry and raising his voice. Shima stops the ship. to draws his gun, and sets it to kill Shima. Niimi knocks him away, by manges to injure herself in the proses. She confronts Ito, who turns to shoot her. Shima draws, but it doesn't seem fast enough.
Until Ito's gun is shot from is hand. By Hoshino. The Captai them comes down to the bridge and yell at them all. Kodai's party lands and he is enthusiastically hugged by Yuki. He's sort of stunned by this since he doesn't know what is going on.
Hoshino is a plant by Commander Todo into the Izumo Plan people...just in case. Shima was brought into the plan by Hoshino to see what they did. Kodai delivers the route to a Gate in the Beemera system that will get them to Balun.
