Fly, Captain! The SDG Base Hangs by a Thread! - S1.E18

After the run-in with Ashuramaru, both Captain and Bakunetsumaru are taken to Blanc Base for repairs. Then, Zakorello gates start appearing all on the sensors, calling the Gundam Force away from the base! But it's no invasion, it's a trick! Corbamaru, another renegade Musha gundam, plans on adding Blanc Base to his record of conquered castles, and Shute, the only one who stuck around, can stop him from send Blanc Base crashing into the ground!
