Gundam Reconguista in G

R.C. 1014: A mysterious mobile suit, G-Self, is being pursued by a group of space pirates and the Capital Guard. The suit is captured by the pirates and the pilot of the suit, Raraiya Monday, is captured by the Capital Guard. A week later, a class of Capital Guard Academy cadets are riding a Crown transport module up along the orbital elevator, Capital Tower, to reach space where they can conduct their first live mobile suit training. On the way up their Crown is attacked by space pirates and their mobile suits, one of which is the G-Self. Bellri Zenam, the youngest of the cadets, pilots a maintenance mobile suit to hold off the G-Self and helps capture the pirate suit as well as its pilot, Aida Surgan.

Capital Territory is attacked by a squadron of space pirate mobile suits led by Cahill Saint, who wants to rescue the captured Aida. Bellri and his friend Noredo manage to rescue Aida as the structure she was being held in was damaged during the attack. Tasked with piloting the G-Self to repel the pirate attack, Bellri kills Cahill in an act of self-defense as Aida watches.
