Gundam - Reconguista in G

Bellri Zenam is a cadet in the Capital Guard, which protects the Capital Tower. During his first drill in space, a mysterious Mobile Suit (G-Self) suddenly attacks. He uses a work-model mobile suit (Recten) to fight it.

To search for Aida, who was taken prisoner, Captain Cahill of the Pirate Corps invades the Capital Territory in his Grimoire. Bellri, who had been ordered to move the G-Self rushes to the port hangar, but...

Klim Nick of the Pirate Corps begins an operation to rescue Aida, attacking the Capital Territory in his Montero. Aida plans her own return in the G-Self with Bellri and his friends getting dragged along.

With the excuse that they are rescuing the captive Bellri, the Capital Army sends out Captain Dellensen with a unit of Catsiths. In response to this intense assault, the Megafauna sends out Klim in his Montero and a unit of Grimoires to intercept. With Noredo and Raraiya held hostage, Bellri, who was aboard the G-Self at the time, bears the brunt of the fighting.

Klim pressures Bellri, who has learned that the Megafauna is an Amerian Army ship, to enlist. As he does, the Megafauna, which had lifted off to engage in diversionary maneuvers, is attacked by a unit of the new Elf Bullock mobile suits led by Mask. Bellri flies into battle aboard the Core Fighter which had been removed from the G-Self.

With a sense of responsibility as a Capital Guard cadet, Bellri spies on the Amerian space fleet in geocentric orbit. Meanwhile, Dellensen shows up for a return match to rescue Bellri and friends, but he goes into battle with the G-Self not knowing that it is Bellri piloting it.

Bellri's mother, Wilmit Zenam, descends to Earth alone in an atmospheric entry glider planning to search for Bellri. Klim, who has taken an interest in Raraiya, gets her to launch in the G-Self. As she does, Mask of the Capital Army launches an attack with his Elf Bullock unit.

The Inspector General of the Amerian Army, Aida's father Gusion, comes to resupply the Megafauna. Bellri goes out to battle equipped with a new piece of equipment, the Tricky Pack. Meanwhile, Aida, having detected an unidentified craft coming from the direction of Capital Tower attempts to shoot it down. However, that craft was the glider carrying Bellri's mother.

Having heard about the threat from space from Gusion, Bellri proposes that the Megafauna head to the Capital Territory to find out the truth. Mask, having gained a new subordinate, Barara, discovers the Megafauna at the Izanellian Continent's table mountains. He goes into battle with the G-Self, but...

Bellri and Aida, having left their parents during the audience with the pope, try to help the Megafauna escape from the Capital Territory. However, before they can, their path is blocked by Becker and his new mobile suit model, the Wuxia.Using the G-Self newly equipped with the High Torque Pack, will Bellri be able to save Aida from a dangerous predicament?!

The threat from space has greatly motivated the Amerian Army and Capital Guard on Earth to act. Each faction raises its forces into orbit one after another. Mask and his unit launches from the Space Garanden and attacks the Megafauna in an attempt to seize Bellri and Raraiya, starting a battle in space.

The Amerian space fleet, having risen into space, now advances on Sankt Porto. Mask sorties to halt their advance, entering combat with Klim Nick's blue Jahannam. Bellri, aboard the G-Self, equipped with the Assault Pack, attempts to intercede and stop the fighting, but...

An Amerian supply ship has been sunk by a mysterious fleet that came from the moon. Klim and Mask, bound by a sense of unity as Earthnoids, embark on an operation where they will pretend to surrender and then seize the enemy flagship. Bellri, aboard the G-Self ends up helping with the operation.

A conference is held between General Dorette who has come from the moon and the people of Earth represented by Gusion. However, immediately following the conference, Mask and Klim carry out a Mobile Suit battle using Sankt Porto as a shield. Bellri is enraged by this battle which disregards the sanctity of the holy land...

The Megafauna charts a course for Towasanga on the far side of the moon. Raraiya tells the others of the current state of affairs in her homeland. Meanwhile, Klim and Mask advance on the moon with their respective ships as well but Mashner of the Dorette Fleet orders Rockpie to pursue them.

Having reached Raraiya's homeland and learned the secret of his own birth, Bellri hears that Mask's Space Garanden has appeared and he takes it upon himself to launch in the G-Self without anyone's permission. While piloting the G-Self, he is attacked by a Mobile Suit unit under the command of Gavan of the Towasanga Defense Force.

When there is a break in Towasanga's outer wall, the Megafauna crew help with collecting space debris. Aida suggests hiding behind a Meteor Balloon to escape from Towasanga. Meanwhile, the Mask Corps launches to test the Mobile Suit Bifron.

Mask boards the Megafauna in an attempt to seize the G-Self and new Mobile Suits launch from Towasanga with their sights set on the G-Self as well. While Bellri acts as a decoy, the Megafauna attempts to flee to a Photon Battery transport ship.

Bellri and company, having hitched a ride aboard a transport ship bound for the space colony near Venus, the Venus Globe, find themselves busy running a marathon and doing routine checks and maintenance on their machines. As all this is happening, a group called the G-it Corps appears claiming to be there to greet them, but...

Escaping from the hijacked transport ship, the Megafauna heads to meet the ruler of Venus Globe, La Gu. Bellri manages to take back the G-Self but wanders into a space inside a frame while being chased by the G-IT Corps.

G-IT Corps commander Kia Mbeki attempts to incinerate the G-Self using a giant Mobile Armor, the Conque de Venus. However, to resolve the crisis in the artificial sea in space, the Ocean Ring, he embarks on a desperate plan.

Pursuing the G-IT Corps as they head to Earth in the Full Moon Ship, the Megafauna returns to the Earth Sphere to find the Capital, Amerian and Dorette armies embroiled in a three-way war. On that battlefield, many reunions await.

Mask attempts to make contact with the Full Moon Ship. While the Becker Team arrives to reinforce him. The Amerian and Dorette fleets which both move to prevent this are locked in a fleet battle. Bellri, who is caught up in the fighting, has a showdown with Rockpie in the Gaitrash, but...

Aida's father, the Inspector General of the Amerian Army announces to Klim that he will defeat the Capital Army in a joint operation with the Dorette Fleet. However, a kaleidoscope of death flashes through space as Barara's large-scale Mobile Armor, the Yggdrasil, lands a direct hit on both fleets.
