Watch Mobile Suit Gundam: Iron-Blooded Orphans

As the fierce battle between Tekkadan and Gjallarhorn continues, a new threat appears. To protect Kudelia and the others, Mikazuki must confront it alone.

Orga and the other Tekkadan members have finally reached Edmonton, but they are attacked by Gjallarhorn, which seeks to prevent Makanai from making it to the parliamentary session.

As Tekkadan heads for Edmonton, it finds Carta blocking the way, seeking a showdown. However, Mikazuki and the others won't let their progress be halted, and they press on ahead.

Though Tekkadan is exhausted by its repeated battles with Gjallarhorn, its members are still determined to get to Edmonton, and they hasten toward their goal.

During preparations to depart for Edmonton, Tekkadan finds itself under attack by Gjallarhorn. Setting a trap for their relentless pursuers, Orga makes a counterattack.

Tekkadan has finally made it to Earth, successfully introducing Kudelia to Arbrau's representative, Makanai Togonosuke. However, they will have to accompany Makanai to a parliamentary general session taking place in Edmonton.

With its path blocked by Gjallarhorn's fleet, Tekkadan attempts to descend to Earth in response to Kudelia's request. The battle against Gjallarhorn soon becomes very fierce.

Tekkadan's members attempt to leave the colonies behind and descend to Earth at last, but they miss their chance due to one last item of business in the colonies. They are contacted by someone who claims to be their supporter.

Kudelia and Tekkadan witness Gjallarhorn's brutal suppression of the workers. Seeing the true situation of the colonies, Kudelia makes a fateful decision.

The colony workers have launched a protest movement against the company that employs them. As they grow more radical, the situation finally develops to the point of a Gjallarhorn intervention.

Just as on Mars, the colonies suffer great disparities with Earth, and a protest movement has begun among the increasingly dissatisfied workers. As it gradually intensifies, Tekkadan is caught up in various schemes.

After overcoming many difficulties, Tekkadan is finally about to reach Earth. Its members head for the Dort colony cluster, to deliver an item that Teiwaz asked them to transport when they were aboard the Saisei.

The battle with Brewers has cost many lives on both sides. The survivors hold a funeral service to pray for the rebirth of their fallen comrades.

Mikazuki and Orga learn that Akihiro's long-lost younger brother is one of the Brewers mobile suit pilots. Tekkadan challenges Brewers in order to get back Akihiro's brother.

While on patrol, Akihiro and Takaki encounter unknown enemies and engage them in battle. The attackers turn out to be Brewers, a pirate group that operates between Mars and Earth.

Tekkadan and Turbines go on ahead to Earth, leaving Mikazuki and Yukinojo on the Saisei to complete final adjustments to the Barbatos. But the events aboard the Saisei have greatly affected their respective states of mind.

Accompanied by Naze, Tekkadan visits the Saisei, the stronghold of Teiwaz, in order to meet with Teiwaz's representative McMurdo Barriston. Here, Orga receives a surprising proposal from Naze.

Having demonstrated Tekkadan's strength and legitimacy to Naze, the leader of Turbines, Orga and the others renew their negotiations with Teiwaz. Meanwhile Atra visits Turbines's warship, bringing the frustrated Kudelia with her.

Tekkadan has made contact with Turbines, which runs Teiwaz's transport division. But they find themselves clashing with Turbines over their group's origins and property.

The members of Tekkadan need a guide in order to reach Earth despite Gjallarhorn's surveillance. To gain a powerful backer, they attempt to negotiate with Teiwaz, which is based in the Jupiter Sphere.

Kudelia and Tekkadan finally leave Mars behind them and head for Earth. With a ship waiting for them, they attempt to travel by shuttle to a low-orbital station, but are attacked by Coral's Gjallarhorn forces.

Kudelia is distressed that so many boys have lost their lives because of her. Mikazuki takes her to the farm run by Biscuit's grandmother, where an unexpected encounter awaits.

The adults of CGS flee in the face of Gjallarhorn's attack, using Mikazuki and the other children as decoys. Gathering the children who have been left behind, Orga decides to fight back against Gjallarhorn, and puts a certain plan into motion.

Mikazuki belongs to the private security company CGS, at the Martian city of Chryse, which has been hired to escort a girl named Kudelia to Earth. But just as preparations for departure are underway, Gjallarhorn attacks CGS in an attempt on Kudelia's life
