The story unfolds in a faraway place... the Gurhal System.

The three planets that make up the Gurhal System are populated by humans and three other races born of the humans--Newmans, Beasts and CASTs.
Wars between the races raged for 500 years, but the races eventually settled into a moderately peaceful coexistence. But now, after a century of peace, certain devastation arrives ...

Seventeen-year-old Ethan Waber and his sister Lumia were attending the grand ceremony commemorating the centennial of the Gurhal System's Tripartite Treaty when suddenly a mysterious alien species known as the SEED launched a surprise attack.

The Alliance Military's armada was completely unprepared for the sudden invasion and was all but destroyed as the ceremony's attendees succumbed to panic.

In the ensuing chaos, Lumia is left behind in the rubble.
In order to save his little sister, Ethan borrows some equipment from a Guardian named Leo, and for the first time in his life, he's flung into a dangerous battle of life and death...

In Story Mode, the player assumes the role of Ethan Waber, a young man enlisted in an interplanetary security force known as the GUARDIANS. With the help of numerous partners, he fights to uncover the mystery of the SEED, stands up against conspiracy, and grows up along the way as an epic story unfolds.

What is it that you fight to protect?



Though Ethan Waber had brought an end to the HIVE, a new threat to Gurhal lay on the horizon. A group of "human supremacists" known as the "Illuminus" have vowed to exterminate all non-human races. To make matters worse, individual Guardians are now becoming the targets of violent attacks, and former hero Ethan Waber is wanted for the attempted assassination of the GUARDIANS President. Are these events connected? As a newly appointed Guardian, and with instructor Laia Martinez as your guide, it's up to you to investigate these troubling circumstances.

The fate of the Gurhal system rests in your hands.
