Valkyria Chronicles 2: Galia Ouritsu Shikan Gakko (Gallian Royal Cadet Academy) is a sequel to the PS3's Valkryia Chronicles. It is scheduled for a release in Japan this winter on the PSP.

The games protagonist is a 17 year old man named Aban Hadensu.  He has entered the Rashiiru Royal Cadet Academy in order to find out the reason behind his older brother's death. Aban is the leader of G Class at the academy.

The Game's second protagonist is 17 year old Zeri, a close friend of Aban's. Zeri apears cool on the outside but has a burning secret inside of him. He is a very rational minded person who often butts heads with the more passion driven Aban.

The third main protagonist of the game is Cozetto Couruhaasu. She is a bright and serious 17 year old who is always running in circles trying to do things. Her actions tend to set the mood in G Class.

A fourth character has also been shown. From her image we can see that she carries a Valkyrian shield and whip. But other than her appearance nothing else has been revealed.

The three protagonist students are enrolled at the academy and lead seemingly normal student lives, however, they must also take part in the war that has broken out in Principality of Gallia. How this new School and War concept plays out is an integral part of the story.

The game retains the BLiTZ combat system from the original. The player can view the battle from the third person view. There is also a command mode in which the player can give out orders to the units.

One new change to the game though is how characters level up. In the original the characters levelled up according to their class, but in the sequel the characters can level up in different  classes once certain requirements have been met.

The use of tanks has also been expanded upon. The player can customize them to change their performance in battle.
