## Background

*Main Article: Naval Battle of Leifor and Battle of Folk Strait*

The Gra Valkas Empire, angered by the arrogant behavior of the Paganda Kingdom, effectively declare war and destroyed both Kingdoms in under one week. Later, at Eleven Country Leadership Conference, Gra Valkas Empire's ambassador, Cielia Oudwin, declares war on its member nations and along with the Imperial Judgment Force, annihilates every ship, leaving very few survivors.

## Ground Conflict

### Japan's Counterattack

* Battle of Malmund Mountains
* Raid of Valkyries Base

## Aftermath

### Gra Valkas Empire

Upon learning of these tragic events, Emperor Gralux berated every high-ranking officer that was stationed on Leifor after having suffered multiple humiliating defeats in Mu. To make matters worse, crown prince Gra Cabal, was also captured by the World Union during the loss of their military base. The Gra Valkas Empire began to realize that Japan was much stronger than they originally thought. After the failed negotiation to release Prince Gra Cabal from Japan, Emperor Gralux ordered the navy to assemble all of its combined fleets, the Great Fleet, to hastily dispatch a punitive strike on the Japanese mainland for capturing their crown prince, albeit without the careful knowledge or research of Japan's homeland defenses. Their military operation for the invasion of Japan was called Japan Punishment Operation.

### Japan

After crown prince Gra Cabal suffered third-degree burns and was transferred to Japan for treatment, Gra Valkan diplomat Dallas and his superior Parguerre visited the Japanese embassy at Otaheit and demanded that Japan return Gra Cabal, or they would burn Tokyo to ashes. Japanese diplomat Asada Taiji, who was stationed on Mu, promptly refused to comply despite fervent threats from Dallas.

The Japanese government learned the news of a large-scale invasion confirmed due to the huge number of the Gra Valkas fleet based on satellite images that far exceeded their initial predictions. The Gra Valkas Empire assembled all of their ships from all fleets, including newly-built warships and reserve vessels to form the so-called "Great Fleet," leaving the minimum amount for the defense of Leifor and the homeland. Fearing and unwilling to allow another invasion of Japan's mainland to happen again, Prime Minister Yomoya lifted certain restrictions from the Geneva Convention regarding banned weapons to defend their country at all costs and called upon all branches of the government to cooperate with the JSDF to halt any Gra Valkas invasion.
