In the game's world, the Kingdom of Fantasinia has for generations been ruled by an imperial family in whose veins flows the blood of the gods. Governed by wise kings, the country flourished and enjoyed decades of peace. However, during the reign of the 31st king Ordeen Fantasinia's decline began as it faced an invasion by the newly established Bronica Empire. Led by its young emperor Gulcasa, Bronica's armies defeated one Fantasinian army after the other. A large chunk of Fantasinia's territory was lost, many of its citizens had suffered from Bronican atrocities and eventually the king died. As the imperial capital is falling into enemy hands, a young girl by the name of Yggdra is escaping the city. A member of the imperial family, she is carrying the legendary sword Gran Centurio which was once wielded by the kingdom's founding father. With the sword Yggdra manages to safely make her way to the southern tip of the continent, where she meets the King of Thieves, Milanor. Together the two will try to defeat Gulcasa and reclaim the lost throne of Fantasinia.

Yggdra Union: We'll never fight alone will be available in Japan sometime in spring 2006.
