The Principality of Rossvale is a small, newly risen state where radicals had succeeded in gaining independence from the Holy Kingdom of Lugia. Whether in military or economic strength, the new state is quite behind compared to the surrounding countries. Hence they are resolved to raise the prestige of their country through achieving spectacular results at the «Blade Dance» festival.

The representatives for The Principality of Rossvale at the Blade Dance were the Team Rupture Division with Milla Bassett as team leader.
