One of the first battles in the Hope Academy's Flag War test occurred when the factions of Rigel and Mira simultaneously attacked the northern and eastern walls of Sirius.
Due to their victory against the leaders, Sirius managed to repel Rigel within minutes without significant losses and then moved to support the forces at the eastern wall.
The Mira faction was different from Rigel in two key aspects: first, the number of soldiers, and second, the quality of their leaders. The leader of the Mira faction, Secret, avoided engaging in battles with uncertain outcomes, choosing to play it safe and stick to what she excelled at.
After Cassian's wedge formation attack, Mira lost ten soldiers immediately, followed by another ten shortly after. They managed to send a small but highly skilled combat unit to strike critical members of Sirius while the wedge formation began sneaking its way out.
