Suzaku Kururugi, Euphemia Li Britannia, along with Simon and Nia Teppelin are brought to the realm of Equestria by some unknown force of redemption or fate. For the most part, they know nothing of how they arrived or what awaits them in this world.

After their rescue from the Everfree, the two couples must adapt to a new world, one of friendship, harmony, and magic in the place of their home realms.

However, a new threat long vanquished has begun to awaken, and it is coming with a vengeance to conclude his unfinished business. Nothing that two mecha pilots can handle, right?
