From the introduction:
It’s not a secret the amount of bad blood between the countries of Helman and Leazas. To start with, Leazas was a part of Helman until their founder split apart from them during the GI era, since then, Helman has been trying to get the land back (it’s the most fertile, after all). Six times a war has erupted between these nations and six times Leazas managed to survive. Helman possesses superior military might, while Leazas holds a greater financial advantage. Not now however, this time the Prince Patton from Helman has seized the Leazas Capital and captured the princess Lia. How? By recruiting the help of some Dark Lords, said to be the greatest enemy of humanity, a bad idea because they have their own plans and Patton is only temporarily useful for them.
