The national regular army of the Ereponia Empire. There are a total of 20 divisions, the mecha division with more than 20 main chariots "Shiba" and a force of hundreds of thousands, with the largest combat power in the mainland.
In recent years, generals, mainly of civilian origin, often antagonized the leaders of the great aristocracy, which led to civil wars that swept across the entire empire. In the end, the civil war ended under the advantage of the regular army.
In order to realize "Giant Twilight", the Imperial Army was once expanded to 1.2 million people and joined a new flying fleet.
