The Diamond Kingdom lies north of the Clover Kingdom. This country of mines and wasteland is poor in resources, so it focuses its efforts on building up its army and invading other countries to steal land and resources. Mage Scholars perform human experiments to bolster the power of the Mage Warriors 「魔導戦士 Madōsenshi」.
The Diamond Kingdom sends a team, led by Lotus Whomalt and Mars, to a dungeon that appears along the border with the Clover Kingdom. Although the team is defeated in battle by Magic Knights from the Golden Dawn and Black Bull squads, Lotus successfully escapes with his men and a large amount of treasure.
