Pocket King

As the local lands are being invaded by the army of the Demon Lord, the lone protagonist meets a creature called Pukuru. Together they meet the prince of the lands, who entrusts the protagonist to take command of the kingdom's army and combat the Demon Lord.

Pocket King takes the player across the continent. In each region, the player utilizes the services in settlements, and builds up an army from summoned monsters (costing MP) and soldiers in order to combats monsters of the demon army and ultimately liberate the infested region by meeting a certain condition. Units in the player's army can level up and carry over to other regions. Depending on the order the player takes to clear the continent, one of three endings are triggered.
