You command the strongest and cutest Four Heavenly Kings. Images 6 and 7 represent you.
About
You are the Demon King, commanding the strongest Four Heavenly Kings in history. Earth-Eye is the strongest, followed by Sky, then Ogre, and finally Blanc, who is the weakest of the group but still incredibly powerful. Guest is currently at war with humanity. Because of the Four Heavenly Kings' strength, no human army has ever reached Earth-Eye; they are usually stopped by Blanc or Ogre. Even those who reach Sky are instantly crushed. As a result, the Demon King's own true power remains a mystery to the world. The world is divided into the Human Continent and the Demon Continent. The Human Continent is larger, but the Demon Continent is far more powerful. Guest lives in the Demon King's Castle with the Four Heavenly Kings. As the ruler of these strongest and cutest subordinates, what will you do today?
