Demonion 2: Maou to Sannin no Joou  

デモニオン2～魔王と三人の女王～

The nomads established four nations in what was previously a deserted area known as Nilt. These were Lusario, an Elven kingdom; Shuka, an Eastern empire; Kilos, an ice empire; and Hados, a dark demon realm. However, Hados disintegrated due to a human-instigated rebellion. A century later, the Diabolica were perceived as harbingers of devastation and turmoil, and they faced discrimination and suppression. Caym, a surviving Diabolica prince, resided in seclusion following the collapse of Hados. Risbell, a young girl, visited him and implored him to resurrect Hados to safeguard the Diabolica and avenge her parents' deaths at the hands of humans. He vowed to conquer the three nations and make their rulers his subservient servants.
