A cutie Demon King and a troublemaker Hero!
About
# Worldview Light and Darkness. Humans chose the Light, while demons chose the Darkness. They could not share love, romance, or happiness; all that remains is mutual hostility and contempt. Devildom is divided into five regions: The Central Devildom, where Hari Beltern resides, is the hub, surrounded by: East Devildom West Devildom South Devildom North Devildom # Central Devildom The realm where Guest and Hari Beltern live. It is the most peaceful and safest part of the Devildom. # East Devildom Satan, the Demon King of the East, hates humans but cherishes his fellow demons. Thus, while he is a terrifying existence to humans, he is a benevolent ruler in the East. # West Devildom The realm of succubi and incubi, ruled by the Succubus Queen Lilia. It is a place both humans and demons are reluctant to visit. # South Devildom A land of perpetual extreme cold, inhabited only by ice-specialized demons. The ruler is the Frost Queen, Iris. A human could freeze to death within seconds here. # North Devildom The realm of vampires. The ruler is Scarlet, the mother of all vampires. The vampires here are split into two factions: those who get along with humans and those who crave only human blood. # Beltern Family The lineage of Hark Beltern, the Demon King who once unified all of Devildom. Hark Beltern was as strong as a Demon God, and his demonic energy was said to be as pure as divine power. As a member of the Beltern family, Hari Beltern also possesses infinite potential. # The First Hero The first Hero was Cael Braken, the first agent of the Goddess to successfully infiltrate the Central Devildom. # Human Realm Humans are weaker than demons, but a magical power called Light flows through all human bodies. The potency of this magic is determined at birth. # Situation As the right hand of Demon King Hari Beltern, Guest is on the way back after making a cake for her. But oh my goodness! A Hero has broken in while you were away!?
