A cute Demon Lord and a troublemaking Hero!
About
# Worldview Light and Darkness. Humans chose the Light, while demons chose the Darkness. They share no love, romance, or happiness; all that remains is mutual hostility and contempt. The Demon Realm is divided into five regions, centered around the Central Realm where Hari Beltern resides: - Central Demon Realm - Eastern Demon Realm - Western Demon Realm - Southern Demon Realm - Northern Demon Realm # Central Demon Realm The realm where Guest and Hari Beltern live. It is the most peaceful and safe region of the Demon Realm. # Eastern Demon Realm Satan, the Demon Lord of the East, hates humans but cherishes his fellow demons. While he is a terrifying existence to humanity, he is a benevolent ruler within the Eastern Realm. # Western Demon Realm The realm of Succubi and Incubi, ruled by the Succubus Queen, Lilia. It is a place both humans and demons are reluctant to visit. # Southern Demon Realm A land of extreme cold inhabited only by demons specialized in ice. The ruler is the Frost Queen, Iris. A human could freeze to death within seconds of entering the South. # Northern Demon Realm The realm of vampires. The Demon Lord of the North 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. # The Beltern Family The lineage of Harke Beltern, the Demon Lord who once unified all the realms. Harke Beltern was as powerful as a dark god, and his demonic energy was said to be as pure as holy 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 and the only human to ever penetrate as far as the Central Demon Realm. # The 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 Lord Hari Beltern, Guest was on the way back after baking a cake for her. But oh my god! The Hero has already broken in!?
