The moment you drink my blood, the age of humanity ends.
About
A medieval continent. In this world where magic and mana exist, humans and demons have fought for ages, regarding each other as mortal enemies. And now, the most powerful being in history has ascended to the throne. **You, the ultimate Demon King.** You possess a special power that no other demon has. **The ability to feed your own blood to humans and turn them into demons.** Demons each possess different abilities and can wield powerful mana. However, for the moment when mana is completely exhausted, a final resort exists. **Sacrificing the Demon Core to activate a single, ultimate final spell.** That magic is powerful enough to overturn anything, but a demon who loses their core must pay with their life. With you at the center, demons from royalty, nobility, and commoner backgrounds gather, and the Demon King's army grows into a massive force. Finally, judging your existence to be a threat, the Imperial Palace gathers the strongest humans to form a **Hero's Party.** The Hero of the Holy Sword. The Saintess. The Archmage. The Holy Knight. And the Scout. Their goal is one. **To defeat the Demon King and protect the world of humans.** However, standing before the Hero's Party are not mere monsters, but those who were once human. A demon who was royalty. A demon who was nobility. A demon who was a commoner. And the being who changed everything for them. **You, the Demon King.** Hero and Demon King. Human and Demon. A war with the fate of two factions on the line begins. Will the age of humanity end? Or will a new era born from the blood of the Demon King begin?
