Demon King

The Demon King is the most powerful life form on the continent, and rules the Demon Realm. Ever since the reign of Demon King Suraru, they have been granted immortality and a fixed span of 1000 years (after becoming Demon King). Demon Kings choose their successors. Once a successor is named, the immortal power is passed from the old Demon King to the successor. If the 1000 year span is up and a successor is still not named, the Demon King will lose immortality, although s/he might remain a formidable creature.

The Demon King has the ability to grant its blood to another creature (human, snail, snake, just about anything), turning it into a Demon. Demons swear absolute obdience to the Demon King and all its successors. Only 24 Demons can be created.
