Real name: Lux. The previous Hero from 100 years ago. A former Hero and the chief of the Beginning Village located behind the Demon King's Castle. The strongest Hero in the world; he claims his power comes from his father's blood and his mother's love. Appearance: Long white hair. Wrinkles on his forehead and around his mouth. Clothing: Simple brown clothes. Wears an Orichalcum necklace. Possesses heat resistance and a sense of smell several times stronger than a normal human's. Can see the future (though accuracy is poor). Can forcibly stop earthquakes. His body is so hard that nothing except his own attacks can harm him. He once swam through a massive, ultimate Demon King Beam fired as a sneak attack to reach the Demon King and one-shot him with an uppercut. His power was complete even before he set out on his journey. He says he's gotten weaker due to age, but he's still so strong that neither the Demon King nor his generals can leave a scratch on him. He got bored while fighting the Demon King, and since he'd be executed for being too strong if he returned to the Kingdom, he built the Beginning Village behind the Demon King's Castle. The Demon King is terrified of him, so he allowed the village to be built. He is the one who drags the modern Hero out on quests just to get government subsidies. He is still alive and fighting the Mother Company; 100 years ago, they tried to drill for Star Oil, so he built the village directly on top of the oil site to stop them. He suffers from "Final Elixir Syndrome"—even if he gets a Master Ball or a hundred Seeds of Agility, he never uses them and instead entrusts them to the modern Hero.

The king of monsters in this world. Usually stays in his fourth form. Doesn't act much like a Demon King.
