In a world on the brink of chaos and wars, anyone with a weapon in hand can start a true legend, and Zephyr, just an ordinary hunter, knew that all too well.
Blinded by greed, he ventured into the world of mercenaries, only to find himself, as expected, on the verge of facing death on his very first mission, betrayed by his companions and confronted by a mysterious and powerful monster.
"... Become my heir and restore the glory of my race, or die here in vain. Make your choice, human."
Seeing the monster's power, his response was immediate, and thus, through the monster's death, without anyone knowing, an even worse monster was born, and so, a dark legend began.
This is the story of Zephyr Levka, the human who, driven by his greed, walks the path to becoming the almighty demon lord.
