*Contains smut, beware.
Ken, the Undefeated Mage, takes on the mission to break past the world's limits for its denizens. He fails, again and again until deciding to take a leap of faith and stages a suicide.
Many years pass, and The Undefeated Mage becomes a title few remember, until one day, the revival plan he left for himself takes effect. The new Ken is a changed man, with a vision that outstrips the boundaries of the realm. He embarks on a new path of power, his heart set in stone.
But the heroines have a say in it, as it involves Ken breeding them to the best of his capability; which means Ken's journey to the top of the world this time shall be filled with brutal seggs.
