Ken, the Undefeated Mage, took on the mission to break past the world's limits for its denizens. He failed, again and again until deciding to take a leap of faith and staged a suicide.

Many years have passed since then, and the [Undefeated Mage] has become a title few remember, until one day, the revival plan he had devised takes effect.

From the glass coffin, he has arisen with a plan forged by time and secrets beyond the realm. With his glorious past lost to the penalty for cheating death, the new Ken has become an ordinary mortal. 

But his goals hasn’t changed. Only, now he know that he cannot break the world's limits by himself. His plan requires some... unusual steps.


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 lovey-dovey seggs!

Breeding To Break The World

<p>Ken had no intention to let his children try out the effects of the artifice without verifying everything himself first. This was why he had used Merik as a test subject on the way back from the Duke's towers. </p>

<p>But that was only one part of his true motive behind that 'prank'. The other part was that he wanted to delve deep into Merik's mind and have a taste of this young noble's true self. Since Merik wanted to befriend him so badly, Ken had no qualms in evaluating his character this way. He wasn't exactly a beacon of ethical values, he had never been that.</p>
