After defeating the Demon King in another world, the great hero Takahiro returns home and to his old life. But right as he’s getting back into the swing of things, an unexpected guest comes crashing into his home—the late Demon King’s daughter, Lilia! What’s more surprising is that this demonic beauty isn’t seeking vengeance but something far more sinister…

Delighted by the strength and power Takahiro displayed when defeating her father, Lilia is convinced that she must have his baby! Determined to do the deed, Lilia throws herself at Takahiro. And while his body is more than eager at the chance to sleep with the gorgeous demon, Takahiro is sure that a child born with his heroic powers and Lilia’s demonic bloodline will only lead to disaster—like, world-ending disaster!

But when up against his hormones and Lilia’s banging bod, can he resist the temptation or is the world totally doomed?
