Roland transmigrates to the Holy Aize Continent and becomes a down-on-his-luck human lord in a border province.
His predecessor was violent and arrogant, drowning his sorrows in drink every day.
With his territory surrounded by gnolls and all hope seemingly lost, Roland decides to indulge himself before he dies. But after linking with a catgirl maid, he unexpectedly awakens the unique hidden talent [Lord of the Abyssal Succubi].
Roland is suddenly drained dry, while the catgirl maid evolves into the “Shadow Assassin Queen,” and her loyalty to him skyrockets.
Roland then discovers that by linking with beautiful nonhuman women who have great potential, he can grow stronger through “magical resonance” and grant them astonishing evolutionary talents. The more times he links, the more they can continue to evolve!
Thus, in order to survive in this war-torn world, Roland embarks on a path of conquest, gathering saintesses, elf queens, and dragon princesses to build the most powerful harem empire.
