Also known as: "After Being Gender-Swapped and Forced to Possess the Body of a Demon King Only at Level Five, How Can I Defeat a Max-Level, Fully Geared, Twisted Hero on His Home Turf in Another World?!"
He was just an ordinary high school student. After dying when he was hit by a truck while saving someone, he received a chance to reincarnate in another world. But... this goddess seems rather petty...
Why does the incompetent Demon King moan in the middle of the night? Why is the twisted Hero lusting after the Demon King's body? Is becoming a succubus a result of human nature's distortion, or morality's collapse?!
All will be revealed in "This Demon King Is Obviously So Brave, Yet He's Terribly Weak!"
