I transmigrated into the body of a Demon King, and my subordinates are so loyal. Life should be great, right? What do you mean I transmigrated into a romance novel about a Demon King and a Hero? No way! Watashi doesn't want to be conquered by the Hero! What do you mean the previous Demon King's mother ran off to enjoy herself outside the Demon King's castle? What do you mean that as the Demon King, I have only pure Light magic, so I can't get stronger in the Demon King's castle? And these loyal subordinates have come up with an absurd way for me to get stronger: become a Hero? But this ridiculously muddled plan actually worked?! Hahaha! The real Hero got written out of the story, so now I'm invincible. Huh? What do you mean the Hero, whose name and attributes were never mentioned in the original story, is actually the sorceress in the Hero's party I put together? What do you mean I invited you into the Hero's party and gave you a path toward the future, so now you're in love with me? I-I'm the Demon King, so I... I would never accept your confession!
