I Customized My Way to Becoming the Demon King

Haruto Tanaka, an otaku obsessed with isekai, finally saw his chance—Truck-kun was coming straight for him! Ready to embrace his destiny, he spread his arms… only to be pulled back by a random bystander.



Humiliated, he returned home, convinced his dreams were over—until he blinked and found himself in a grand throne room. A goddess welcomed him, but instead of becoming a hero, he was chosen as the new Demon King.



With a broken hero-to-villain ratio and too many truck-induced reincarnations, the gods needed balance. Given full customization of his abilities and power, Haruto grinned.



If he couldn’t be the hero, he’d become the strongest Demon King ever.
