The Corporate Slave Reincarnates as the Strongest Demon Dragon and Becomes the Hero's Master

After working himself to death at a toxic company, Takeuchi reincarnates into the fantasy continent of Edram—not as a human, but as the world's strongest Demon Dragon! There, he crosses paths with a party of bumbling heroes who are so awestruck by his overwhelming power that they beg him to be their master. Takeuchi learns that this world's peace is supposedly maintained by the "Hero Association," a massive organization led by a Saintess. But there is a dark secret: the Association is a toxic, exploitative nightmare that treats its heroes worse than corporate slaves, draining them of tribute money and magic items! Sympathizing with his new disciples and refusing to repeat the regrets of his past life, this former corporate drone unleashes his dragon powers to completely revolutionize the fantasy workplace!
