Also known as The Bad Girl's Guide to Self-Cultivation: The Demon King Is a Yandere
The newly appointed Demon King was so obsessed with romance novels that he sneaked into one to experience the thrill of being a domineering CEO. The poor retired Demon King was forced to keep making babies, while sending out the Demon Ring to find this willful ruler of the demon realm.
The Demon Ring, in the midst of its miserable search, happened to save Su Tang, who was about to kill herself, and ended up dragging her along too.
In this endless sea of books, with billions of characters, where should they even start looking?
Su Tang: Does your Demon King have any distinctive traits?
The Demon Ring pondered for a moment: He's... a yandere.
Su Tang: What a nightmare! We have to search the whole city for a yandere pervert!
But as they traveled together, the Demon Ring gradually began to notice: why was this adorable girl, who had once been so sweet, becoming more and more like their young master?
Young Master, you're done for.
Are the male and female protagonists both clean?
