The Demon King’s Guide to Sterilization

Aldous is an incubus and a scholar. Ever since the incubus race was driven into the Abyss and lost humanity as an easily acquired, plentiful food source, he has shouldered the burden of restoring his race all by himself, diligently studying the [beep, ], [beep, ][beep, ], and [beep, ][beep, ][beep, ][beep, ] of various races. All he wants is to find a new, reliable, safe food source in the perilous Abyss, so his race won’t starve to death. At last, after succeeding, Aldous sank into the soft lounge chair in his laboratory and suddenly felt a loneliness he hadn’t known for a long time. Burettes and petri dishes have no warmth. Aldous decided to get a pet, a soft, harmless little thing. As luck would have it, he found a cat. ** Thorn is the Demon King of the Abyss. Even a thousand years after his death, his legend is still widely told: powerful, violent, wild in life, and dead under mysterious circumstances. No one realized he had been resurrected in a remote mountain ravine, turned into a harmless cat. Thorn had mentally prepared himself for what he’d find after coming back to life. He thought he would have to endure a long recovery, find the weapon he’d lost somewhere, and face all kinds of attacks from the traitors. He never expected his first challenge to be figuring out how to protect his balls from the incubus in front of him. “A boy.” The incubus expertly weighed the cat by its bell. “Let’s get you neutered before you go into heat.” But can someone tell him who came up with the idea of neutering a cat?! Huh?!! Thorn roared, letting out a soft, fluffy meow: “Meow~” #The Demon King was resurrected, but halfway through, he nearly lost his balls# 1.
