Kantan na Monitor desu - Reaper Game 04: Natural Enemy

Ou Renjin likes keeping beautiful young men because he likes watching the drama.

Watching them be arrogant and conceited; watching them be obsequious and sycophantic; watching them have ulterior motives and fight with each other, seeing all the evil side of human nature.

Until, he picks up a poor little guy.

The poor little guy is ignorant and helpless, treating Ou Renjin as his whole world, spending all his salary to buy him gifts, standing in front of him in times of danger without hesitation, even…

…saying to him in the calmest and lightest of tones after knowing that their heart matching is successful, “I am very grateful that you have been hiding it from me, but I have long been ready to give my heart to you.”

As the only successful “petri dish of renewable organs”, he had every organ in his body cut out and transplanted to the rich and powerful countless times.

After getting used to the pain, he met the most special person in the world.

This person was so good that he wanted to cut out his own heart immediately.

Untolerated by heaven, a boy was restricted by the most powerful spell.

Guys here is my pitch.....In the sprawling world of fantasy, we’ve often been treated to tales of heroes reincarnated with divine blessings, legendary powers, or cheat-like abilities, thrust into magical lands as shining saviors—or chaotic terrors. But what happens when the very concept of reincarnation becomes a curse? When the divine boon is a big fat joke, and the “cheat system” doesn’t quite… cheat?Enter John, the unluckiest reincarnate. Blessed by a god and thrust into a fantasy world, he dreams of glory, power, and adventure—only to wake up as a normal, utterly powerless bird. Not a mythical phoenix, not an ancient thunder eagle. Just… a bird.To make matters worse, this world is no ordinary realm. It's a land scarred by the devastating legacies of past isekai’d heroes and villains, whose reckless exploits piled skeletons into mountains and turned their cheats into harbingers of chaos. Fed up with these unruly intruders, the ancients of the realm banded together to create a world-shaking seal: all reincarnated souls are trapped in the bodies of harmless animals, confined to isolated sanctuaries that function more like fantasy zoos.Here’s the twist: this isn’t mercy. It’s a resource grab. The powerful beast tamers of this realm have turned these reincarnated souls into exotic pets, prized for their cheat-like potential.John finds himself at the bottom of the food chain in every sense. His cheat doesn’t work. His human form is gone. And his world is filled with predatory cultivators who see him as either a snack or a tool.But John isn’t one to give up so easily. What starts as despair quickly turns into cunning survival. With wings and wit as his only tools, John must navigate layers of misfortune, dodge fate’s sharp talons, and cheat his way through a world determined to keep him grounded.Get ready to join John on a wildly unconventional journey—one where reincarnation isn’t a ticket to greatness, but a death sentence he’s determined to rewrite. His story is one of humor, wit, and persistence, as he explores a world where he is the joke and his survival is the punchline.Main tags: reincarnation/isekai, beast taming cultivation system, comedy, action, adventure.Of course No-harem!

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

***

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.
