The Yandere Demon Lords & Me - Chapter 3: The Tea That Doomed the World -

When a terminally ill young man awakens in the world of his favorite childhood game, he realizes he isn’t the protagonist, the destined hero, or even a major side character. Instead, he has become an extra—a disowned noble barely clinging to relevance in a world where strength determines everything. Worse, his fate in the game was to die an early, meaningless death.Armed with only his knowledge of the game’s storyline and a common system that tracks his stats and skills, he is determined to survive. But mere survival isn’t enough. He remembers a hidden easter egg from a long-forgotten anime collaboration: the Mangekyō Sharingan—a power limited by game mechanics but unrestricted in reality.With Kamui as his trump card, he walks the fine line between fate and freedom, seizing power from the shadows while avoiding suspicion. As the protagonist and his allies battle against demons and unravel the game’s grand destiny, he secretly builds his own strength—manipulating events, mastering forgotten arts, and even forging ties with villainous factions.Will he remain a footnote in history, or will he carve his own legend in a world that was never meant to be his?

I'm captured? Fine, I can't help it since I can't move.

Experimented on? At least give me some anaesthetic.

I'm freed? Let me get some revenge.

Want to plead for your life? Sorry, this miss here holds a grudge.

I destroyed the lab so now let me explore this world freely.

I somehow joined Mr Hero's party. Fine, he seems fun.

"Aiya, how cruel. For the honour of being a hero you'd kill this missy huh?" She smiled whilst bleeding out.

"Che, you still have the mind to joke right now?" He said with a glare.

"What is life if not to enjoy every moment? Since I'm going to die and I can't avenge myself, I hope someone else does."

"No one will. You were the only one who was more powerful than I with your Nanomancy. Now with you out of th-"

"Hush child. I'm trying to die in peace here."

"But I'm ol-!"

"Ap! Good children don't disturb their elders."

"But yo-!"

"Bye~" She grinned before losing strength.

"FUCK!"
…

Mr Wolves are growling at me. Hungry huh?... Me too.
