MTL - Undying Patient - Chapter 120 Demon Concerto 15

Alex was an ordinary person with the dream of one day being transmigrated to a magical world.

But what he didn't expect is that he would be transmigrated to a world much more than that, a world he knew very well, but instead of being given a system that would empower him, he was given a system that allowed him to make games, and the more people played, the more powers he would get.

Tony Stark: I hate this! I can do in real life everything this Watch Dogs guy does, but why can't I stop playing?

Hulk: HULK HATES DARK SOULS!!! HULK SMASH DARK SOUS ARRRHHHHGGG!!!

Nick Fury: If any agent can't complete the Hitman game by next week, that agent will be fired from the Shield!

A world of superheroes, but who controls everything is "only" a game developer.

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?

“Isn't this the weak young master of the Valhalla family?”“Hahaha! I heard he only knows how to waste money... Completely useless.”Another voice, dripping with false pity, chimed in.“Both his sister and brother are Tamers, strong ones at that. While him... the eldest... pathetic!!”The final word, spat out like a curse, hung in the air: “Useless!”In this world, where the bond with powerful Beasts dictated one's standing, where strength was synonymous with the ferocity and strength of your companion.Christopher Valhalla was an anomaly. He found solace not in the thrill of battle or the acquisition of monstrous power, but in the simple, fleeting joys of life. He enjoyed partying, clubs, and women.He offered no retort to the cruel rumors that trailed him like a shadow. Because, truth be told, a knot of fear tightened in his stomach at the mere sight of the majestic, often terrifying, creatures that others commanded.But every life, regardless of its perceived worth, eventually finds its end. For Christopher, it came not in the jaws of a wild Beast, nor in a duel he was ill-equipped for, but in the insidious grip of a rare and incurable sickness.Some days later his flame flickered and he died, leaving behind a void filled with the echoes of scorn.Yet, where one life ended, another began. In the silent stillness of Christopher's vacant shell, a new consciousness stirred. A soul, bearing the weight of unmatched power and a reputation that sent shivers down the spines of even the most formidable Tamers, had arrived.This was the Supreme Tamer, a legend whispered in hushed tones across the world, a force of nature who had inexplicably perished at the hands of betrayal.Given this unexpected second chance, the Supreme Tamer, now inhabiting the frail form of Christopher Valhalla, felt a strange sense of acceptance. He looked upon the unfamiliar yet familiar faces of his new family – the concerned worry etched on their features – and a flicker of something akin to kinship sparked within him.A silent vow formed in his mind, hardening into an unbreakable resolve.The rumors that clung to this body like a shroud would be torn away. And the five Master Tamers who had orchestrated his demise in his previous life… They would learn the true meaning of fear.Their betrayal would be answered, not with petty revenge, but with the full, terrifying might of the Supreme Tamer, reborn. The world was about to discover that “useless” could be the most dangerous disguise of all.

“Hey, Yoshi-kun. I think you’re——”

Hearing that voice for the first time stopped me in my tracks. On my way home from school. On the playing field of our junior high, and at the bookshop in front of the station. And then in the empty lot where the white cat slept. Shiina Yuki, the strange girl who somehow knew all about me, always approached me like that.

We laughed, cried, got angry, held hands. Again and again, we repeated those disappearing memories and ephemeral promises. That’s why I never knew. I never knew the value of Yuki’s smiles or the meaning of her tears. Nor even the singular sentiment behind her many ‘Nice to meet you’s.

This is a captivating, heartrending tale of meetings and partings.
