For fans of the "zero-to-hero" trope and high-stakes fantasy, few titles capture the essence of grueling perseverance quite like "I Kept Pressing the 100-Million-Year Button and Came Out on Top" (Japanese: *Ichioku-nen Button o Renda Shita Ore wa, Kizuitara Saikyou ni Natteita*). Originally a light novel series by Shuichi Tsukishima and later adapted into a popular manga by Syu, this story takes the concept of a "training arc" to an absolute, existential extreme.
The Plot: A Billion Years of Solitude
The story follows Allen, a student at the prestigious Grand Swordcraft Academy. In a world where magical aptitude and lineage determine one’s worth, Allen is a social pariah. Labeled the "Reject Swordsman," he possesses abysmal magic capacity and seemingly zero talent for the blade. Despite his relentless effort, he is constantly humiliated by his peers, most notably the arrogant noble Dodriel, who challenges Allen to a duel where the stakes are nothing less than Allen’s expulsion.
On the verge of despair and certain defeat, Allen encounters a mysterious, shady hermit who offers him a peculiar artifact: a button. The premise is simple yet terrifying—every time the button is pressed, the user is transported to a pocket dimension where they must spend 100 million years training. In the real world, however, not a single second passes.
Driven by a desperate need to protect his future and his mother’s pride, Allen presses the button. Then, he presses it again. And again. What follows is a psychological and physical odyssey as Allen spends billions of years in total isolation, practicing the same basic sword swings until his mind nearly breaks and his body transcends human limits. When he finally returns to the real world to face his rival, he isn't just a better swordsman; he is a man who has mastered the flow of time itself through sheer, agonizing repetition.
Demographic and Genre
This manga falls squarely into the Shonen demographic. It is serialized in *Young Ace Up*, targeting a younger male audience but appealing to anyone who enjoys battle-centric narratives. It blends elements of Fantasy, Action, and School Life, utilizing the "Magic High School" setting that has become a staple of modern Japanese media. However, it distinguishes itself by leaning into the "overpowered protagonist" (OP) subgenre with a unique temporal twist.
Main Themes: Talent vs. Time
The core of *I Kept Pressing the 100-Million-Year Button* revolves around the classic debate of Innate Talent vs. Hard Work. Allen represents the ultimate underdog. Unlike other protagonists who are born with secret bloodlines or "cheat" abilities, Allen’s power is earned through a duration of time that is incomprehensible to the human mind.
Another major theme is Isolation and Mental Fortitude. The manga explores the psychological toll of spending eons alone. While the "button" provides power, it also highlights the tragedy of Allen’s sacrifice; he has lived countless lifetimes in a void just to win a single moment of respect in the real world. This adds a layer of melancholy to his character that isn't always present in standard power fantasies.
Why You Should Read It
For SEO purposes and reader interest, it’s important to note that this manga excels in power scaling and catharsis. There is a profound satisfaction in watching a character who was once mocked for his "slow" movements suddenly outpace the fastest warriors in the kingdom. The art style effectively conveys the weight of Allen’s "God-speed" techniques, making every duel feel like a monumental event.
If you are looking for a series that takes the "grind" of RPGs and turns it into a cosmic-level epic, this is the manga for you. It’s a testament to the idea that even the most "untalented" person can reach the pinnacle of greatness—provided they have the soul to endure a hundred million years of practice.
