InkVortex

In a world constantly threatened by monsters and catastrophes, Kazuto was just an ordinary man living a dull, uninspired life—until he got fired from his job and lost all sense of purpose. Empty and unmotivated, his fate changed the day he crossed paths with Riku, a 15-year-old boy carrying a letter of utmost importance for his father.

As they chatted, a grotesque monster attacked, enraged over a hilariously petty grievance: someone had scribbled insults on its back during its transformation. Determined to protect Riku, Kazuto confronted the monster, rediscovering a spark of heroism he'd long forgotten since childhood. Against all odds, he defeated the monster using sheer wit, saving Riku, who thanked him before continuing his journey.

Inspired by the encounter, Kazuto made a life-altering decision: to train beyond human limits and become the strongest man alive. After three years of grueling, almost absurd training, Kazuto’s strength reached unimaginable levels. Now, he can obliterate any threat with a single punch, but his overwhelming power has left him trapped in a life of boredom. With no challenges, no glory, and no recognition, Kazuto finds himself facing a new kind of enemy: monotony.

Everything changes when Tatsuya, a young and stoic cyborg, clashes with a monstrous insect in a fierce battle. Despite his incredible power, Tatsuya is on the brink of defeat. At the last moment, Kazuto steps in and annihilates the monster with a single blow. Awestruck by Kazuto's overwhelming strength, Tatsuya pleads to become his disciple, convinced that this man holds the key to reaching perfection in his own quest for power.

As Kazuto navigates his apathetic routine, Tatsuya's fiery determination to grow stronger and their constant encounters with absurdly powerful monsters begin to inject a new sense of purpose into his life.
