Hugh Pnosis is a young boy carrying the heavy memories of his previous life as an exhausted corporate worker. Reborn into a new world, his only desire is to enjoy a peaceful, carefree existence far removed from stress and overwork. However, fate grants him a deeply unsettling ability: the "Brainwashing" skill, a terrifying power that allows him to completely dominate the minds of anyone he targets. Lacking any ambition to exploit this dangerous gift—let alone manipulate beautiful women into forming a harem—Hugh resolves to keep his ability an absolute secret, knowing full well that discovery would likely lead to his execution. He swears to live an honest, upright life without ever misusing the power he has been given. Yet, while trying to remain virtuous, Hugh stumbles upon a staggering loophole in his own abilities. By casting Brainwashing on himself, he discovers he can freely rewrite, alter, and swap out his skills at will. This broken, cheat-level trick transforms his cautious approach to survival, setting the stage for an unexpected adventure where his determination to live quietly begins attracting attention he never sought.
