Youjo na Majo to Mori no Kuma-san: Isekai de Potion Tsukutte Nonbiri Slow Life ga Shitai no jaga?

When a catastrophic collision between Earth and another dimension triggers a devastating bus accident, a man nearing forty finds himself facing an extraordinary choice. He can either return to his original world with the tragedy completely erased from existence, or begin anew in a fantasy realm equipped with a specialized profession known as a Class. With few meaningful attachments left behind, he opts for reincarnation. Unfortunately, the most prestigious roles—Hero and Great Sage—have already been claimed by others. Scanning the remaining high-tier options, his attention is drawn to an unusual title: Potion Master. Exhausted by the relentless pace of modern life, he envisions brewing elixirs deep in the wilderness as the perfect path to a tranquil, slow-paced existence. His dream of peaceful retirement shatters almost immediately upon discovering that the Potion Master class is absurdly overpowered. In a bizarre twist of fate, he uses one of his own concoctions to transform into a young witch, quickly forming an unlikely bond with a fearsome magical bear. Rather than enjoying a quiet life on the fringes of society, she finds herself entangled in the complex affairs of this strange new world far beyond what any relaxing lifestyle should demand. Thus unfolds the decidedly chaotic and action-packed journey of an overwhelmingly powerful little witch and her monstrous companion navigating their unexpected adventures together.
