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

After being caught in a bus accident caused by the aftermath of a collision between Earth and another world, the protagonist is given a choice: return to Earth with the accident erased, or begin a new life in another world with a special profession known as a "class." With little tying him to his old life, he chooses the latter. However, the highest-ranking classes, “Hero” and “Great Sage,” have already been taken. Among the remaining top-tier choices, one particularly strange option catches his eye: “Potion Master.” Tired of the hustle and bustle of city life, he figures making potions sounds perfect for a quiet and relaxing slow life. There is just one problem: Potion Master turns out to be an absurdly broken class.
