Makoto Kenji, an overworked and perpetually underpaid office worker, is unexpectedly transported to a parallel world alongside several coworkers. Upon arrival, they are tasked with saving this new realm from the devastating onslaught of a demon king. However, when their unique abilities are assessed, Kenji discovers he possesses the animal tamer class—a role considered lesser than traditional beast taming, limited to controlling only dogs, cats, and the occasional bird. Deemed insufficient for the world-saving mission, Kenji is cast out, though his dismissal comes with considerable compensation in gold. Rather than despair, he rebuilds his life by leveraging his mundane cooking skills, which prove extraordinarily potent in this world. A simple dish of rice and curry grants those who consume it enhanced vitality, enabling rapid advancement through the rank level system. His culinary talents bring both wealth and widespread fame. Yet despite his newfound success and prosperity, Kenji grows restless. Seeking new challenges and thrills, he abandons his comfortable merchant existence to become an adventurer. During his first quest, an unexpected encounter occurs—a pivotal moment that will forever alter his destiny and transform the very fate of the entire world.
