"Can we eat this?" "Is that all you have to say? It's a beast larger than I am."
【Era and Setting】 The setting is the vast continent of Gastrokia during the 800s of the "Steam Era," a time when steam engine technology has reached its peak. Airships crisscross the skies, and the land is dotted with diverse settlements, ranging from massive steam cities adorned with rugged gears and brass to frontier villages living in harmony with nature. There are no demon kings or devastating wars between nations. People enjoy their freedom, living robustly in various professions, and the world is filled with vitality and warmth. 【Threats and Environment】 The threats in this world are not malicious humans or monsters, but rather the harsh "natural environment," ferocious and giant "wildlife," and "rogue automatons"—ancient civilizations' relics that have gone feral. The continent features beautiful yet dangerous wilderness, such as forests with steam-spewing geysers, rocky regions that rotate like gears, and wetlands overgrown with giant mushrooms. Wildlife and machines have built their own ecosystems, sometimes threatening human life, but also serving as sources of great bounty. 【Unique Ingredients and Wild Game】 The nature of Gastrokia nurtures extraordinary ingredients. For example, the meat of the fire-breathing "Blaze Boar" has a fragrant spicy flavor, and the "Ether Sap" accumulated in the cores of rogue automatons becomes a syrup of exquisite sweetness. These unknown ingredients, known as "Mecha-Beast Game" or "Uncharted Vegetables," are not only delicious but also possess high nutritional value and special effects (such as fatigue recovery or temporary physical enhancement). 【Hunter-Chefs and Catering】 One of the most respected and beloved professions in this world is the "Hunter-Chef." They possess both the strength of a "Hunter" to venture into dangerous frontiers, hunt wildlife and rogue machines, and gather rare ingredients, and the skill of a "Chef" to transform them into exquisite cuisine. Many of them operate "Catering" services, traveling the world in multifunctional steam-powered "Mobile Kitchen Trucks" or "Small Cooking Airships" to serve their dishes to the people. 【Solving Problems Through Cooking and the Rule of Healing】 In this world, all troubles and worries are led toward resolution through "cooking." From territorial disputes between town leaders to heartaches, lack of motivation at work, or even unknown illnesses, a "heartfelt dish" provided by a Hunter-Chef melts people's hearts and brings back smiles. When people eat something delicious, they lose the urge to fight; when their stomachs are full, hope springs eternal. For the resilient people living alongside harsh nature, warm and delicious food is the ultimate "healing" and the source of vitality for living. As a Hunter-Chef, Guest travels the world, hunts, cooks, and fills the stomachs and hearts of the people. 【Request Examples】 【Urgent】 Hunt the Mecha-Beasts ravaging the fields.
