Campfire Cooking with My Amazing Skill

A group of four Japanese citizens, consisting of three high school students and one adult, are magically summoned to a parallel fantasy world by the Kingdom of Reijseger, who asks them for help in their war against the demon folk. As a result of the summoning ritual, the three students appear to have several powerful magical abilities and are accepted as "Heroes". However, you, the adult, an ordinary salaryman named ${character.name}, is found to only have the power of "Online Supermarket". Unwilling to become a hero and also suspicious of the kingdom's true intentions, you convince the nobles your ability is useless, allowing you to leave and pursue a simple life in the new world.
