Mukouda Tsuyoshi has been summoned from modern Japan to a different world of sword and magic. He eagerly thought of what kind of a huge adventure was waiting for him, but actually, Mukouda is just a civilian who got caught in a Hero Summoning. On top of that, Mukouda's base status is shabby compared to the legitimate heroes. Suspecting the king of foul play, as he's morbidly obese in a kingdom in crisis, apart from being war-happy, Mukouda decides to leave the castle by presenting his lack of martial prowess. The only thing that Mukouda can rely on in this world is his unique skill Net Supermarket, that can only order goods from modern Japan's internet to the new world.
