Daiki, who started the popular game "Frontier World", chose a summoner as his profession. The summoner was called a landmine worker because the magic stones required for summoning were expensive, but summoned beasts didn't like him, but when Daiki generated magic stones on his own and summoned him, what appeared was... A high-status demonic little girl, and what's more, she's been on her shoulders from the beginning! A heartwarming VRMMO fantasy is here!
