“The protagonist is a caring older brother and his little sister, who loves her big brother dearly, who were both transported to another world. They lived in an old house far away from civilization, and suddenly, their house was also transported to this new world. After the transfer, they discovered that a part of their old house was now a newly built main house, connecting them to Japan. Although they gained incredible powers as a bonus from the transfer, they haven’t realized it yet. Protected by their sturdy home and their cheat abilities, they defeat monsters and level up, just like in a video game. They lead a life in the other world, using Earth’s items and sending items they obtain in the other world back to Earth.”
