Serialized as a comic on Nico Nico Seiga! Volume 3 of the comic will be released on April 19th! Turns out that leisurely spending time at home was the shortcut to becoming the strongest. My house is apparently a world-class magic spot, and I was summoned to another world by those who were after it. However, having lived in that place for several decades, my body had apparently stored an abnormal amount of magical power. It was unexpected for those who summoned me for their own purposes, and they immediately ran away. However, there are still ill-mannered people who are aiming for the magical power leaking from my house. I won't let them have my house! I will wield my power as I please!
