One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence.

Living carefree at home is the greatest shortcut—- My house is the world’s greatest magic power spot, that being the case both my house and I were summoned to another world by some guys who were aiming for it. However, I’ve been living in this place for many years and my body is, apparently, abnormally overflowing with magic. Due to some unforeseen circumstances by those guys who summoned me, they quickly ran away. Be that as it may, there are some ill-mannered people who covet the magic leaking out of my house.

When Kazura was investigating the place that would become his shelter, he stumbled on a certain room where it was possible to go into and back from another world.
