I Create Kasukabe City to Resist Ghosts and Gods!

I, Shunsuke Nohara, discovered that my girlfriend, Yao-chan, is the eldest daughter of a super top and invincible chaebol. I thought I would be able to make a living in this life, but you told me that her family is actually a family of hidden guardians who resist eight million ghosts and gods and maintain the safety of reality? Etc? The way the Hidden Guardian family resists ghosts and gods is to create a special world to trap ghosts and gods. And the higher the level of detail in creating the world, the stronger the world will be? Shunsuke Nohara thought of countless anime in his previous life, and it seemed that creating a world was not easy... And seeing that the girlfriend family is in danger and is about to face the risk of bankruptcy, they can only use their last savings to create a realistic world to resist ghosts and gods. Nohara Shunsuke thought of a certain classic anime, the kid who was said to be extremely sinister... It seemed that in that drama, all the monsters and monsters that appeared in that show would be defeated in front of that kid! The decision is made by you, Crayon Shin-chan's Kasukabe City, go out! ——Nohara Shunsuke said this.
