Tasuku Motokita, an ordinary office worker, tries to log in to <Lab>, an open-world building game, today as well. ……But suddenly he loses consciousness. When you wake up, you will find yourself in a world where grasslands spread all over. I tried to open the status screen, thinking, "This is... a so-called transfer to another world?", but it didn't open. However, just like <Lab>, he discovers that he can use super-convenient "skills" that turn objects into materials and make anything by hand. Tasuku realizes this and builds huts, furniture, lush green fields, stone baths, and other necessities one after another to start a self-sufficient life in another world. A task that makes me happy to create "my territory" in a different world where there are no ties, compared to when I was a busy and low-paying office worker. With him comes a group of unique companions, such as the dependable cat race Isla, the gal-type black elf Bell, and the gluttonous high elf Elise!?
