◆

A certain wholesome middle-aged man, Kenji, installs a mysterious smartphone app called "A Guide to World Creation."

It's a game that allows him to freely manipulate everything—planets, life, races, eras, and more.

But thanks to a new feature, he transfers himself into the on-screen world and can now travel freely between it and Japan!

In the other world, he can replay events and time travel. The special abilities he gains can be used in either world, and with dimensional storage, he can carry objects and even people limitlessly...!

"Hmm, it'd be a waste not to go on an adventure, wouldn't it?"

While busy solving problems in both worlds, he levels up in his spare time.

Occasionally, he issues divine revelations that rock the other world, or even tames a nine-tailed fox girl with tuna-mayo—?!

Following his whims wherever they take him, the former salaryman's "anything goes" god-like life BEGINS!
