Even in this day and age of the 21st century, many gods live amongst humanity. Mayu is a cat god who is the master at finding lost objects, but she is very lazy and all she does all day is eat, sleep, and play video games. Mayu lives with her caretaker, Yuzu, who operates a pottery store while at the same time doing everything for Mayu. The pair meets other gods in their daily lives and have exciting adventures.

On January 3rd, 2097, a collision with a celestial object basically destroyed human civilization. Seventy years later, human survivors are still living in space, unable to return to their home planet. Some humans, called "Divers" are able to project an avatar to the earth in order to salvage information from earth-based computer networks.

Suzuro is a 14-year-old freelance diver of incredible skill, but only a C-rank due to age restrictions. She works in a salvage ship with her pilot Ginga, who keeps the ship out of flying debris while she's connected to earth, and her assistant Shimugi. It's not only space debris colliding with the ship that could kill Suzuro while diving, there are also dangers waiting on earth that could kill her, just by interacting with her avatar. Suzuro must be certain that the cases she takes are worth the danger!

An unknowing Sudou Kaname is invited to try out a new mysterious mobile app game called "Darwin's Game", but later realizes that he's in for more than he's bargained for when he finds out that there's no way to "quit" the game.
