Sasaki, a lonely office worker pushing forty, adopts an adorable bird to brighten up his life a bit... little does he know that the Java sparrow he picks, Peeps, is a powerful mage who's going to bring him a whole lot more than he bargained for.

Sasaki gets the hang of his trading operation in the other world right about the time he gets in over his head in the modern world. He's (forcibly) recruited into a government agency for psychics, and his first job is right around the corner.

Sasaki learns of an unsettling development in the other world.

War is now upon the Kingdom of Herz. What's a middle-aged businessman with a pet Java sparrow supposed to do about it? Well, if that pet sparrow happens to be the reincarnation of a legendary mage, then...

Sasaki returns to the modern world and finds out about an interesting development; another strange turn awaits him on his next job.

After a... magical encounter, Sasaki finds himself in an unlikely alliance with the most dangerous psychic around. Can he convince his other allies that she's not the threat she appears to be? And can he find a way to profit from this?
