"Life hacks" take on a whole new meaning when two students exploit glitches that distort reality!

Hitsujiya’s life is forever changed when his high school friend Kokudo reveals the secret of "hacks." By performing specific instructions found in a mysterious notebook, reality itself can be altered. While it seems funny or innocuous at first, they quickly learn there’s a dark side to the hacks, and they’re not the only ones who know about them.

When Kokudo introduces Hitsujiya to the strange world of hacks, it’s all fun and games at first. They learn how to make stray cats like them, how to make clouds disappear, how to see people’s auras. But when Kokudo uses a hack to go back in time to get a perfect score on a test, things take a turn. Hitsujiya attempts to do the same thing, but in the world of hacks, if the directions aren’t followed precisely, it can have devastating consequences!
