From J-Novel:
The Cultural Research Club is an eclectic bunch: a pro wrestling fanboy, a goofy ditz, a master of snark, a laid-back jokester, and a total girly girl. Their peaceful teenage lives are turned upside-down, however, when they suddenly and inexplicably start swapping bodies with each other.
At first, it's all wacky hijinks but then things get a little too personal. Boundaries are crossed, and dark secrets come to light secrets that threaten to destroy the very foundations of their friendship. Who or what is causing the body-swap phenomenon? Will it ever stop? But most of all can their club survive it?
