Kokoro Connect

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? Find out in the hit ensemble dramedy light novel from award-winning author Sadanatsu Anda!
