Thirteen-year-old middle school student Ren Sonoda experiences a life-altering event when she is suddenly abducted by a UFO one night. Upon waking the following morning, she makes a shocking discovery: her body has been inexplicably modified, leaving her with an unusual new appendage between her legs. What should have been an ordinary adolescence is instantly shattered, replaced by a bizarre and deeply unsettling physical transformation that defies all logic. Her only hope for a cure arrives in the form of an alien entity resembling a space chicken. This peculiar extraterrestrial visitor offers Ren a deal to reverse the unwanted changes and restore her human body to its original state. However, this assistance comes with a strict condition that pulls her far beyond the boundaries of her normal life. To earn her way back to normalcy, Ren must agree to help track down a dangerous fugitive who has fled across the galaxy. Thrust into an unexpected intergalactic manhunt, the young girl must navigate a surreal cosmic conflict while desperately seeking a way to undo the strange alterations forced upon her.
