In this sci-fi/fantasy survival thriller, the dangerous and deadly realm of the Otherside—where urban legends roam—calls to two women, both in search of something. As they set out to sate their curiosity and explore this other world, will the most earth-shattering thing they discover on the Otherside be their feelings for each other? Sorawo and Toriko head deep into the Otherside to save some old friends—none other than the American marines who wandered into Kisaragi Station and got stuck in what they call the Beyond! The pair, dubbed "the girls" by the Okinawa base troops, hatch a plan to rescue the trapped soldiers. Will everyone make it out alive and unscathed? Or will the Otherside claim new victims along the way?
