After stumbling upon the journal of a former prisoner, Leon and Doudou glean some clues about the location of the mysterious TORATSUGUMI. Now, they set their sights on a place called Sado-a place that seems to call up distant memories and complicated emotions in Tsugumi.  As Tsugumi wrestles with her past, she comes under attack by a swarm of flying monkeys. A hulking, female “clothed thing”-the same one that Leon previously fought and nearly blinded-drives the assailants away, but is she there to save Tsugumi...or to exact revenge?
