After an explosion at a mysterious lab on the Galápagos Islands, evolution goes out of control, creating monstrous mixtures of humans and plants or animals. Young Gaku has merged with the plant monster Anemone, and the more time they spend together, the more they begin to affect each other. But Gaku’s not alone—he finds others who have merged with plants and animals and have new, fantastic powers too. The danger escalates as they get closer to finding out exactly what happened at the lab in this final volume!
