Tanis, the youngest son of two crazy scientists, is a kid genius. His family has spent their lives separated from civilization, living on an isolated island where the pair performs experiments on Tanis' siblings, resulting in them obtaining extraordinary talents. This action, however, is halted when they are apprehended and arrested. Tanis is taken to a more populous island by government authorities, along with his four siblings: Snow, a dog-human hybrid; Ashise, a plant-human hybrid; Aisley, a spider-human hybrid; and Suishi, a mind-reader. Tanis takes on the duty of adjusting his siblings to society as the only one who has not been genetically changed, all while attempting to disguise their distinguishing qualities.
