Tanis, a prodigious child, is the youngest offspring of two eccentric scientists. Their family has lived apart from ordinary society on a secluded island, where the pair carried out experiments on Tanis' brothers and sisters that granted them extraordinary powers. The experiment ceased when authorities discovered the work and detained the parents. Government agents relocated Tanis and his four siblings to a more populous island. Snow, a canine‑human hybrid; Ashise, a botanical‑human fusion; Aisley, a arachnid‑human blend; and Suishi, who can read minds. As the sole sibling untouched by genetic alteration, Tanis shoulders the task of guiding his family into normalcy while masking their unique traits in a world that fears their differences.
