Synopsis
After a plant-eating dinosaur discovers a lost egg, she brings it to her nest. When a carnivorous dinosaur hatches from it, she decides to keep him, naming him Heart and raising him alongside her own young. Heart later struggles with the vegetarian diet enforced on him and eventually runs away in shame upon realizing his true need for meat. Growing into a feared predator, Heart encounters a situation mirroring his own past when he finds an egg from a species he would normally hunt. When the baby emerges, Heart comments that it looks delicious, which the herbivore mistakes for its name: Umasou. Unable to eat a creature that views him as a parent, Heart reluctantly becomes its guardian. Just as his mother once did, Heart must now raise a child deemed unacceptable by society, navigating a harsh world and the inherent conflict between predator and prey.
