Zhang Fei from Wangyu Village is a "freak" who was born from fish eggs and has scales all over her body. She is often discriminated against. During a big tide, he rescued the weak Shark Girl, who claimed to be his bride and told him that he had the mission to protect the sea and prevent disasters. Zhang Fei awakened her power and saved the villagers, but Shark Girl left without her skin, agreeing to meet again when he awakened his power, and his journey of fantasy guardianship began.
