Niuniu, who comes from Tianyan's planet, is his classmate and aspires to be a superhero. He is intrigued by the idea of death but has less magical prowess than Tianyan. Despite this, he dreams of becoming a popular "superman" on Earth in the year of the ox. Niuniu's stubbornness and individual perspective often lead to conflicts and strange events involving him, super "Kangtou," and Xiang Ling.
