Why can't hippo and Yuri stay together in merimaid melody?

Answer 1

In "Mermaid Melody," Hippo and Yuri cannot stay together primarily due to the differences in their worlds and the responsibilities they each have. Hippo is a mermaid, while Yuri is a human, which creates an inherent barrier to their relationship. Additionally, the narrative focuses on the challenges of love across different realms and the need for characters to fulfill their destinies, making it difficult for them to remain together. Their separation highlights the themes of sacrifice and the struggles of love in the series.
