Summary
The Medaka Mermaid Quintuplets are a group of five petite mermaid friends of Keimi, consisting of Ichika, Nika, Sanka, Yonka, and Yonka Two. Nika is distinguished by her blond hair and a red-striped tail, wearing a red top and a hat that matches her tail. The sisters share a distinctive conversational routine where each contributes a specific variation to a statement made by Ichika. After Ichika makes an initial claim, Nika repeats it with excitement, Sanka states the opposite, Yonka questions the validity, and Yonka Two dismisses the importance of the topic. They are generally cheerful, friendly, and prefer to stay in close proximity. They first appeared in Chapter 608 and Episode 527.
