Summary
The Medaka Mermaid Quintuplets are five miniature mermaids and friends of Keimi. The sisters are named Ichika, Nika, Sanka, Yonka, and Yonka Two. Yonka Two is characterized by her dark brown hair, a black top, a tail with yellow stripes, and a hat featuring jaguar prints. The group shares a distinctive conversational routine where Ichika makes a statement, Nika repeats it with excitement, Sanka negates it, Yonka questions it, and Yonka Two dismisses its relevance. Despite their unique speech pattern, they are cheerful, friendly, and almost always stay together. They first appeared in Chapter 608 and Episode 527.
