Hirajima Natsumi, Okada Mei, Hazuki Himari, and Negishi Ai arrive at a luxurious beach house. Soon after arriving, they are informed that they will be competing in a series of challenges, the overall winner of which will be deemed the "center" of Merm4id. These challenges are interspersed with gravure-type segments that feature all four unit members. Challenges include guessing what sports each member played in school, cooking omurice, drawing logos from memory, guessing smoothie flavors, a capture-the-flag game involving inner tubes, and guessing items related to their D4DJ characters through touch.
Ai had not initially considered becoming an idol, but she changed her mind after discussing it with others. At the time, she was in high school and being scouted by Platinum Productions, and in 2009 she made her idol debut as leader of the flight attendant-themed group PASSPO☆. She created albums with the group until their disbandment in 2018.
