Rina Tennoji, known for her unique communication style using a digital board, and Emma Verde, a transfer student with a warm and caring personality, add further depth to the ensemble. Kanata Konoe, a sleepy yet talented idol, and her younger sister, Haruka, who idolizes the club members, round out the cast.

The manga emphasizes lighthearted moments, such as the characters’ attempts to balance their idol responsibilities with schoolwork, their playful rivalries, and their efforts to support one another. The humor often arises from exaggerated situations, misunderstandings, and the contrast between the characters’ personalities. While the series does not follow a continuous plot, it provides a charming and comedic glimpse into the lives of the Nijigasaki idols, showcasing their camaraderie and individual growth in a school setting.
