Haruka is busy working at the agency so she can't help the idols with the preparations for the Christmas Party held by Shining Agency. A lot of memories and information are revealed while Starish is preparing for the party. The story centers around the activities of Wakaba Kohashi, "a slightly out-of-tune super" daughter of a well-to-do family, and her friends. Wakaba (literally, "young leaves") looks like an elegant rich daughter, but she admires the trendy gyaru fashion subculture. There is also the pure, innocent, fairy-tale-like Moeko. Mao is capricious and behaves in her own way. Nao used to be an athletic type of girl, but now loves the boys-love genre.
