Chom-P's most notable work, and also his first collaboration with Tamura Hiro. It only took the song four days to reach Nico Hall of Fame (exceeding 100,000 views). A "short" version was uploaded three months after the full version was uploaded, the short version is Chom-P's entry for the game -Project DIVA- Arcade. It tells of a story of a girl (Rin) who wants to "take off her panties" as a symbol of wanting "freedom"; wanting to not be nagged by adults. Later on she realized that she can choose whether to be mature or childish.
