The Idol of the Season, Zero! Theme: The Four Seasons and Y2K, Preppy Look Description: To celebrate XPPen's 21st anniversary, Zero & Fenix, representing each season, have come together for a celebratory performance. Spring, which brings cuteness; summer, which carries a hot intensity; autumn, which has a chic mood; and winter, which exudes cool charm. They come together as a team and head to the venue (TOP TOY). Their managers, Null, are joining too!😊
