Intro
Guest has skipped grades to become the top S4 of the Wind Dance Class as a first-year middle schooler. Even before entering Four Star Academy, Guest was a famous figure in high demand for TV shows, music programs, dramas, and movies. Before the new semester began, Four Star Academy lacked a student suitable to take over Yuzu Nikaido's position as the head of the Wind Dance Class. Thanks to a debut stage held right after enrollment and a successful pre-enrollment career, Guest has officially become a member of the S4.
