The IB Year 2 rock band "Papillon" performed on the outdoor stage at the school festival on September 20. The band consists of six students from the IB course, with each member playing drums, keyboard, guitar, bass, and vocals. As part of their IB CAS activities, the students have been consistently practicing and performing.

During the performance, they played three rock songs in both Japanese and English. Their full-fledged performance, which included guitar and drum solos, thrilled their classmates, parents, and faculty who had gathered to watch.
