KATSEYE's debut EP, SIS (Soft Is Strong), reflects one of KATSEYE’s core beliefs – Soft Is Strong – and also nods to the sisterhood they’ve forged, despite coming from immensely different cultures. The six members of KATSEYE are: DANIELA (USA); LARA (USA); MANON (Switzerland); MEGAN (USA); SOPHIA (Philippines); and YOONCHAE (South Korea).
