CHUNITHM:LUMINOUS PLUS/CAVE of RVESE

CAVE OF RVESE is a hidden unlock system in CHUNITHM LUMINOUS PLUS. Unlike previous hidden unlocks like MISSION in progress or 1UM1N0U5 ep.111, the secrets are not fully discoverable from the beginning, instead being tied to songs added over the course of CHUNITHM LUMINOUS PLUS.
