This Platform features an animated band in a Classroom stage. Their animations loop indefinitely and the ceiling lights in the classroom are compatible with Beat Saber Lights. This platform can be used with any other Beat Saber Environment since it doesn't replace the default platform.
This platform is called "Lost One's Classroom" because it was used in the "Lost One no Goukoku" Music Video: https://youtu.be/ofyRaMcKFPQ
