@@insaneabrokenheroofficial yeah, it was just a video created by someone in japan for nico nico douga back in the early 2010s based on an obscure playstation 1 horror game. the clips of yu, yosuke and chie are actually traced from the opening of an anime show called earth girl arjuna
I very doubt about that video, there is no OST from P4 and ATLUS licensed music only once, in western version of DDS, so that video is probably fanmade
