That's just a fan-made PV. Fan-made PVs, I believe, were pretty popular back in the day 2008-2009ish since most songs at the time just had a simple picture for the song so people wanted to express their intrepretation (ex: common songs like World is Mine, Kokoro, Servant/Daughter of Evil). Nowadays, there are often collaborations with illustrators or the producer can draw for themselves.
