Hilarious how all these years later I'm randomly listening to anime intros on YouTube and stop in shock... "WAIT, I KNOW THIS SONG, WHERE HAVE I HEARD THIS BEFORE???". When I first saw this video WAY back in the day, nobody knew what the song was nor did they comment it so I gave up. Now I randomly come across it and somehow remember this was the video I heard it from.
