Half of this is blatantly reused sprites and CGs from Tsukihime and Kagetsu Tohya, and it looks like it was made in Sony Vegas. Yet it's still oozing and overflowing with passion. They just don't make 'em like they used to.
I always knew that the composer had to provide the vocals for the opening, but learning decades later that said composer were Raito, the guy who has been and still is doing all of French Bread's music to this very day from the humble Glove on Fight all the way to Under Night In-birth and Type Lumina really emphasizes how amazing this guy is. His style usually swings back and forth between atmospheric and rocking tracks, which makes it hard to compare many of his pieces to other fighting game composers, but I'd still say that he's the only fighting game composer that could challenge Daisuke Ishiwatari for the title of most consistently amazing long-time fighting game music composer in my eyes. If UNI 2's remixed themes are any indication, the man has yet to stop improving his craft.
