I guess I was right the Satyrs are Uma Musume-esque Horse people...And some of them might have horns like from unicorns perhaps...? This is the original box set image that I was able to quickly find, so it looks like them being in Black and White might also have to do with them being Satyrs...? Perhaps???? idk.

I am grasping at straws lol. For all I know Satyrs look completely different or something XD I wonder if who has horns on this box set matches or something, like if the characters have powers? I have never seen DN Angel before so idk.
