I was looking at the list and saw that Yuuki Terumi was listed having Etheral manipulation but I can't think of anytime in BlazBlue where any of the casts has shown this ability. I think whoever put him there confused seithr for Ether. What do you guys think? Also on that topic, what would seithr even be? It was stated that seithr are particles that are the primordial state of all things and that everything is made out of seithr. Wouldn't that make it primordial particles?
