I think the Anime classes don't get it because everything is just bought with points, while the DnD classes are broken down to fit a point-based system. The only thing that doesn't seem to transfer over is the background abilities. Backgrounds otherwise are 4 points worth of proficiencies. I only that at this point is to give the Anime classes access to a background ability at no cost, since they don't have a corresponding point cost in the A5E book. The proficiencies tied to an Anime class we've already bought.
