remove implication atelier_sophie_2 -> atelier_sophie
create implication atelier_sophie_2 -> atelier_(series)
Unlike Atelier Ryza, Atelier Sophie isn't an umbrella tag for games that feature Sophie Neuenmuller, it's meant to be used only for the first game within the Atelier Mysterious subseries, so I'm not sure why this implication is here. From what I've observed, this isn't how sequel implications usually work on Danbooru (Pokemon BW2 does not imply Pokemon BW, the Ace Attorney games don't imply their prequels, and so on). I think this implication is unnecessary, since, aside from the two main characters, the cast is almost entirely different, so it's unlikely that you'd want to see art for both Sophie and Sophie 2 at once. It also would make more sense to group all four Mysterious games that take place in the same world (Sophie, Firis, Lydie&Sue, Sophie 2) together instead of just those two games, if there's a need for an umbrella tag after all.
