If you're expecting a faithful adaptation from the original source, then don't get your hopes up. The studio has already made noticeable changes, including the introduction of an anime-original character in the very first episode. On the other hand, if you're unfamiliar with the original source and are simply here for cute cat girls with a bit of fan service in it, you've come to the right place. That said, anime-only viewers may find certain parts of the episode a bit confusing due to the lack of context. Overall, I think the premiere is fine. While the art isn't particularly outstanding, it doesn't look out of place either, especially from the perspective of someone who has played the original source.
