Yeah, fanservice can go wrong, as you've said. Fortunately, this was done very well. It gives me a "we know you guys exist and we thank you for being a part of it" kind of vibe. I may be wrong, but that's what I get from it. I do love the show, I love all of the talent behind the show, and as someone who wants to get into the voice acting business, it's very interesting to follow.
