An ending that barely feels like an ending. This episode leaves behind so many unanswered questions that you'll probably end up wanting to check out the original source just to find out what happens next. And trust me, the story is worth it. The animation is pretty much close in the first episode, it's not surprising that they brought back this style for the final episode. There are plenty of callbacks to past episodes and characters, while the return of the first OP adds a nice nostalgic feeling. However, despite being the finale, it's clear that the story is nowhere near finished.
