Smooth Transisting Animation

This is the current opening sequence to an Anime I watch. Usually the shows has some cheesy opening with some basic animation, but the opening here is like movie quality for anime. The animation is just so smooth and everything. Personally, this is the best opening in both series of the show. This is the 6th opening of the long running series. Also, the dark contrasting with minor fully, vivid, and bright colors was very interesting in the beginning. As well as the dark style of animation halfway through the video. The manga started back in 1999 and it's 10th birthday already passed. It is very popular all over the world and is still continuing to this day. Hopefully the opening's animation will be used in the show because it has been getting some choppy animation a lot recently.
