Since Shin Itagaki posted information about this opening on his style.fm column some time ago and I’m quite fond of it too, I thought that I could as well summarize and visualize his statements here. I love the energetic and lively nature of this opening which comes about thanks to the fun movements the animators created, but have a look yourself:
The opening was directed and storyboarded by Shin Itagaki (Devil May Cry, Black Cat, Basquash!) and the animation was supervised by Haruka Tanaka.
