This is the "fixed" version of Niho's famous sequence in episode 7.

Fixed version is boring, specially the beginning.
I liked it more when it looks like something made in an animation class.

Sometimes I feel the original version was too rushed to make it into the episode.

In a way it was almost like inbetweened and composited roughs, well very personal roughs but its nice to also have the corrected version, since this is an extreme example of after airing corrections, it is almost like a documented but refined process of the stages of animation.
