storyboarded by Atsushi Wakabayashi (under the PN 百ノつぶて)

All the spins and flips towards the end are extremely characteristic of him

As for the animator responsible, there is smth odd about this scene since Seiko Asai's part is confirmed elsewhere and nobody else would really animate action -- maybe Wakabayshi stepped in to fix the flips in the last two cuts himself? Or Asai just did two different scenes
