Mou ikkai! (Version 2)
And here is a second version, with dancing Marisa and Sakuya. The kotatsu was taken away to make room. Unfortunately, the looping isn’t much better either. When I change things, it either loops kinda okay (but not that really that great) and is really desynchronized, or it doesn’t loop so well but the synchronization is good. I chose the latter.
First version here.
