part of this is Tsumagari(before Fujii)

~1:45s-end: Daisuke Tsumagari and then his part continues for the first cut in post #45719
the rest is mostly Yamashita but there's so many cuts in this upload it's hard to say he did everything hence artist_unknown

edit: worth noting pretty much the entire thing is heavily corrected by Yamashita as well

edit2: Nvm Watanabe's part isn't confirmed or known, just that it's in here somewhere?

Were Watanabe's and Tsumagari's parts confirmed?

Blue confirms stuff by talking to the staff so it's safe to assume, yes.

It's so confusing where Yamashita's part in this post could be:
The running part at the beginning doesn't seems like him
0:40-1:03 Not Yamashita, even he couldn't correct most of it.
1:03-1:15 maybe NC work, some parts are similar to Matsumoto or Fujisawa style in drawing.
If Yamashita done key animation it should be something in 1:16-1:31, but even this could be a heavy correction (most likely it is a redrawing with some key animation).

I mean, just like all his episodes he re-draws everything but the L/O timing isn't always going to be completely fixed so you have stuff that half resembles him and half doesn't

28-38 straight up looks like his KA, also nothing here is Fujisawa or Norio, the latter did work on the episode after though.
