See, this is what I hate about the episode. If They included "???%" then people wouldn't be so confused that everyone thinks it's "angry mob". The "???%" sign and "I knew... I would be needed..." message panel in the manga is important and also builds up the hype more him being in that form/entity taking over in the forest. I think it would have been perfect if they added that.
I really enjoyed the art style change, I'm not sure what it was but it looked so different the entire episode. Personally to me the art looked like a mix of FLCL or Space Dandy? The soft pastel colours I suppose? Maybe it's just me who noticed it. Though Tome's character design really fitted so well, honestly so many good frames with her in that could make good pfps, was never personally a fan of how she looked in the anime before.
One minor criticism I did notice alot of missing faces in some shots, usually it wouldn't bother me if it was once or twice but I did notice it quite too often early on in the episode.
