Could be Osamu Tanabe because he is the only remaining in credit

Source: a video portfolio with the cuts he did: http://www.studiomir.co.kr/en/archives/artist/jaemyung-yoo-2

Odd. But it is from MIR's website, so I think it is reliable.
I've seen the video but checking on many other sources to see if he's credited for the actual animation hasn't exactly proved fruitful. All i ever find is him credited for stuff like timing and animation direction. I have no doubt its his work as its consistent with his work on Wonderful Days but just putting that out there.
 
The first couple of seconds feel like Imaishi or Amemiya.
 
DEEN ruining Log Horizon hard I see.
 
Confirmed by the second BD booklet
 
Right, my first upload so delete&slap me silly if I did something wrong.
