Well, okay. Protip, if you're looking at art and wondering if it's official or not, if it's been tagged 野生の公式 it's fanart.
Apparently that's pixiv/jp community's tag for fanart that imitates official art styles
brought to you by: me trying to figure out if this saved mmz art was fanart or not
because it looked very convincing and yet was missing all the typical markers of toru nakayama's art
well, not all. a few markers
i couldn't find it on pixiv either so i was so baffled
i found it posted on nico nico douga...
