after looking at this more closely, I dont think this is arai. the triangular debris at the beginning and the smoke plume shapes having the shading being at the bottom are iso-adacent, and Ranke's ears in the gorilla form as seen at 0:15 are Okiura type and i havent seen arai do things like that before.

iirc the tag was from an old MAD with no source, so you're probably right
