Going through old folders and found this gem.
There is an aragami in the God Eater series known as a Chi-you
They're extra set of arms (the big ones) reminded me of those dance wings that are usually used for belly dancing.
Ever since then I can't get the image of a Chi-you doing the tango or some fast pace dance out of my head.
Edited: Just realized that the Chi-you doesn't unfold it's arms for anything, except for that one death animation... need to fix that...
The Chi-you belongs to the God Eater series
Hand drawn who knows how long ago.
