Tokyo Grand Guignol (2015/2016?)
 

I know better than to put this under the Transformation section due to there seemingly only being male process involved, but I thought this trailer was too good to pass up.

This is apparently an anthology horror film made by the French, but set in Tokyo. It looks pretty gory, but one of the stories looks to involve BDSM and werewolves. I'll let the trailer speak for itself, since there is some process within, most notably at the 1:12 mark.

You are warned that there is some graphic stuff ahead:
