G-OGRAPHY: a southeast asian lady travels...

Discovered this trailer while I was searching for movies to watch on Netflix. I'm deliberating on whether to watch it because I am really not a big fan of gore. Although I love anything Japanese or Martial Arts.

The movie is about a Japanese school girl avenging her brother's death. She lost an arm to a yakuza ninja family- the very clan that killed her brother. She survives their attack after which a bunch of mechanics help her get revenge by making her a prosthetic machine gun. Wow...I am not surprised that people can can come up with this nowadays but does this really happen in real life? I wonder if there is some parellel universe where this situation exists...
