The Sisters

The Sisters are the wicked twin aunts of Kubo and the secondary antagonists, along with their father, The Moon King, in the 2016 stop-motion movie Kubo and the Two Strings. They are both voiced by the Academy Award nominated actress Rooney Mara in her first villainous role.

They are both wearing kabuki masks to hide their identities, straw hats and only sister of Kubo's mother. They were sent to kill their sister for betraying their families and to blind Kubo's humanity to live with their father. They first appear, chasing Kubo until his mother rescues him and sacrifice her life for him.

Characteristics
Both sisters wear wide straw hats with disturbing noh masks covering their true faces. Under their feathery cape (which gave illusion of possessing crow wings), they wore dark black body armour. They also have jet black hair that tied into a ponytail.

The only thing that distinguised one of them with another is their respective weapon of choice: One sister holds a katana and the other a chain scythe(kusarigama).

Trivia

 * The Sisters' appearance may referenced from Tomoe Gozen, a prominent warrior in Feudal Japan whom had a face claimed to be as beautiful as porcelain.
 * The jet black feathered cape sported by the two Sisters included 861 laser-etched feathers, each uniquely sized and shaped. This explained how their capes gave illusion of raven cloak/wings.
