The Sisters (one is Karasu who is armed with the kusarigama and the other is Washi whom wield two katanas) 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.
Karasu and Washi, alongside Satiaru, was born as daughters of Raiden. They honed their skills together as Heaven's most fearsome assassins.
In Kubo and the Two Strings
The Sisters found Kubo where he unknowingly stayed out of the night after an unsuccessful attempt to contact his supposedly deceased father. They sadistically intimidate him as they asked him to join them. Both sisters then conjures darkness in form of mass of black smoke full of tentacles that tried to reach the boy, even goes so far to have conjured darkness destroyed and rammed everything that stood on their path. When Kubo was cornered, Satiaru interfered by dispelled the darkness away, before enchanted the crest on Kubo’s robe that sprouted wings that took the boy away, but not before asked him to find the suit of armor needed to defeat Moon King. Afterwards, the Sisters fought Satiaru and seemingly destroyed each other.
Skirmish on Kubo’s Ship
After realized that Kubo is searching for mystic armor needed to defeat Raiden, The Sisters immediately make haste for him. One of them, Karasu, fought Monkey as he and Beetle goes for the Armor. As they fight, the Sister expresses their fury and disgust with their sister’s love toward Hanzo. In spite of her immense skills, she proved to be a match for the Monkey. The fight briefly interrupted by the Beetle whom returned just for fish that Kubo previously shot with an arrow. Karasu goes to attack Beetle, but Monkey interrupted by ensnare her neck with her own kusarigama’s chain.
The battle destroyed much part of the ship, and as Karasu dismissed love as a weakness, she prevented Monkey to get her hands on Unbreakable Sword, only for Monkey reach it in time and deliver a fatal blow on her, killing her and left the only one Sister remains.
Battle in Hanzo’s Fortress
The last sister, Washi, showed up where she had the heroes on their mercy, and in disgust, revealed that Beetle actually Hanzo’s cursed form that she and Moon King put on him for her love with his daughter. As she tried to took Kubo’s last eye, Kubo smack her head enough so Monkey, whom has revealed to be Satiaru's incarnated form, attack her. The fight ensued with Monkey overpowered by Washi and mortally wounded her, only for Beetle delivered a powerful blow on her. This however, not stopped Washi whom mortally wounded Beetle and goes after the heroes again. Before Washi delivered a fatal blow on Monkey, Kubo uses his powers to unleash a powerful mystic wave, killed her.
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 distinguished one of them with another is their respective weapon of choice: One sister holds a katana and the other a chain scythe (kusarigama).
What made sisters are frightening advesaries that Kubo ever faced was both their ability to speak in unison or finished each others' sentences and psychopathic, tenacious, and fierce personalities they shared in common. Both Karasu and Washi were not just the textbook definition of a persistent stalker, but also cold, cruel, calculating, dark, creepy, and homicidal to the core that they take pleasure in ending anyone that is foolish enough to interfere with their resolution to catch Kubo, even innocent bystanders whom not know anything. The Sisters are shown to be quite sadistic as well, enjoying the suffering and sorrow of others and laughing uncontrollably when they saw how frightened Kubo was in their presence during their first confrontation. They hate and despise anything that is pure or light, preferring to embrace the darkness of night as an old friend.
Karasu and Washi are also vengeful and embittered killers. Like their father Moon King, The Sister used to look up on their sibling Satiaru whom used to be best assassins compared to them. When they found that Satiaru fall in love with Hanzo and married him, they not surprisingly hurt with the betrayal so much that they eventually despised her and had no qualm in killing her. In their separated confrontation with the heroes that led to their deaths, they expresses their anger and pain as they tried kill Kubo, Monkey(Satiaru's animated monkey amulet form) and Beetle (humanoid being trapped within beetle-like body whom later revealed to be Hanzo's cursed self).
