The Sisters, are the secondary antagonists in the film, "Kubo and the Two Strings".

These spectral twins are both the Moon King’s daughters and his most powerful and ruthless assassins. They are the sisters of Kubo's mother but have never treated family above themselves, only when obeying their father. Identical in voice and appearance down to their chilling Noh masks painted with a frozen smile, the Sisters are in charge of dispelling their father’s worries and hunting down his enemies. They do not need to eat, nor to sleep, and they shall not let anything stand in the way of them capturing Kubo and fulfilling the wishes of their father.
