For as long as anyone knows, beings called "Puppets" have been an invisible part of our world. They operate in service of a force unknown, quietly manipulating the course of history.
Hajiro Mina is an ordinary high-school girl and the protagonist of this story. One day, she has a chance encounter with one of these Puppets, setting her on a trajectory to meet three girls—and ultimately changing her life forever.
The girls belong to an organization that specializes in the extermination of Puppets. They have been granted extraordinary powers by a doll named Ruka, and their job is to locate and eradicate the inhuman enemies lurking in the crowds.
As Mina finds herself entangled in this supernatural conflict, it becomes clearer with each passing day that there are greater forces at play.
Fifteen years old, a first-year high-school student, and the story’s protagonist.
Mina is an ordinary girl attending a public school. Her father passed away when she was a child, and she was raised by her mother. Shortly after entering elementary school, she began helping her mother prepare food and do chores.
At a glance, Mina seems frail and delicate, stimulating the protective instincts of those around her, but at her core is an intractable spirit of innocence. This pureheartedness inspires trust in people she interacts with.
Mina has taken to visiting a doll gallery most days on her way home from school, and it is there she meets the Eidos called Ruka. Inadvertently resonating with Ruka, Mina becomes her fourth emissary and finds herself entangled in a conflict with the Puppets.
Twenty-one years old, owner of the best high-class Chinese restaurant in Chinatown, and member of a massive Chinese business conglomerate.
She is the only daughter of Yang Li-Fang (a.k.a. Grandma), owner and curator of the doll gallery Pygmalion. Her mother taught her the truth about the world from a young age, but an event in their past damaged their relationship, and presently, they are on less-than-friendly terms. As a result, she sometimes has trouble keeping her emotions in check.
