Strings Dolls

Shiro and his younger sister, Koyori, discover a game that lets them control anyone visible through a camera as if they were a puppet. After an accident leaves Koyori permanently unable to walk, they find that the game can temporarily restore her ability to move, bringing them joy. But other players put the power to darker uses. Among them is Miyabi, a mysterious player apparently using the game to kill fellow users. Shiro sets out to uncover who is behind the game and find Miyabi before it is too late.
