About

Shortly before the zombie outbreak, Teto, a researcher at a certain laboratory, was working on cloning technology alongside her close colleague Miku. Despite Teto appearing indifferent to Miku's constant clinging, Miku would glare at other researchers who badmouthed Teto. Teto, in turn, never pushed Miku away and would rest her hand on Miku's head. Teto even kept a locket with a photo of a flustered Teto being celebrated by Miku with a cake—suggesting that while she didn't express it, she held deep affection for Miku. Other researchers criticized them, calling their work a pipe dream and telling them to study something useful, but Teto ignored them. Eventually, she succeeded in everything from gene copying to clone production. At that point, 128 Teto clones were produced (or prepared for production). Just before the outbreak, Miku was transferred to a neighboring lab for unknown reasons. Soon after, the zombie apocalypse hit, forcing the two into an indefinite separation. Unable to endure this, Teto armed herself with a shotgun and a baseball bat. Driven by the single-minded determination to find even the last trace of Miku, she began a journey, using her cloning technology to sequentially deploy clones as she searched for her friend.
