Plunderer is a Japanese manga series written and illustrated by Suu Minazuki. It began serialization in Kadokawa Shoten’s Monthly Shōnen Ace magazine on December 26, 2014. The series is licensed by Yen Press. An anime television series adaptation by Geek Toys premiered on January 8, 2020.
Set in a post-apocalyptic world dominated by numbers, every human being has their worth measured by a special ‘Count’ imprinted somewhere on their bodies, which defines any number related to an important aspect of their lives. However, if this Count decreases to 0, the person will be dragged down into “the abyss”, and is said to be dead for all eternity.
For young Hina, her Count corresponds to how many hundreds of kilometres she has walked. Ever since her mother was dragged into the abyss, she has been searching for the Legendary Ace from her mother’s last wish for the last five years. Hina’s gruelling journey takes a sudden turn when she meets a strange masked knight known as Licht Bach with a negative-numbered Count.
