Last Ranker: Be the Last One

A combat organization called Bazalta ranks its fighters, known as Rankers, based on their strength, with higher ranks offering greater rewards and influence. Zig, a boy from the tribe Cantalera, where combat is forbidden, begins training in secret after his father is killed by monsters. Despite his efforts, he fails to protect his people from the creatures, prompting him to leave and pursue a path in Bazalta, aiming to rise to the top.
