In Last Ranker warriors are ranked by how they perform in battle by a combat organization called Bazalta, which is headquartered in the city of Ghandoar. The protagonist of the game is a man named Zig who is part of a group of wanderers called Cantalera and decides to leave his group and head to Ghandoar, join Bazalta, and make his way to the top.

In combat the player will only use Zig to fight in real-time. However, they will not have direct control over Zig's movement. As attacks are chosen from the menu they use up SP and the gauge takes a few seconds to recharge when depleted.
