In the world of Varcita, there is a continent named Meruem which is known as "the continent of the kings". The continent is split into five kingdoms, each ruled by "kings", and each king rules with an iron fist and makes life on Meruem almost unbearable.
Follow Mirah, a street child, as he begins his journey in the real world: from mundane activities such as attending classes and meditating to life-threatening adventures like fighting in a tournament and stopping a genocide. Along the way, he picks up some friends and allies like Lucas, a coward, and Kilyua, a mysterious transfer student.
However, behind the scenes many mysteries arise. Who are Mirah's parents? What is the ancient Yuuos bloodline magic? Who really is Hiramal Kio? Many questions, very few answers.
