In an academy full of reincarnators, the only exception challenges the top.
About
-Synopsis-
In this world, "Inheritors" who possess the memories and powers of their past lives are treated as special beings. Heroes, Demon Kings, Sword Saints, Saints, Sages—. Those who have inherited the power of past heroes compete for rank at the Inheritor Training Institution, "Inheritance Academy." Rank is absolute. The higher the rank, the more honor and power one is granted, with a future guaranteed by nations and corporations. Guest, who enrolled in such an academy, is not an Inheritor. They were just an ordinary person with no memories or powers from a past life. However, the aptitude test at the time of enrollment produced a result that shook the entire academy.
"Unmeasurable"
"EX Rank"
An abnormal result, the first since the academy's founding. Rank 1 Inheritor of the Hero King, Rank 2 Inheritor of the Demon King, Rank 3 Inheritor of the Saint, and Rank 4 Inheritor of the Sword Saint begin to take notice of Guest. Guest denies it repeatedly.
"I'm telling you, I'm really not a reincarnator."
But no one believes them. Thus, Guest is dragged into the academy's ranking battles, ruin explorations, team battles, and inter-school competitions. In a world where past heroes compete, the battle of the only exception, Guest, begins.

Intro
The day of the entrance ceremony. The world's premier Inheritor training institution—Inheritance Academy. In this place where "Inheritors" who carry the powers of past heroes like the Hero, Demon King, Sword Saint, and Saint gather, a single boy stood before the measurement device.
"Next, Guest." Prompted by the teacher's voice, Guest touches the crystal. The surrounding students watched with little interest. A commoner who isn't an Inheritor. There was no reason to expect anything.
But in the next moment— The measurement device emits a violent light. 'Measuring...' 'Analyzing...' 'Error' 'Unmeasurable' 'EX Rank' The hall fell silent. Even the teachers were at a loss for words. It was a result that had never been recorded since the academy's founding.
The first to speak up was the academy's Rank 1, Reina Amagi. Her blue eyes stared straight at Guest.
