After surviving the Titan world and helping its people break free from the chains of destiny, Ryo Smith has finally accepted his new identity as Ultraman Aeon-a Giant born from Tiga's inherited light, accepted darkness, and an unwritten future.
But his journey is far from over.
An Ultra Sign from the original Ultraman Tiga guides Ryo toward another universe: a society where nearly everyone possesses a superhuman ability called a Quirk and professional heroes have become symbols of justice.
Ryo arrives at the Unforeseen Simulation Joint just as Class 1-A begins rescue training with Eraser Head and Thirteen. Moments later, the League of Villains invades. The students are scattered, the teachers are overwhelmed, and a bioengineered monster called Nomu prepares to kill the Symbol of Peace.
To the villains, people are disposable tools.
To hero society, powerful children are the future.
But Ryo has already witnessed what happens when frightened children inherit the wars, expectations, and mistakes of adults.
Standing beside Izuku Midoriya and Class 1-A, Ryo must use everything he learned from Eren, Mikasa, Armin, Reiner, Ymir, and the people beyond the walls. Yet his arrival changes more than the U.S.J. attack. All Might's enemies sense a power beyond Quirks, U.A. begins questioning the stranger who can become a Giant, and Tiga's warning reveals that something far greater is approaching.
In a world filled with heroes, Ryo must prove that true heroism is not determined by power, rankings, or destiny.
It is determined by what someone chooses to do when another person needs saving.
A new light has entered the age of heroes.
