Fuujin Year 130 (Medieval times when magic and gods were of great importance). Two years ago, the great war in the "Old Fuujin Continent" was controlled by the "Zenon Country" who possessed great power. In Randia, a small country to the south, the young prince Alfred is attacked by an assassin but gets saved by his friend Welles. The young prince was the last key to the revival of Randia... It was said that in legends the prince had the power to unleash the "Seal of Power" because of his blood relation. This brought fear upon the Zenon country and thus their attack. Welles was just another soldier, but he was also a close friend of Alfred's and they had been fighting together in the battlefield for a long time. That is why they're known as the "Galloping Winds" on the battlefield. And so, the two of them along with Welles' younger sister Teefa, are burdened with the fight for their country. Hearing that war is once again about to break out, the former loyal subject Rea also returns. As more and more people get involved in the war, the mystery of the seal unfolds... To reveal the "Blood Relation of the Prince"...

Nine regular humans from different parts of the world are abducted and transformed into cyborgs with astounding powers for the purpose of being used as weapons. The nine cyborgs rebel and start to fight against their creators in the name of justice and world peace. Decades later, the nine cyborgs seem to be untouched by time, but they live in a world where "justice" has as many nuances as the number of people living on the planet. What is their place in the world now? "In the beginning was the Voice, and the word was Him; and all obeyed His word in great awe. But those who dwelt upon the land, through vanity, cunning and greed, attempted to build a multitude of towers whose tops reached unto heaven, and accumulated great wealth on earth. Scattering across the land and laying it to waste, man turned a deaf ear to His Voice. So He gave unto man an opportunity to atone for his misdeeds; and flame and smoke and the roar of a lion descended upon earth; and shattered the many towers to dust...."

With Tomura Shigaraki at its helm, the former Liberation Army is now known as the Paranormal Liberation Front. This organized criminal group poses an immense threat to the Hero Association, not only because of its sheer size and strength, but also the overpowering quirks of Jin "Twice" Bubaigawara and Gigantomachia. As new intel from the covert hero Keigo "Hawks" Takami confirms that Shigaraki is nowhere to be seen, the Hero Association decides to strike the enemy headquarters with a surprise attack using the entirety of its assets—and the UA students find themselves on the battlefield once again. As the fight rages on, the unsuspecting villains must regroup and push back, but the brave heroes are determined to eradicate every last one of them.
