Tri Realm: Reborn in Iron
Akio Tanaka, a 12-year-old boy from Japan, leads an ordinary life until an unexpected world war devastates his home. When a bomb from Russia destroys his family right before his eyes, his life is shattered. A Russian agent, witnessing Akio’s loss, takes him under his wing, driven by pity for the innocent victims of war. Akio, filled with grief and rage, swears revenge against the world’s power holders who perpetuate these wars. He trains under the Russian military, growing into a ruthless and feared agent, carrying out covert missions until he succeeds in killing every world leader in a devastating strike.
But just as he completes his mission, a tragic turn of fate strikes—his helicopter is shot down, killing him.
In his next life, Akio is reincarnated in a world filled with magic and constant warfare. He retains the memories of his past life, including his goal of eliminating those in power. This new world has its own battles—demon lords, factions, and endless conflict—but Akio is focused on what he sees as the root cause of his suffering: the powerful individuals who continue to incite wars.
As Akio matures into a young man, he works the land of his adopted family, learning the ways of this new world. However, fate is unkind once again as his village is invaded, and his parents are killed. Filled with sorrow and confusion, Akio questions whether he is cursed. He forms a bond with a new friend at the orphanage who saves him from despair, encouraging him to keep fighting for his own future.
At age 7, Akio begins magical training, as children in this world gain magical powers at this age. After witnessing the brutal military training of young soldiers, he and his new friend join a dangerous project meant to train elite soldiers—children who endure extreme, life-threatening tests. Only a handful survive, and Akio is among the survivors, gaining even more control over his abilities. His friendship with those who endured the training together grows into a bond of fierce loyalty, and they become feared generals in the military.
However, as the world around him becomes more fractured, and as the influence of the Demon Lord grows, Akio must confront a new challenge: how to navigate his power, the pressure from his allies to dominate the world, and the endless battles that stand in his way.
When Akio finally faces the Demon Lord, he kills him easily, but before dying, the Demon Lord reveals a shocking truth: Akio’s destiny is tied to a greater force. Using a mysterious orb, the Demon Lord triggers a powerful event, sending Akio to yet another world.
In his new life, Akio is reincarnated as the son of the Demon Lord, destined to inherit the throne. He witnesses his parents’ deaths at the hands of a hero, and he becomes the new Demon Lord, inheriting his parents’ power. But his reign is fraught with challenges, both external and internal. Akio is a reluctant ruler, unwilling to attack humanity, but pressure from his generals and the threat of human invasions push him toward war. Akio struggles to balance his desire for peace with the brutal reality of war, and his identity as the "Demon Lord of Tyranny" takes root.
As Akio battles both external enemies and the pressure from within, he faces the ultimate question: Can he break free from the cycle of violence that has defined his existence, or will he fall into the same patterns of power and destruction that have plagued him across worlds?
