Centuries ago, humanity was driven nearly to extinction by colossal, humanoid monsters known as Titans, forcing the survivors to cower behind enormous concentric walls. The true horror of these giants lies in their consumption of human flesh, which seems motivated not by hunger but by pleasure. To ensure their survival, the remnants of humanity lived within these defensive barriers, enjoying a hundred years without a single Titan encounter. But that fragile peace is shattered when a Colossal Titan breaches the supposedly impregnable outer wall, reigniting the desperate fight for survival against the man-eating abominations. After suffering a devastating personal loss at the hands of the invading creatures, Eren Yeager dedicates his life to their eradication by joining the Survey Corps, an elite military unit that battles the merciless humanoids beyond the walls. Alongside his adopted sister Mikasa Ackerman and childhood friend Armin Arlert, Eren enters the brutal war against the Titans, racing to find a way to defeat them before the last walls fall.

An alchemy experiment gone horribly wrong shatters the lives of brothers Edward and Alphonse Elric. Defying the fundamental alchemical law that forbids human transmutation, they try to revive their deceased mother. The attempt backfires catastrophically: Alphonse loses his entire body, while Edward sacrifices a leg and then an arm to anchor his brother's soul to a massive suit of armor. Their neighbor Pinako Rockbell and her granddaughter Winry take them in. Winry, a gifted engineer specializing in biomechanics, crafts prosthetic limbs for Edward using "automail"—a durable, versatile metal found in robots and battle armor. After years of intense training, the Elric brothers embark on a mission to recover their original bodies by finding the Philosopher's Stone, a legendary gem capable of bypassing the law of Equivalent Exchange. As Edward earns fame as an alchemist and the moniker "Fullmetal," their quest pulls them into a far-reaching conspiracy that could determine the fate of the world.

For many generations, humanity has been pursued by enormous, enigmatic predators called the Titans. Three massive walls—Wall Maria, Rose, and Sheena—offered safety and tranquility for over a century. That calm was broken when the Colossal Titan and Armored Titan appeared and demolished the outermost wall, Wall Maria. Forced to withdraw behind Wall Rose, humanity waited anxiously for the Titans to strike again and ruin their final refuge. In Shingeki no Kyojin Season 2, Eren Yeager and his comrades from the 104th Training Corps have only recently started serving as full members of the Survey Corps. As they prepare to confront the Titans once more, their plans are interrupted by an invasion of Wall Rose—yet nothing is as straightforward as it appears, and additional enigmas come to light. While the Survey Corps races to protect the wall, they learn more about the attacking Titans and the hidden truths concerning their own ranks.

Humanity remains trapped behind the two surviving walls, still endangered by the Titans that steal their freedom. The fight to eliminate these monsters continues, but dangers come not only from the Titans outside the walls but also from the people inside them. Following his rescue from the Colossal Titan and Armored Titan, Eren Yaeger focuses on mastering his Titan shifting ability. Krista Lenz deals with the pain of losing a comrade, Captain Levi selects Eren along with his friends to be part of his new personal squad, and Commander Erwin Smith recovers from wounds he received. For a time, the soldiers seem to be doing well—until the government suddenly demands that Eren and Krista be handed over. The Survey Corps' recent victories have attracted unwanted notice, and a figure from Levi's past is dispatched to retrieve the two wanted individuals. Hunted by the authorities, Levi and his squad must avoid their enemies to protect Eren and Krista. Eren and his comrades fight not only for survival against the fearsome Titans but also against the menace of a far more cunning adversary: other humans.

In an effort to restore the fading hope of humanity, the Survey Corps launch an operation to reclaim Wall Maria, where the fight against the ruthless Titans resumes. Returning to the ruined Shiganshina District, once his childhood home, Eren Yeager and his comrades find the area strangely devoid of Titans. Even after sealing the outer gate, they face no opposition. The mission proceeds smoothly until Armin Arlert, deeply suspicious of the enemy's absence, notices troubling hints of a hidden trap. Shingeki no Kyojin Season 3 Part 2 follows Eren as he swears to reclaim everything that was taken from him. Alongside him, the Survey Corps push forward—through countless sacrifices—to carve a path to victory and unlock the secrets hidden in the Yeager family basement.

Gabi Braun and Falco Grice have dedicated their entire lives to training with the goal of inheriting one of the seven Titans controlled by Marley, aiming to assist their country in eliminating the Eldians on Paradis. Yet, just as their future seems secure, their tranquility is abruptly disrupted by the arrival of Eren Yeager and the surviving members of the Survey Corps. After finally accessing the Yeager family basement and uncovering the grim history behind the Titans, the Survey Corps has at last discovered the answers they had fought so hard to find. Now possessing the truth, the group heads out into the world beyond the walls. In Shingeki no Kyojin: The Final Season, two vastly different worlds clash as each side pursues its own objectives in the long-awaited conclusion to Paradis' struggle for freedom.

Young Thorfinn spent his childhood listening to tales told by old sailors who had crossed the ocean and arrived at the fabled land called Vinland. According to legend, it was a warm and fertile place where no one needed to fight—nothing like the frozen Icelandic village where he was born, and certainly nothing like the life he leads now as a mercenary. War has become his home. Though his father once told him, "You have no enemies. Nobody does. There is no one it is okay to hurt," as Thorfinn grew older, he came to believe that could not be further from the truth. The ongoing conflict between England and the Danes worsens every year. Death has become ordinary, and the Viking mercenaries revel in every moment of it. By allying with either side, they can drastically shift the balance of power, and the Vikings are eager to earn reputations for themselves while taking whatever spoils they can. Amid all this chaos, Thorfinn must pursue his revenge: to kill Askeladd, the man who murdered his father. For the Vikings, it seems, the only paradise is this relentless age of war and death.

After the heroes receive supplies and companions to train alongside, Naofumi begins his journey with the sole person who agrees to join him, Malty Melromarc. However, she soon betrays him, and he is wrongly accused of assaulting her. As a result, Naofumi faces severe discrimination and hatred from the people of Melromarc for a crime he never committed.

But as he goes on, the hardship of traveling alone becomes too great, so Naofumi purchases a dying demi-human slave named Raphtalia to join him. As the Waves draw closer to the kingdom, Naofumi and Raphtalia must battle to ensure the kingdom's survival and shield its people from their doomed destiny.

When he and his brother Alphonse attempt to bring their deceased mother back using the forbidden technique of human transmutation, Edward loses both his brother and two of his own limbs.

Together with his younger brother, he sets out in search of the Philosopher's Stone. This legendary artifact is said to greatly amplify an alchemist's power, allowing them to bypass alchemy's core principle: equivalent exchange, where one must sacrifice something of equal value to gain something. Edward intends to use the military's resources to locate the stone and restore his and Alphonse's bodies to their original state. But as the Elric brothers delve deeper, they realize the stone holds secrets far beyond their expectations, drawing them into the heart of a conflict much darker and more vast than they ever anticipated.
