Attacker You!: Season 1

For over a century, humans have been living in settlements surrounded by three 50-meter gigantic walls, Wall Maria, Wall Rose and Wall Sina, which prevent the Titans, giant humanoid creatures who eat humans, from entering. Eren Jaeger, of the town called the Shiganshina District, wishes to see the outside world by joining the Scout Regiment, as he likens living in the cities to being like livestock. His resolve impresses his father Grisha Jaeger, who promises to show him what lies in their basem

Hannes apologizes to Eren for being unable to save Carla. He is able to escape to the inner Wall Maria with Eren and Mikasa but the Armored Titan breaches that Wall as well, causing those inside to retreat even further, behind Wall Rose. Eren has a strange dream in which his grieving father forcefully gives him an injection and a key. Angry and bitter, Eren grows disgusted with the people of Wall Rose when they show disdain for sharing their food and resources with the refugees. During the next

The drill instructor Keith Sadies inspects the new recruits of the 104th Cadet Corps. Eren develops a rivalry with Jean Kirschtein, who desires a safe and easy position in the Military Police Regiment within the inner city walls, as they do not have to fight Titans or go on expeditions outside like the Scout Regiment. The recruits train on an omni-directional mobility gear apparatus, where they have to balance themselves while suspended on cables. After Eren has trouble balancing, he asks Reiner

It's been five years since Wall Maria fell. Keith evaluates the recruits for their strengths and weaknesses. After training in hand-to-hand combat with Annie Leonhart, Eren learns that Jean and several other recruits still hope to join the Military Police Regiment to avoid having to fight Titans. On graduation day, Eren and Mikasa rank among the top ten of their class. They are eligible to join the cushy Military Police Regiment, but Eren joins the Scout Regiment on the front lines, leading Armi

The Colossal Titan vanishes in a burst of steam before Eren can attack. The Military Police Regiment scrambles to evacuate the people of the Trost District and set up defenses. With the Titans now in the city, Eren recalls his lessons: in order to kill a Titan, they must strike the nape of its neck. In the chaos, Eren and Armin's comrades are killed or eaten by the Titans, with Eren himself losing his left leg when he attacks in haste. Armin, paralyzed with fear, is picked up by a Bearded Titan.

Armin awakens to find himself surrounded by Conny Springer, Christa Lenz and Ymir, blaming himself for Eren's fate. An Abnormal Titan approaches the city gate, which is crowded by refugees. Mikasa kills it with her atypical, powerful prowess, saving everyone. A flashback to the year 844, a year before the fall of Wall Maria, shows that Mikasa's family was targeted by three slave traders, who murdered her parents. Grisha and Eren discovered the corpses during a visit and Eren tracked down the sla

The surviving squads, unable to reach the inner walls due to their omni-directional mobility gear being low on gas, lose their fighting spirit as the headquarters and supply depot are overrun by Titans. Mikasa learns from Armin that Eren is dead. She rallies the others to reclaim the supply depot by taking down the Titans but runs out of gas and falls into an alley. Jean assumes command, but loses his nerve momentarily when he sees his comrades being eaten. He eventually makes a judgement call,

With the supply depot swarming with Titans, Armin has the idea of luring the mysterious Titan there to defeat them. His plan works, but while the mysterious Titan is able to kill the enemy Titans outside, seven smaller Titans are in the fuel storage area. With their equipment out of fuel, Armin devises another plan. The survivors shoot the Titans in the eyes to blind them, while seven others jump to finish them off. This, too, is successful and having replenished their fuel, the soldiers prepare

Captain Levi of the Scout Regiment and his squad are on a mission retaking a town from the Titans, but are called to the Trost District when the Titans invade. When Eren was swallowed alive by the Bearded Titan, he found himself in its stomach with the bodies of its victims. His rage at the Titans caused him to burst out of the Bearded Titan's stomach by transforming into a Titan himself and going on a rampage. Eren's comrades, who witnessed him emerge, agree to keep it a secret; however, Kitts

Eren detaches himself from his Titan's body and climbs out, telling Mikasa and Armin about the basement in his old, destroyed house. His father was working on a secret project there and he believes that it holds the secret to mankind's preservation and destroying the Titans. As the cannons are reloaded for another attack, Eren comes up with two escape plans. The first is for him to flee as a Titan and journey to his old house but criminalize himself, and the second is to have Armin convince Kitt

As Armin helps Pyxis's subordinates coordinate a plan, morale among the troops begin to drop at the thought of facing the Titans again. Pyxis reminds them that if they abandon their posts, they will be subjecting their families to the same terror they faced; this convinces the troops to stay. Claiming that Eren is the result of a secret project to turn humans into Titans, Pyxis plans to have most of the troops gather at a far corner of the Trost District to lure most of the Titans away while Ere

Mikasa tries to reason with Eren's Titan form, but to no avail. He accidentally incapacitates himself, slumping to the ground. The elite squad protecting him sends up a red flare to signal that the plan has failed, to the dismay of the rest of the troops. As Armin heads toward Eren to investigate, the elite squad argues about withdrawing and abandoning him to the Titans but Captain Ian convinces them to protect him even while he is incapacitated, recognizing Eren's potential as a valuable asset.

Jean escapes with Annie, Connie and Marco Bott's help. To everyone's surprise, Eren in his Titan form starts carrying the boulder toward the gate. Captain Ian orders everyone to protect him. As the soldiers fight off the Titans, Eren successfully blocks the gate. Rico fires a yellow flare to signal that the operation was a success. When Armin and Eren are cornered by two Titans, Levi saves them just in time. In the aftermath, all Titans remaining in the Trost District are eliminated and two are

The populace is divided over whether Eren is their savior or their end. He is brought to a military tribunal where Commander-in-Chief Dhalis Zachary will decide whether he should be handed over to the Military Police Regiment or the Scout Regiment. The Military Police wants Eren executed, seeing him as a danger, while the Scout Regiment wants to use his ability to retake Wall Maria. Eren angrily calls out the Military Police for their cowardice and selfishness. Levi brutally beats him in retalia

Levi and his Special Operations Squad, composed of Eld Gin, Oruo Bozad, Petra Rall and Günther Schultz, bring Eren to the old Scout Regiment headquarters, where he will learn to control his Titan powers under their watch. Erwin and Miche Zacharius discuss how they must prove Eren's usefulness to the Military within a month but Erwin hints that there is another reason for Eren's presence and the upcoming expedition. Hange asks Eren to help in experiments with the two Titans they've captured, whic

As the recruits are investigated over Sawney and Beane's deaths, Annie joins the Military Police Regiment. The 104th class of cadets are greeted by Erwin at the Decision Ceremony, where he informs them that the goal of the Scout Regiment's expedition next month is to reclaim Wall Maria so they can enter the Shiganshina District and uncover the secret in the basement of Eren's home. He tells them of the Scout Regiment's high mortality rate, since they are the military branch responsible for outsi

As they begin the 57th Expedition, the Scout Regiment assembles into their Long-Range Scouting Formation, wherein they spread out in a semicircle around the main wagon train and signal by colored flare guns if Titans are nearby so the group can collectively alter course to avoid conflict if possible. Things get difficult when a Female Titan suddenly appears at high speed toward Armin's squad. Much to Armin's shock, this Titan is intelligent enough to kill his seniors and protect her neck. She ca

Armin, Reiner and Jean are left with only one horse after their encounter with the Female Titan. They are saved when Christa arrives with extra horses. To everyone's surprise, the operation is continuing, albeit heading in a different direction. News reaches the center group about the annihilation of their right flank by the Female Titan. The formation breaks entirely as the Scouts all reach the Forest of Giant Trees; only the center row enters while the rest defend the forest from Titans. Eren

Levi fires a noise round and tells the squad to keep moving forward. With more of the rearguard being killed by the Female Titan, Eren begs his squad to let him fight, but they tell him to trust Levi's decision. Eren recalls when he was unable to transform into a Titan for experimental purposes for Hange and the squad. During a break, when he tried to pick up a fallen teaspoon, he unexpectedly partially transformed, leading the squad to panic and Hange to deduce that he is able to transform not

Though the Female Titan is restrained, the squad is unable to extract the human inside as she is able to crystallize her skin to prevent them from cutting her skin. Everyone realizes it was Erwin's plan to use Eren as bait to draw out the mole within the army who joined them after the Walls fell; that's why he kept the plan from all current members and only revealed it to those who were part of the Scout Regiment before the fall. The Female Titan suddenly hollers a scream that draws all Titans i

Erwin realizes it was a mistake to think that all intelligent Titans are like Eren, since the Female Titan has abilities far beyond that of a novice. The mole once again transforms into the Female Titan and chases after Levi's squad. Armin theorizes that the mole is someone who had seen Eren transform during the invasion of the Trost District. Eren wants to transform but the squad tells him to trust in their skills to protect him. Eld, Oruo, and Petra manage to blind the Titan; however, she rege

Levi debilitates the Female Titan at incredibly high speed so that she can't even crystallize her skin in time. He injures his leg when saving Mikasa but is able to retrieve Eren from the Female Titan's mouth, as she is now badly wounded and slumped against a tree. The Scout Regiment somberly retrieve the corpses of their fallen and begin the journey home. On the way, they are chased by two Titans. One is killed by Mikasa and they outrun the second after Levi orders them to dispose of the corpse

In the Stohess District, the Military Police Regiment are ordered to escort the Scout Regiment convoy once they enter the capital. Annie's colleagues Hitch Dreyse and Marlo Sand are in the Military Police for opposite reasons, one for its corruption, the other for its reformation. After the convoy has entered, Armin secretly calls Annie away and begs for her help in smuggling Eren out of the capital so the Scout Regiment has time to gather proof to keep him. The one riding in the convoy is Jean

A few days earlier, Eren was informed by Erwin that Annie was suspected to be the Female Titan, thanks to Armin's deductions, and how they plan to capture her. In the present, Eren tries to transform but is unable to as his feelings for Annie are holding him back—he is unable to accept that someone he trusted turned out to be the Titan. He is then heavily injured from a tunnel collapse. Commander Nile Dawk of the Military Police Regiment demands an explanation from Erwin, holding him at gunpoint

A group of worshippers who idolise the Walls are ironically crushed by Annie, leaving Minister Nick the only survivor. Eren and Annie fight in their Titan forms throughout the Stohess District, causing destruction and civilian deaths. As this was Erwin's operation, he accepts responsibility for the damage and is arrested by Nile. Annie is overpowered and attempts to escape by climbing up Wall Sina, but Mikasa cuts off her fingers. Eren prepares to eat the human Annie but Levi stops him as she mu
