Author's Note: This story takes place when Wall Maria is attacked.


During the year, Eight Forty-Five... Everything within the Paradis walls seemed peaceful. The Titans were restricted from entering the Wall Maria and everyone had continued living their normal lives. The sky was orange as the sun was setting.

Carla Yeager, whom had finished wiping plates was still standing over the kitchen sink. She couldn't help but think of the argument she had with her son, Eren. She didn't approve of Eren wanting to join the Survey Corps. She sighed as she stared at her own reflection through the window.

Knock. Knock.

"Oh?" Carla Yeager had looked to the front door and walked toward it. 'Are Eren and Mikasa back already?' She had gently grabbed the front doorknob and twisted it. She had then opened the door, and then...

"Eren. I gave it some thought about your decision of you wanting to-" Carla Yeager had then stopped mid-sentence when she noticed a random person standing right in front of her on her family porch.


Meanwhile...

Three young adolescent children named Eren Yeager, Mikasa Ackerman and Armin Arlert were sitting by a small river where ferries float on.

"I believe that people who live in the walls have their hopes too high-assuming that the walls will be safe for another century. Just because, the walls hadn't been breached for over a hundred years-doesn't mean that it won't be breached, today. It's only a matter of time." Armin said as he looked at his own watery reflection.

Eren had sighed.


Meanwhile...

"Um... can I help you?" Carla had asked as she stared at the unknown person.

"Hello. My name is... Kruger. And I am here to see Doctor Yeager for a doctor's appointment." The Nineteen year-old Eren had said.

Carla Yeager had continued staring Adult Eren down. She had previously assumed that her young son, Eren would return home. But had easily mistaken as the person whom appeared before her was her future adult son, Eren. She had stared at the man-not knowing that he was her son. His hair was tied in a bun. His pair of eyes were the color, Emerald green. He had also worn a long-sleeved white T-shirt and dark pants underneath a long black mantle that goes down to his back pockets.

"An appointment?" Carla questioned.

"Mm-hmm." Adult Eren had nodded as he made eye contact with her.

Carla had stared into her adult son's green eyes for a moment. "I'm sorry. But, I'm afraid that my husband is on a business trip and that he won't return for a few-"

Suddenly... the ground had rumbled, which caused a majority of the Shiganshina to shake. Most people had begun to lose their balance. "Mmph!" Carla had lost her balance a bit. She gasped as she was about to trip and fall, but she had suddenly been caught by Adult Eren who bent a knee and grabbed her shoulders.

"Are you okay?" Adult Eren had asked in concern.

"Mm-hmm. I'm fine." Carla had nodded.

'That rumbling just now... this must mean that Warrior Unit had arrived and that Bertoldt must've already transformed into the Colossus!' Adult Eren had thought of Bertoldt Hoover, when he had transformed into the Colossus Titan. Eren had then looked to his mother. "Come with me." He said as he helped Carla stand on her feet.

"What? Where are we going?"

"It's not safe, here." Adult Eren told Carla.

"But, this is my home. And my children hadn't returned, yet." Carla had replied.

"Don't worry. I'm sure that your children will be okay." Adult Eren had then thought of himself when he was younger, and a younger Mikasa Ackerman.

"But, how do you know that? How do you even know my children?" Carla asked, Adult Eren in a confused manner.

"Because, I've seen them fight, before." Adult Eren had replied.

Carla had gasped.

Adult Eren had then helped walk Carla a bit, before Carla had stopped and gently removed herself from her adult son's clutches. "Wait! If what you say is true, then, please allow me to gather a few my things." Carla had asked.

Adult Eren had stared at his mother for a few seconds, then nodded toward her. "Okay. Please, hurry."

Carla had nodded back to Adult Eren, then ran back into her home.

After watching his mother run back into his old home, Adult Eren Yeager had then turned his attention toward the front gate of Shiganshina District. He looked above and saw the Colossus Titan peaking his head over the wall and staring down at the city.


Meanwhile...

Dozens-if not hundreds of citizens were staring directly at the Colossus Titan within Shiganshina. Even the three adolescents such as Kid Eren, Mikasa and Armin.

"That can't be... the wall is supposed to be at least fifty meters tall!" Armin had frowned as he stared at the Colossus Titan.

Kid Eren's eyes were widened and open in shock. "Oh my God... it's a Titan!" He had pointed out as he stared at the Colossus Titan.


Meanwhile...

Adult Eren Yeager had remained outside of his old family home and stared at the Colossus Titan from a further distance than his younger counterpart. He was not afraid or terrified. He frowned as he had know that the Colossus Titan was his former comrade, Bertoldt Hoover. 'It's about to begin, soon! I won't make it in time to save everyone!' Adult Eren had looked back to his old home, where his mother was inside of. 'But, at least I can still save... He then quickly looked back to Bertoldt, whom had already taken a punt kicking position. 'Here he comes!'

The Colossus Titan had swung its right leg down. Destroying the front exit gate of Shiganshina District. Large chunks of debris had broken off from the front gate and was sent flying in the air.

As Eren had stood there... 'Now's my chance!' He saw a giant boulder fly directly in his direction. And he knew where this boulder was going to land. Eren had wasted no time and quickly used the power of the Warhammer Titan to conjure a large wall made from Titan flesh. The wall nearly covered the roof of Eren's old home.

The boulders had soon collided with the pillar. Causing it to break apart. Saving not only Eren's old home... but also his mother.

'Alright. I just saved mom. Now I just need to find...' Adult Eren had thought, confidently.

"Okay, I'm ready!"

Adult Eren's thought process was interrupted when he heard his mother's voice. He looked back to see Carla with a suitcase in her hands.

Carla had then taken a few steps forward. "Thank you for your patience, Kruger. I am ready to find my-" Carla had gasped when she looked at the conjured wall made from Titan flesh. "What on Earth is going on?" She asked as she had almost dropped her suitcase.

"The walls are being attacked! And the Titans had gotten through, somehow!" Adult Eren had said.

Carla gasped, again. But this time, she dropped her suitcase. She was horrified. "What?"

"Please, wait here. I'm going to get help!" Without warning, Adult Eren had then ran toward the direction of the front gate. Leaving Carla shocked.

"W-wait a second! Kruger!" Carla had called as she extended her right hand out toward him. As Eren was leaving her sight... she then noticed something about him. She saw that Eren's right ear was red. 'His ear... it was red. Just like...' Carla had suddenly thought of her son, Eren who had a red ear on his head. 'They had similar red ears. And they both share the same colored eyes. And their hair color. Could that mean... no. That can't be right. Kruger is a totally different person.'

Carla had waited a few more minutes, until she heard the voice of her son.

"Mom! Mom!" Kid Eren had cried out in worry as he and Mikasa ran back to their home.

Carla had ran into the street only to meet her son, Kid Eren and her adopted daughter, Mikasa Ackerman. "Eren! Mikasa!" Carla had quickly reunited with them and hugged them both.

"Mom, you're okay!" Kid Eren had cried out.

"Misses Carla!" Mikasa had cried out.

"I'm glad that you too are alright." Carla said in relief.

"W-what happened, here?" Mikasa asked as she looked at the conjured wall that protected Eren's family home.

"I don't know what caused this, but we have to get out of here, now!" Carla said with a worried look on her face.

"Mom..." Kid Eren had replied.

"I need the both of you to listen to me and listen to me good. The Titans have somehow breached the walls. Shiganshina is no longer safe for any of us! I need your both to get inside and pack your things-take only the things you need." Carla had demanded.

"Got it!" Mikasa had nodded, then ran inside her adoptive home.

Eren had stood watched Mikasa run in their family home.

"Eren!" Carla had shook her son. "Please..." She said as she tried not to make her eyes water.

Eren had stared at his mother for a moment, then nodded. "Okay, mom!" He then ran inside of his home.

Carla had begun to walk back inside her home, until she stopped at the door. She then looked back at the front gate where Titans were roaming through. 'I know I just met you, but... please, be safe. Kruger.'


Meanwhile...

As the Titans were currently roaming into Shiganshina District through the breached gate... Adult Eren Yeager had continued running toward the front gate.

'Okay. I only have one chance to make this right. I cannot fail!' Eren had thought as he kept running through the streets that Titans had not roamed through, yet. As Eren had made a sudden turn to the right... he suddenly stopped and suddenly noticed a Titan that is standing at almost fifty feet tall in front of him. The pure Titan had blue eyes... a devilish grin and long neck-length blonde hair. It was looking elsewhere.

Adult Eren's eyes narrowed as he stared at the pure Titan before him. 'There you are. I've finally found you.'

The Pure Titan had suddenly looked downward and stared at Adult Eren. Its mood did not change.

'Dina!' Adult Eren had thought.
