Ereri- /The World Before Us/

Chapter 1: Flashbacks~

Eren kicked the ball across the big front yard to his mother and sister, his mother instantly missing it. Eren laughed but stopped when his sister, Mikasa, kicked the ball hard at him. He dodged and scowled in her direction.

"I'll get you back for that, show off!", The ten year old shouted.

"I'd like to see you try", Mikasa replied loudly, waiting for the ball to be kicked back at her with equal strength. It was, Eren kicked it just as hard at her, with a smug look on his face.

"Now, now", Carla, his mother, smiled cheerfully in the kids' direction, "There will be no fighting for this game, it'll be a fair one, so I'd suggest you'd both calm dow-"

A loud scream was heard, and suddenly a man covered in blood came out of a house near the three. He saw them and ran towards them. Carla barely had time to think before the ugly-ass guy jumped on her and started biting at her flesh. The two ten year olds screamed for help and for the man to get off of her, but he didn't listen. Eren stepped forward in fighting position, but the man turned to him with a hungry expression on his made Eren step back in fright, and Mikasa grabbed his arm and they both ran into the house.

Mikasa quickly pressed the button on the wall next to the door to put the whole house on lockdown for their own safety. They both seemed to be in shock, they couldn't register what had just happened. After a short silence, they started talking about the awful smell that spread through the air a few hours before the incident, and how it was exactly like some horror movies they'd watched. A stinky gas filling the air and some rotting guy comes up and bites Carla to death. They talked.

A few hours after that, Mikasa broke down and started bleeding out of her eyes, mouth, nose and ears, Eren tried to help but had no clue what was wrong. She eventually died, and Eren stayed by her side, crying, and holding her lifeless body to his chest, sobbing away. Before finally wiping away the tears and going into the bathroom of his own room and washing his sisters blood from his clothes.

When he walked out, he was faced with an emotionless Mikasa, standing right before him. Covered in dry blood. She tried to kill him but he fought back, and killed her instead. He physically killed her, but at the same time, he mentally killed himself. It took everything he had to kill his sister, and now he was alone.
