Prologue
"I promised you that I'd never let anything happen to you. And I intend to keep that promise." Eren's hand cupped Kirito's cheek, and gave him a long stare
Kirito could feel tears welling up in his eyes, and he let out a sob.
"No! I'll fight alongside you!" He said, but Eren glared at him.
"No you won't! You will stay here with Mikasa and Armin!"
"I can fight! I've been trapped in a world and survived and slayed for two years!" Kirito yelled, and fisted his hands. They were both sitting on the floor, well Eren was crouched in front of him and Kirito was sitting, looking at him hopelessly.
"I know you can fight Kirito. But this is the world full of Titans; your world is nothing compared to these giant freaks." Eren then began to let go of Kirito, but Kirito grabbed his jacket, pulling him closer and wrapped his arms around his neck, hugging him tightly.
"Please just let me be with you! I can fight I know I can." Kirito cried out, tears streaming freely. Eren's eyes widened in shock but then smiled warmly. He put his arms around Kirito's neck and squeezed him.
"I will protect you. If-"
Suddenly, screams were heard everywhere-
The building they were at had already been invaded by titans.
"RUN!" A man yelled in the recon corps, screaming, as everyone tried to get away before the titan devoured them.
Eren clutched Kirito as he saw another titan, 10 meters, break a window and crashes the building wall.
"Run Kirito! Run!" Eren yelled, and let out a scream as he ran towards the titan, drawing out his swords and leaping one place to another. He sliced the titan's arm, but it wasn't deep enough. The titan groaned, and swatted at Eren, missing him but hitting his gas supply tank, and his wires for holding onto anything. This caused Eren to fall to one of the roofs of the houses, and the Titan was going straight for him.
"No! I must help him! I defeated a world of monsters, how can a titan be any different?!" Kirito said, and got up quickly, yelling out a battle cry and got his trusty heavy sword, and swung it hard to the titan's arm before it grabbed Eren.
The arm fell off, and Kirito changed gears, making hooks cling onto the walls of anything.
"Good thing I learned how to use these. Now how to kill you?" Kirito said to himself, as he swung himself around the Titan, facing his back.
"Go for the neck in a titan, always for the neck." Mikasa's voice said in his mind, and he nodded.
"ARRGHHH!" Kirito yelled, as he swung himself again, this time he dragged his blade to the titan's neck, wrapping wire around the neck as well because he'd been circling the titan. Then with a single motion he pulled back and watched as the titan fall before him, and never moved.
Kirito then swung himself and ran to Eren.
"Eren!" He yelled, as he grabbed Eren and pulled him to his lap.
Eren gave him a grin, in which blood came out of his mouth and nose.
"I guess I was wrong about you; you can fight." He coughed, and Kirito pushed his hair out of his forehead, and gave him a tight hug.
"You scared me! I thought that thing killed you!" Kirito said, and Eren once more, hugged him back.
"But you saved me. And Kirito, assure me with one thing-" He pulled back, and held onto Kirito's shoulders.
"Fight. Never give up. If you want to win in this cruel sadistic world, fight. Fight for everything you have left."
Kirito had tears in his eyes, but forced then to stop. He gave Eren a short nod.
"I'll always fight. I always have anyway! What do you take me for? I survived a deadly game! In which I defeated!"
Mikasa, Armin, Sasha, Jean and Asuna swing in just in time as another titan came in.
"We have to fight the titan off!"
Sasha said, and Kirito looked at Asuna who was staring back at him with a smug smile. Kirito smiled and broke off from Eren.
"Asuna and I will fight the titan and anymore who comes in our way. Just take Eren back safely." Kirito said, but just as Sasha protested, he ran towards the end of the roof, and Asuna followed quickly. Ignoring Eren's protest, Kirito grinned as they both gave each other a smile before they jumped.
