Blue and Green

It all started when the Colossal Titan kicked a hole in wall Maria. People screaming in terror and pain; frightening hundreds of people. The soldiers were preparing the ships so that the rest of humanity could get away from the Titans and begin to prepare for war.

Three particular children escapes safely. Mikasa Ackerman and Armin Arlert weren't raised by their mothers. However. Eren Jaeger was and his mother faced a horrible fate, eaten by the Smiling Titan. And Eren shall soon have his revenge. So with the determination of the three, Eren Jaeger, Mikasa Ackerman, and Armin Arlert shall join the military (scout regiment) as soon as they get the chance and end all of this Titan nonsense once in for all!

However. There is a girl, f/n l/n, who is willingly to risk her life for her friends and her captain, Levi Ackerman. She goes beyond the wall with no back up one day... Searching for herself that she lost long ago. When all of a sudden something triggers f/n memory to remember her past. What is she? Human or Titan Shifter? Can she also be the key to humanity or the destructor of the fate of her friends, captain, and comrades?

There is always that one thing that f/n follows truly and that would be her heart. Is f/n l/n ready to embrace for who and what she really is?
