The Adventurous Adventures of Ashley and Nathan [Shingeki no Kyojin / Attack on Titan

Nathan and Ashley were two best friends who liked to randomly stalk Ashley's neighbours, Eren and Mikasa, and sometimes, Armin would join them. Of course, the two weren't as close to Eren and Mikasa as Armin was, but they were all pretty close. Despite her random and crazy personality, Ashley was the kindest at heart and the most courageous out of all of them, while Nathan was calm and quiet. It was odd how the two opposites were really close, but hey - Ashley might've drugged Nathan!

But after 100 years of peace, disaster strikes, and all they can do is watch people they once knew and loved die right before their eyes.

Nathan - Your average 12 year old. Tall, messy brown hair, and strong. Oh, and maybe I should mention his scars.

Ashley - Not exactly an average 13 year old. I'd rather not call her, well, insane. She's a bit...wrong in the head. White hair, reddish brown eyes and a cheshire-like smile.
