Yes, and no. We took orders from the King because it was mutiny if we didn't. But the Scout Regiment had its own set of rules. Would this government permit teenagers to serve for them? From my understanding so far, those not yet considered 'of age' here have no reason to be working.
There's not much I'm willing to ignore, after what I've seen. I'd be interested in learning more about your world and demons, Sam. If they are an enemy that could be brought here, I'd like to do what I can to help out.
I served mostly to protect my friend, Eren. He saved my life when we were children and his family adopted me after my parents were murdered. I owe much to them. Eren wanted to join the military, so I followed.
Titans? You will know if you ever meet one. Titans are human-like, but they are tall. Some as tall as fourteen meters. They don't eat food or need water. As far as we can tell, Titans can't talk, either, and the majority of them do not have much intelligence. They can recognize the sound of a human heartbeat and live only to eat humans. It's...what we fear, what we struggle with every day.
Just before I joined the military, Eren's mother was eaten by a Titan in front of us. We were nine at the time, and shortly after, joined up with the military to try to prevent it from happening again.
