Im a monster Reader

Why, why am I like this. I'm a demon that kills people. When I feel I need to kill, the symbol on my chest that stands for demon (you can search it up) starts to glow (f/c) so your demon sword (the one in the picture) comes out. I would slay all the people who came out I was very strong and impossible to stop me. The scouting regiment wanted to capture me and use me as a weapon for there own use. Hell no, I'm not giving myself to them so they can use me as a puppet. I have considered it once and awhile but would if they tried killing me. "Ugh life is so confusing!" You said moaning. All of a sudden a net falls on you. Captain Erwin comes out of the bushes with Hanji Zoe following behind. "YAHOO I finally caught you (y/n)!" Hanji said jumping around. "Hahahaha" they both stared at me in confusion. "You think you can capture a demon!" All of a sudden the net starts to burn. Wants it's done burning you summon your demon sword. You try to strike Erwin but someone's sword blocks it. Right away the other sword breaks. "Ha you think you can stop a demon sword?" You said backing up. "Tch, brat." the short man said. "We'll it was nice talking to you, bye." right after that you ran the other way with extreme speed. levi was about to chase after you when he heard the flare gun being shot off. The color was yellow. (I made this up, it tells Eren that he needs to transform) all of a sudden a yellow lightning bolt struck the earth. "ROARRRRRR!" Erens titan roared. "Heh, really they think a stupid titan shifter can catch me." you said under your breath. You started running in a different direction so you wouldn't run into him. All of a sudden your head started to hurt. "What the hell, they brought priest into this." all of a sudden ten priest surrounded you. They joined hands and said in union. "DEMON, YOU WILL NOT ESCPAE THE BARRIER!" They keep on repeating this. "AHHHH!" You screamed. Your true form was shone. You heard gasp all over. Your true form was a six foot "thing" in a black cape with demon wings. There were two holes in the back so the wings could come out. You had black eyes with red pupils. Your teeth were as sharp as your demon sword but now your demon sword was two times it's normal size and blue flames surrounded the tip. To people you were repetitive but to demons I was a demon sent from the lowest hell ever, where satan lives (that's good). You laughed and laughed. "I am a god, no I am satan in disguise (not really) I am invincible!" Right after you said that the barrier broke. You flew into the sky. You decided to spare them even though it was very impressive and fun to kill people in my true form. You did your evil laugh so everyone could hear it and flew off.

Three days later
You were in your regular form, siting in a tree when all of a sudden you hear "hello? I'm all alone, is anyone there." well we'll we'll it's the titan shifter Eren Yeager. You thought in your head. "My name is Eren and I transformed into a titan and was left here, they must of forgot me." He said almost on the verge of tears. "No you are not alone but I will send you home if you tell them to leave me be an never return to this forest, and if they do I will kill you." You said. "Yes yes yes I will I promise!" "Very we'll then." Right them and there you summoned your wings, swooped down and flew him home.

Months later you grew very lonely so you flew to Erwin, gave yourself to him and killed all the titans.
