Even as a Girl, I Will Change the World

Huh, I'm a child of God, but why am I a little girl? Why are there powerful beings, second only to gods, trying to destroy Earth? And what else is going on... "I'm a total newbie among newbies, and my writing isn't very good, so please forgive me, okay?" (Important note: this is just a trial run! I'm not very good at writing novels, but I wanted to give it a try anyway ≥﹏≤)
