dragons devil daughter

this is the first time i would be doing a story. I will try my best.
This will be about a girl named Rias she lives with her grandparents but she only knows her mother and older brother and she question where her father is. What she doesn't know is that her father is Natsu Dragneel formly know as the eldest son of the gremory family. Though because he didnt have the power of destruction he father despised while his mother adored him and sirzechs just complete hated him. Due to this he left only to return and give his daughter to his mother so she can look after her while he isnt their for her. Through all the trouble rias went through all she knew was that when she need her father most he would come out of hiding and help in what ever endevers it was.
