Little Freeces (Killua x Reader)

What if Gon wasn't the only child Ging had? What if Gon had a twin? What if Ging kept that sibling and left Gon behind with Mito?
16 year old Aria Freeces is Gon's younger twin who Ging decided to keep and raise by himself. She became a hunter when she turned 10 and is now a 2 star archeological hunter just like Ging and works alongside him in the adventures he goes on and was a student of the late Chairman Netero. Not only that, at age 8, she became the youngest child in history to become an certified state alchemist (BEFORE EDAWARD ELRIC) and was given the rank of a general by the age of 13.
As the time passes, she had no idea that she ever had a sibling, let alone a twin, until Mr. Bean had told her that Gon was in the hospital with a chance of dying after the Chimera Ant situation. This is the story of how her and Gon finally meet after being apart for all these years, their new life as siblings, and how a surprising love began to grow between her and a certain white haired boy.

(I do not own the hunter x hunter, Fullmetal Alchemist, etc. characters or the pictures I may use but I DO own my cover picture, my character, and this story line. IT IS NOT BASED BY THE SERIES OF ANY ANIMES I USE IN THIS STORY)

Extra....
1. This will take place AFTER the Promised day in Fullmetal Alchemist and after the Chimera Ant Massacre in Hunter x Hunter so this is MY own storyline.
2. Ed will still have his metal prosthetics and can still use alchemy and Al will have his original body not the Armor.
