The Compatibility of Guardian Characters and Hunters

Mia is an adorable, well-behaved little girl with long, curly black hair. She grew up with her father, Jin. By the time she was six, she had gradually acquired three Guardian Eggs of her own. She wanted to become a Gourmet Hunter, so she got Xiao Fei. She wanted to become a Music Hunter, so she got Xiao Ya. She wanted to become a Magical Beast Hunter, so she got Xiao Ke. I haven't figured out the blurb yet. The pairing is Killua. I'm trying to start this story for my precious Killua. The heroine is Gon's biological older sister, raised by Jin, while Gon is still raised by Mito. The heroine is fairly capable and has a golden finger. I don't like putting my girls through angst, so this should count as a sweet little story? The characters will definitely be out of character, and my writing is amateurish. I can't promise I'll finish it, but I'll try to keep updating. (I'm usually diligent and consistent early on, but later I may only update when I feel like it. As long as my love for Killua runs deep, I'll keep trying to update.) Theme: Strive to become a better version of yourself!
