I believe soul mates are possible, you just don't find them often. Keeping that in mind will help you understand the majority of my work.
I know. I write OCs A LOT. And they probably would tend towards being Mary Sue's if they didn't have significant trauma in their past or psychological scars that about bury them in scar tissue. Anyway, I'm going to explain my OCs so you can grasp my oneshots and drabbles, mostly interesting moments from this fanverse.
Fidelia, Hope, Faith and Honor Desjardins- Fidelia and Hope are sisters. They are a French Wizarding family, and these two graduated from Beauxbatons. A French Death Eateresque faction chased them to England, where they gave their daughters into the custody of Amaya. Once in Konoha, they meet and bond with Shisui and Itachi. Hope is Honor's mother, and Fidelia (who goes by Delia) is Faith's. Fidelia and Hope are both dirty blonds, Honor is a pale blond (her father is a deceased Delacour), and Faith is a redhead (her father is Fabian Weasley). They fled to England because Delia's lover and Faith's father was there.
Amaterasu "Amaya" Uchiha Hatake. Officially on a seven year training journey, she was actually attending Hogwarts. She returns to Konoha several times- to attend the Kyuubi funerals, to place Faith and Honor in Kakashi's custody while she is in school, and to witness the birth of her nephew, Neji Hyuuga. She is married to Kakashi, married at a young age because either she could die when she got back, or Kakashi could die before she finished school. Her nuclear family as a child consisted of two older siblings- Nejimaru Uchiha, who died as a genin, and his fraternal twin sister Akita Uchiha Hyuuga (Yes, I set her up as Neji's mom because he deserves one and Hizashi deserves to be loved) and her parents, Katon and Aishiteru.
Akita U. Hyuuga. Died in the massacre.
WHY IS KAKASHI DIFFERENT/MARRIED?
Because in canon, there was no one to crack the whip and say "Teach them or no blowjob/sex/cuddles." (Now that I think about it, just because most if not all of my pairings are straight, I really need to write a yaoi of some sort- I support those who are LGBTA, but it has yet to really enter my life on a personal or familial level). Amaya is in no way perfect or whole. She just does what any strong woman does- tough it out in front of the public, break down in hubby's arms- when he's home and the others can't hear. She will break her own heart, distrust Kakashi, you just won't see much of it.
IRON STEEL STYLE
This is not a jutsu. It is a partnership style that was developed by a matriarchal offshoot of the Uchiha clan. Instructors are known as Iron Mothers and Steel Fathers. Journeyman fighters, who have passed their Trials (where their most competent sensei must be beaten in every art pertaining to the style, boys take Steel Trials, girls take Iron Trials) are known as Iron Daughters and Steel Sons, while acolytes, or those preparing for the Trials, are known as either Iron Acolytes or Steel Aspirants. There is a story about the exact creation, which I will tell. Current pairs trained in the style are:
Iron Grandmother/Steel Grandfather (retired heads of the order)
Aishiteru U + Katon U. (both deceased)
Iron Mother/Steel Father
Akita U. Hyuuga + Hizashi Hyuuga (Dojutsu and Taijutsu) (both deceased)
Amaterasu U. Hatake (in hiding) + Kakashi Hatake (active Leaf Jonin) Sharingan & Katana, Sharingan & ninjutsu
Iron Daughter/Steel Son
Faith Desjardins Uchiha + Shisui Uchiha (both deceased) katana & Sharingan (kotoamatsukami) and Shunshin
Honor Desjardins Uchiha + Itachi Uchiha (both rogue) katana and mednin jutsu & Sharingan (Izanami) and ninjutsu
*Although both Shisui and Itachi married their partners to protect them, this is not guaranteed of every pair.
