This idea was taken from that done to death tumblr prompt. You'll be pleased to know Above you is not abandoned.
Gaara screamed the first time it appeared. A deep cut just above his knee, no blood, but he could see the bone.
He was still screaming as it faded away ten minutes later. He had never had an injury before. His sand shield had always protected him.
Baki explained that it was his soul mate who had been injured and that's why it appeared. That just irritated him more. He was to be Kazekage he didn't want to be caught up worrying about a mysterious soul mate all the time. But he did worry about them, they seemed to get injured a lot, skinned knees, deep black bruises and once a long cut from his torso to his pelvis.
He suspected his soul mate was a ninja too. He knew enough to know he would probably never meet her, him, them. They obviously weren't from his hidden village because he would have heard of someone getting cut from sternum to pelvis now that he had risen to the mantle. The scar never faded too, meaning it had been treated with poison. He suspected that his soul mate had probably died. He had read about that happening after Baki had introduced the concept to him.
After the fourth Shinobi war, more scars had appeared it seems his soul mate had survived after all. He had added some of his own to her as well, a distinctive deep cut on his fore arm.
As Kakashi took over as Hokage, Gaara travelled to Konoha with his siblings. Temari was moving there in a few months, her soul mate a Konoha ninja called giant-pain-in-his-ass Nara. Kankuro's soul mate was a civilian he suspected because he only ever got small burns on his arms. Kankuro hadn't met them yet.
Naruto got married to his soulmate, a small women with long blonde hair called Ino. Sakura and Sasuke were happy with each other, though privately Gaara thought that was a very strange relationship, he never saw them touch each other. Gaara suspected he would like to touch his soul mate, the tender moments between pain in his ass and his sister were very sweet. Though he would never tell her that.
It was at their wedding, Naruto and Ino's that is. That he saw her, the small bridesmaid with long purple hair and a distinctive scar on her arm, that matched his own, the cut of her dress showing a cut between her breasts.
He knew he was in trouble, the eyes alone told him his soul mate was a Hyuuga. The unmarked forehead told him she was THE Hyuuga, the heir. Gaara privately suspected Rock Lee's teammate also an Hyuuga would kill him. The woman spotted him, she scanned him briefly, and he could tell she already knew he was her soulmate, she winked and turned back to the bride.
Hinata was amazing, she accosted him after the ceremony, pushed up his sleeve, and demanded to know how on earth he had been stupid enough to get a cut like that, he was Kazekage for Kami's sake. Gaara just stared at her, last time he had seen this women she hadn't even been able to meet anyone's eyes, now she growling at him because of an injury he had received a year ago? Yet he found himself quite unable to look away. She went on to tell him off about the amount of ink stains he got on a daily basis, did he not realize they transferred to her as well. In the end he kissed her just to shut her up. Best decision he ever made.
