Not too long after, perhaps a month or so the worst seemed to come for both Hinata and Gaara. For Hinata she went through grueling training with her father and Neji. Day after day of bloody training was what she got and fight after fight with Neji and her father until she was sore and out of breath and it only got worse after her mother died and then her father grew colder and more serious, like the Kazekage, in fact, their eyes were the same now.
Ever still, Hinata was trained and battled with daily and learning how to use her Byakugan and many other fighting techniques and jutsus. Neji began to get bitter and angry like Hiashi and stopped caring about his cousin, in fact he despised her, calling her the weak link in their clan. Years went by and it seemed Hanabi surpassed Hinata in every fight and trained better than her. Hiashi said that Hanabi would make a better heir than Hinata in every way. The girl felt like if she trained harder then no matter how gentle, shy, caring, soft, and sweet she was she could be a fighter and surpass her cousin and even her brutal sister but she feared it would never happen.
In the Suna things were even worse for Gaara. His own uncle, Yashamaru, tried to kill him and while doing so told a lie about Gaara's mother and himself that shattered Gaara's mind and heart into pieces. He never felt such a sharp pain run throughout his body, tears poured and poured down his cheeks, and a boiling fury that blinded his sight flashed through him like lightning and in that second of unbridled fury Gaara used his sand to murder his uncle.
In the end Gaara realized nobody loved him and nobody ever would except for the demon within himself. He carved the word "love" on his forehead and told himself that he loved himself and that is how it would always be. The demon raged within Gaara giving him a newfound bloodlust, anger, and a chilly demeanor which included no mercy or pity on any puny human. Gaara was riveted with power and Shukaku's sinister voice in his head, ruling his thoughts and judgment. As long as Gaara thought he was alone and that everyone deserved to end their insignificant, miserable, pointless lives at his hands, the Shukaku would be in control.
Gaara descended into a full-bodied insanity and was hell bent only on killing every mortal who crossed his path, even his siblings if they dared to infuriate him. His demeanor was frosty and malicious, a stone cold killer. Shukaku penetrated Gaara's mind and broke his skull wide open with evil intentions and malicious thoughts of murder and thus Gaara forgot all about Hinata and their promise but only partially so. While Shukaku remembered he didn't let Gaara in on it for he thought Hinata was a distraction to his plans to dominate the world, create havoc and chaos and shower the earth with blood. Still, Gaara wore the ring for some unknown reason, most likely for the same reason he kept his teddy bear.
So while Shukaku was busy using Gaara as his puppet, he never knew the one girl he tried to push out of Gaara's mind would suddenly pop up in the chunin exams and shake Gaara and Shukaku's world upside down and maybe, just maybe she could be the key to installing memories and feeling into Gaara and fear into Shukaku if it wasn't too late to get into Gaara's shattered mind and black, cold heart.
