Born to a noble family of both shinobis` and kunoichis, Katsuki was meant to be someone to defend the honor of Sunagakure through the art of war which is what she originally devoted her life to. She spent her beginning years learning her families trade. However, as she tried her hardest to rise through the ranks as fast as he could, but her physical strength and skills were by no means at the level that of her siblings and relatives. The harder she tried, the harder she would fall and it seemed as though life continued to drag her down. In an ambush mission in the village that lied between Sunagakure and Konoha, Katsuki volunteered herself to attend in order to bring honor to her families name with a successful mission. Many thought the act was merely a display of her inability to perform as a strong kunoichi, but her family respected her, giving her a warriors ceremony - presenting her with the blood moon headband of her ancestors. A goodbye in case she never returns, a token to give to the fallen.

The ambush did not go in their favor, there were more men on the side of their prey than that of the predators. A bloodbath would ensue and casualties on both sides were seen. Katsuki, frozen in battle, was left to hide amongst her dead in hopes that they would simply leave however, as the sounds of bodies dropping like flies could be heard around her, a few masked soldiers walked towards the body, one grabbing the girl and bringing her to her feet. It was a boy, not much older than her, eyes like jade dragons that she prayed to in her home. That was when she met Kurai, and began her life as a missing nin and meeting the soon to be love of her life
