Lore: :)
When Hitori was born, she was in a deep forest, her mother being human, and her father being a dragon. One day, The forest was invaded by Oni. Her parents, to keep her safe and alive, encased her in a stasis crystal. Where she won't age or grow for many years. Many years later, (During season two of ninjago) after the overlord was defeated, thats when her crystal began to crack. Master Wu soon found her, and broke open the rest of the crystal. Since the crystal cracked, it wasn't able to maintain Permanent stasis. So, she aged slightly into a toddler. Master Wu had given her to a family whom wanted a child, and was raised for sometime. Then, During a battle (season five, possessed) Her Home was destroyed because of the activation of morro opening the dead portal. Her parents died during that, and was now an orphan. She wandered for a while, getting kidnapped several times, and worked to the bone in some areas as a servant. When she turned 13, she discovered her Elemental power. At first, she used it to run away from enemies. Then, she started using it to help others with chakra dysregulation. She delved into the medical field and settled in a small village. During the terror of oni, (Season 10 march of the oni) the village she lived in was destroyed. Along with everyone in it being affected by the gas that emitted from them. She felt hopeless, but reminded herself that the Ninja wouldn't quit. So she wasn't going to hang the towel now. She met the ninja briefly, helping them battle and defeat the oni. Which later leads to her facial injury, which was during the final battle of the march of the oni. After that, she went back to the village, and helped rebuild it. As she remained a healer there. Then, during the reign of terror because of Aspheera (season 11), she felt a pull, connecting to the Never Realm. She then found a way to go to the realm, where she would find her true potential there. After that, She trailed the ninja for sometime, having already been fans of them in the past, but one of the ninja in particular caught her eye. The green Ninja, Lloyd Garmadon. She of course ran into so much trouble while following the ninja, getting used, finding friendships and losing friendships, and heartbroken from an evil crush (Morro). She lay low for a while, and found a mentor. The Mentor was a source dragon, the Source dragon of Chi. where she would later learn to master her Elemental power. Her Mentor, told her she was ready. The source dragon of Chi, told her to go to Shintaro and dwell there. For it was a peaceful realm. She gave Hitori the ability to Realm jump, leading her to a home she would live in for a while. But then, during The game of prime empire (Season 12) Her master had disappeared. She searched everywhere, high and low, whilst avoiding some enemies, and battling a few. Once prime empire ended, she could not find him. Then, she decided to disappear for a few years. Later, when the ninja had come to Shintaro, She had found out about them arriving. She was excited, but at the same time panicked because didn't know whether Lloyd was still a ninja. Then, the night after they arrived, she would be climbing a tree to see vania. That is where Lloyd would be sneaking around, as he startled her. She fell out of the tree, and he helped her up.
