Hikatoko Ōtsutsuki

Hikatoko Ōtsutsuki (大筒木悲歌常, Lit. meaning; Big Bamboo Tree's Endless Dirge) is a priestess and part of the all powerful Ōtsutsuki clan. Having fallen in love with a Branch Family Ōtsutsuki, she had kept the romance between the two secret for as long as she could. But eventually, word came out of their love. The Branch Family Ōtsutsuki was executed, and Hikatoko, distraught over the actions her branch took, rebelled and waged a war against them. Losing the war, she was considered a traitor for falling in love with a Branch Family Ōtsutsuki and for breaking her vows, and her illustrious Byakugan, the Ōtsutsuki Clan's most cherished dojutsu, was sealed away into the moon, and Hikatoko was sent to Earth to live the rest of her days, never to return to the moon again. Living on the earth for centuries, she kept herself hidden from humanity, almost never revealing herself to the humans. Some call her appearances divine intervention, others call them a fatal curse. In secret, she adapted to the planet's culture, trying to become ingrained into their society.

Background
Hikatoko was born to the Main family of the Ōtsutsuki Clan, and was expected to uphold the grand traditions of the main family. As such, she was given royal treatment, including studies, training and everything else in between that the Ōtsutsuki had to offer their main branch members. During this time, the Main Family was at war with the Branch Family, who believed that Hamura wanted the earth destroyed if humanity didn't follow Hagoromo's teachings. Though she didn't agree with those methods, all the same, she had some distrust over humanity weaponizing Hagoromo's teachings of ninshū. On the other end was a Branch Family member who had similar views; He didn't believe that Hamura wanted the end of humanity, but he also was uneasy about humanity weaponizing ninshū into ninjutsu. Regardless, both of them saw the best in humanity, believing they can still find peace. The two fell in love in secret, keeping their love a secret from both clans. But as the war waged on, it didn't take long for their romance to be revealed. Captured by the main family, the branch Ōtsutsuki was executed publicly. Personally observing the execution, Hikatoko's anger reached a breaking point. Lashing out against the Main Family, she attacked them personally. But even with the help of the Branch Family, she was defeated. With her defeat, she was casted out as a traitor against the Main Family, one for falling in love with a Branch Family Ōtsutsuki, and for breaking her vows of upholding the laws of the Main Family. Using their powers, her Byakugan, the Ōtsutsuki clan's most cherished dojutsu, was sealed away into the moon. But she got her payback when she had absorbed the powers of her Byakugan into the Rinnegan in her right eye shortly before her defeat.

With the sealing complete, Hikatoko was banished to Earth, where she would spend the rest of her life. Days passed, and Hikatoko struggled to get used to the difference in atmospheres compared to her home. Finding a cave, she took shelter there. Over the course of months, she turned it into her home, where she would spend the next several centuries hiding from humanity. Every so often, she would leave the cave for food and water. Those who would see her would deem her appearances either divine intervention, swearing they have bouts of great luck seeing her, while others saw her as a curse, believing their string of bad luck came from her appearances. Finding this human culture so ingrained around luck intrigued and confused her, so during her free time, she would observe the nearby village in secret, observing the patterns of the people. It was during this time she would stumble upon a descendant clan of her own; The Hyūga Clan. Studying their training, she found how they used their Byakugan to create a graceful fighting style based around taijutsu and the manipulation of the body's tenketsu; The Gentle Fist. With barely any pressure behind their attacks, they can shut down the body faster than hard strikes could, even completely paralyze their foes in seconds. Using her Byakugan enhanced Rinnegan, she saw how the chakra in their hands pushed outward in short, controlled bursts with each attack, meant to overload the opponent's tenketsu and shut them down. After her observations were complete, Hikatoko began training herself how to use the Gentle Fist, focusing her celestial energy into a singular point in her hands before releasing it as she delivers each strike. Over time, she learned how to use her legs as well, further refining the Gentle Fist and adding her own twists to it.
