Tokihakiri Taisei

Tokihakiri Taisei (土圭体制) is a former kunoichi and current gunslinger from Getsugakure. After an experiment gone horribly wrong, she was pulled into a timeless void, where she remained for five of her years. Though five years passed in the void, in the outside world, only a week had passed. Finally escaping from the void, she found herself in the Westling Lands. During this time, she learned of the firearms they had created and decided to learn more about them. She found out her pocketwatch, and her body, had been absorbing the energies within the void, drastically altering her appearance. By siphoning some energy from the watch, she created two flintlock weapons; Ikkoku, a rifle, and Toki, a pistol.

Background
Tokihakiri had humble beginnings, growing up alongside her brother. They both went in the academy together at the same age. She managed to graduate at the same year as Kiritsu, at age ten. Though they were related, they were assigned to different teams. During their off time, Tokihakiri began experimenting with a seal to see what she could learn from it. This ended up turning horribly wrong, slowly pulling every fiber of her being into the invisible void. Crying tears of fear, she embraced Kiritsu before the void pulled her completely in. For the first while, she was scared, all alone inside the void that she was imprisoned in. But after a while, the void grew on her. Eventually, she began siphoning energy from the void, some of this energy going into her pocketwatch. For five of her years, she siphoned energy from the void, becoming more and more powerful each passing day. After five years had passed, she had enough power to break free from the void.

When she stepped out of the void, she found herself in the Westling Lands, a vast, technologically superior region of the world where every thing was high tech. Security systems, TVs and all manners of different tech surrounded the region. What caught her eye the most was the firearms. In awe of their design, she looked down at her pocketwatch and got an idea. Using the energy from her pocketwatch, she created two flintlock weapons; Ikkoku, a flintlock rifle, and Toki, a flintlock pistol. After a week in the Westling Lands, she sailed back east to a relatively unchanged Shinobi region. There, she met Sekiki and her brother Tamashi Kyanon in one of the villages. Noting they were gunslingers as well, she requested to join their side, understanding of their criminal lifestyle. The old her would have disagreed, but this new form of hers couldn't help but agree.
