The bandits ended up offering the young girl to Orochimaru. Telling them that he quit his old, they desided to go elsewhere. Seeing that they wanted to enslave the girl, Orochimaru dispatched of them before taking the girl in as his daughter. After years of raising her, she would prove to be a very capable shinobi. After becoming an adult, Yosōi was enlightened of the true concerning her past by Orochimaru. Accepting this, she couldn't just leave him and, as they were all the family she knew. After thinking about it for some time, would make it her goal to find her biological family.

Background
Yosoi was enrolled in a while after she was taken in by Orochimaru. She excelled in the academy and would begin using her dojutsu abilities in front of others. One day, she began manipulating her own blood, which caused quite a ruckus at school. Upon finding this out, Orochimaru began training her in the use of her dojutsu, while forbidding her from using it at the academy. As a result of the incident at the academy, she was regarded as weird and a social outcast, much like. A year afterwards, she was withdraw from the academy and personally trained by Orochimaru and, whom she began to view as a brother.

Seeing this, Orochimaru would introduce her to, whom would go on to teach her the ways of the. After becoming quite feirce in kenjutsu, she would go on to become an. During this time, she would earn the moniker Tenchiame (天血雨, Heavens Blood Rain). Seeing how powerful she had grown, Orochimaru feared her abilities would get the best of her and corrupt her like it once did a of his. To help Yosoi, Orochimaru created a unique eyepatch designed to restrict the power of her Kerryūgan while still allowing her to see through it. He stated that with it removed, her power it increased at least a dozen times that of a normally proficient Kerryūgan wielder.

Personality
A very vigilant, yet determined young woman. That is how most would describe Yosoi. He devotion to people and causes she believe in are so absolute that none can turn her from them, as seen when thugs tried to attack, a confrontation that ended badly for the bandits. Despite this, Yosoi wasn't always as devoted to her beliefs as she is today. As a little girl, she was often seen as sweet, kind and very loving by her mother. Once she entered the academy and was exposed to the unpredictable situations in early childhood, she began to see that life as a young girl wasn't all tulips and roses. Having been bullied by other girls during her first few days, she would try her best to shrug it off. Her deep, blood stained eyes seemed to be the source of all her problems, at least to other kids as they would often throw dirt in her face in an attempt to damage them. After several incidents of academy teachers helping her wash dirt from her eyes, she tried to overcome the feeling of guilt and rejection by wearing tinted shades. While this helped for a while, it didn't stop others from resorting to more physical and emotional alternatives, like throwing rocks and talking about her appearance and parents. In all honestly, had they known that orochimaru was her father, they would think twice before talking about her out of sheer fear. While her confidence within herself dwindled, and her hate towards those who were against her grew, the hate directed at her grew to even greater heights. One day, a group of girls pushed her down and broke her shades, before kicking and punching her. After managing to get up once more, they pushed her again, causing her to fall and cut her leg on a rock. Looking done at her leg, she along with the other girls noticed that she wasn't bleeding like normal. Her blood appeared to be floating away from her wound. This was merely a sign of shock going through Yosoi's system as she gains lead on the situation. The blood would suddenly fall to the ground. After a short scream, Yosoi grew anger at the young guys as she pushed her arm forward. With that swift movement, Yosoi threw the girls back a great distance, while one of them flew into a tree.

Yosoi is noted of having unique blood in that foreign, outside, and synthetic medicines, drugs and chemicals are unable to coagulate her blood and she is also immune to. She uses this to her advantage in certain situations, allowing her to increase her already kage level control over her blood to unfathomable levels. She has also displayed the ability to fly by pushing herself away from the earths iron core through use of her kekkei genkai, granting her the ability of flight.

Yosoi possesses exceptionally powerful Kerryūgan, and as a result, her eyes are always a deep crimson red, and indistinguishable from her activated dojutsu. Orochimaru determined that it was several times as powerful as a normal Kerryūgan. This was further displayed during an Anbu mission when she controlled the movements of a troop of twenty plus shinobi by manipulating their blood. She then proceeded to dispatch of them all in an instant by making the blood within their body flow in reverse, a feat in itself. After realizing the potential of her dojutsu, Yosoi began to manipulate, and using it in conjunction with her blood based abilities. She is capable of completely halting the effects of poison and such by expelling the affected blood through her skin and out of the body.
