This article, Yui Uchiha (AOTD), is currently under active construction by the author(s) of whom this article's property falls under.
Yui uchiha is the younger sister of Sakiko Uchiha and currently a Medical-nin for her team.
Yui was born 5 years after her sister, at age 2 she was kidnapped by an ANBU shinobi from Danzo's Root and subsequently rescued by her older sister. For most of her life she lived in Ryuko Village, So she never really knew her birth home that well. However despite that being the case she still kept the will of fire because of her older sister. When her Parents were Murdered by Obito Uchiha, she awakened her Sharingan and Wood Release It wouldn't be until after the 4th Shinobi World War when she desired more power. While her older Sister and Kintaro's Organization were off world, she realized that she needed more power to protect her loved ones. A group of young wayfaring Uchiha whom Kintaro commonly spoke and hung out with outside the village came into town as a favor for Kintaro, the reason they came to the village was to protect it while the Children of the Phoenix were away. She decided to ask them about gaining more power and about the Mangekyō Sharingan. She learned about it's cost and that having Senju or Uzumaki DNA can negate the blindness that comes with it. After revealing her purpose for asking and about her older sister the grop of Uchiha offered a way to awaken Mangekyō Sharingan through a ritual without actually killing someone close to you but it is highly risky and dangerous as it has a high fail rate and can cause severe mental damage if not performed correctly. In order to awaken Mangekyō with the ritual the performer of said ritual has to use the required Genjutsu through his or her own Mangekyō, this requirement was known as equal power exchange. Along with this only the Mangekyō's nature to surpass the sharingan in power of illusion manipulation can perform the ritual because the ritual involves displacing memories and manipulating physical sensations in the illusion to be near unrecognizable as such. Yui declared she understood the risks and went through the ritual in the end she had to Kill her own Sister in the illusion, this in turn awakened her Mangekyō Sharingan which broke the Illusion.
After the incident with Momoshiki she decided to practice using her abilities and try to obtain a summoning contract. Often training with her older sister and Kintaro she learned some unique and high level jutsu and discovered the abilities in both her left and right eyes and mastering their abilities. As of current she and the rest of her Family and Friends live in Konohagakure. As per law in Konoha, learning the Shadow Clone Technique would allow her to graduate the academy which she did after only a year in the academy.
Yui is a kind and cheerful person. She is deeply devoted to her friends and family holding her sister in high regard often getting annoyed and angry about others talking bad about Sakiko behind her back. She has a fascination with Cats and Parrots in particular. She also has a playful attitude since she often decorates her kunai similar to her best friend and teammate Hanabi Hyuga.
She takes more after her father having the black hair with blue tint typical of the Uchiha clan. She wears a single sleeved long zip up coat-like shirt showing her midsection under which she wears a pair of short leggings. She has her ninja pack on her right thigh and a pair of knee high shinobi sandals. She wears her forehead protector as a belt and her left arm is covered in shinobi wrappings under which is a summoning tattoo.
Chakra and Physical Prowess
Being an Uchiha-Senju hybrid like her sister she possesses a huge reserve of chakra, stamina, and power even for a Senju or Uchiha. It is also because of this that she doesn't suffer from the Mangekyō Sharingan's side effects. Like her sister she has an enhanced healing factor and posesses the Regeneration Ability.
Being a member of the Senju Clan she possesses the Wood Release Kekkei Genkai. She like most Uchiha have an affinity with Fire Release. Above all else though is her potential ability to use all basic natures and possibly any combined nature Kekkei Genkai with her Right Mangekyō's ability. She can easily use all 5 nature transformations as a result of extensive training. Being the only known Uchiha with this potential she is regarded by all whom meet her as a potential threat or a natural-born prodigy.
As an Uchiha, Yui is very adept in the use of ninja tools. Her main weapon of choice is often either a Tantō or a Hand-Made gunbai made of spirit tree wood that Kintaro gave her as a gift.
Space Time Ninjutsu
Being one of the few Users of the Flying Thunder God Technique, Yui is adept at manipulating this in tandem with other techniques similar to Kintaro.
Yui Uchiha managed to achieve sage mode with the Power of her left eye, Omoikane. With this she can passively use senjutsu and possibly maintain and control it indefinitely. She often uses this in tandem with her right eye's ability, Ōkuninushi. Her sage mode is identical to Hashirama's due to her lineage and self taught use.
Yui is quite knowledgable in Fūinjutsu being able to create chains of chakra and use special seals.
With her Sharingan, Yui is granted enhanced perception and genjutsu abilities. She is skilled enough that she can use Medical Genjutsu with little effort. She has managed to master a few jutsu including the Rasengan and Chidori by applying visual focus with her Sharingan.
Yui is efficient at using several different Kekkei Genkai Techniques as a result of her right eye's ability. With her left eye she mastered sage mode. As an Uchiha whom awakened both her Mangekyō she can use Susanoo. Her Susanoo is a pure White color with red eyes and resembles Hagoromo Otsutsuki's Susanoo in its Complete-Body form. Because she is half Senju she does not suffer the Mangekyō Sharingan's side-effects. When she uses both her eyes' abilities at once she gains access to 2 to 5 Truth-Seeking Balls. Unlike others with her right eye's abilities, she can continually use it without a cool-down time as long as she has enough chakra to do so. This is also due to her Half-Senju Lineage.
