Mirai Sarutobi

is a kunoichi of Konohagakure's Sarutobi clan.

Background
Mirai is the child of Kurenai Yūhi and Asuma Sarutobi, born in the depths of Autumn. While growing up, she was watched over regularly by Shikamaru Nara, as it was his final promise to Mirai's late father. During which, Mirai became very close to Shikamaru.

Personality
As a two-year-old toddler, Mirai was outgoing and friendly to her parents' students, showing a special liking to Shikamaru, hugging him upon seeing him and referring to him as her big brother. She also had a penchant for giving others nicknames: calling Akamaru and Kiba a mixture of both their names for example. As a kunoichi, Mirai is cheerful, energetic and dutiful in carrying out any directive given to her. Though she did not know her father — Asuma having died before she was born — she appears to hold him in high regard as she was seen paying her respects to a framed photograph of him before leaving for a mission. She also felt it was her duty to make both her father and Shikamaru Nara, her father's student, proud because of how both of them had faith in her, and was deeply honoured to have her father's chakra blades passed down to her.

Both Naruto Uzumaki and Kakashi Hatake remarked that Mirai took her responsibilities too seriously, much like her father was when he was younger. She also began to have doubts about her duties as a shinobi during her mission to escort Kakashi and Might Guy because of how peaceful the world was, and disheartened at how neither Kakashi nor Guy seem to live up to their legendary statuses.

She also seems to enjoy challenges, as she hoped her escort mission would be an S-rank, and that attackers tried to confront her during her escort mission, but became horrified to learn that it was simply an excuse to allow Kakashi and Guy to take a vacation, which also caused her to have doubts of her own abilities, thinking that she was assigned to this mission because she wasn't skilled enough for more dangerous ones.

However, after being informed by Kakashi that the reason for Naruto personally hand-picking her for escorting him and Guy, was because Naruto was concerned for Mirai because she was too stiff on her responsibilities, and was hoping that she'd be able to loosen up and enjoy herself, and while Mirai still wanted to take her duties seriously, was finally able to relax and enjoy herself during her mission. She also seemed to have an enormous desire to meet her father, such as after initially turning down Tatsumi's request to heading towards a hotspring where people can meet with the dead, she accepts it after Tatsumi explained how the dead were revived during the Fourth Shinobi World War, and was tempted about the possibility of meeting her father.

Appearance
As an infant, she wore a simple yellow kimono with blue trimmings, held closed by a white sash. At two, her hair grew a significant amount and has a short ponytail tied above her head. Mirai wore a tan outfit with lighter tan colour stripe trimmings wrapped around her outfit, in a similar manner of how her mother wore her previous outfit. She also wears pink shinobi sandals.

As a young adult, her black hair is long and unruly and she has red, ringed irides — both of which she inherited from her mother, while for the most part she strongly resembles her father having inherited the shape of his face and his features. She wears the standard attire of the Konoha-nin inclusive of a green flack jacket over a black jumper and forehead protector. Some time later her outfit would change somewhat: she now wears a high-collared, long-sleeved outfit with a flack jacket that has button down lapels. She also wears shorts, sandals and an armband with the Sarutobi crest emblazoned on it.

Abilities
Mirai is a capable kunoichi, whose regarded as an expert personal bodyguard, from her acts of frequently escorting the Seventh Hokage. Senior shinobi hold her in high regards, and as such, she was chosen to protect the Sixth Hokage.

Ninjutsu
Mirai can use her father's signature Flying Swallow technique. She can use Fire Release to create a pillar of fire out of a small spark, and with Wind Release, use long-range techniques taught by Temari.

Genjutsu
Mirai's shown to have a talent with genjutsu which she inherited from her mother. She is able to use Demonic Illusion: Tree Binding Death, and it was powerful enough to bind the Sharingan-using Sarada Uchiha despite the dōjutsu's capabilities with illusions.

Physical Prowess
Like her late father, Mirai prefers to fight at close-range, using her heirloom chakra blades to aid her in battle. She has shown great proficiency in physical combat, as Sarada's Sharingan was unable to find any actual weak points in her battle tactics. She is able to skillfully fight off multiple foes at once and simultaneously strike at them with each of her limbs.

She has also pulled Akamaru's ears, with the latter surprisingly tamed. Later, she attends Hinata and Naruto Uzumaki's wedding alongside her mother, where she gave the bride flowers.

New Era
During her childhood, Mirai visited her father's grave countless times. Being acquainted with Shikadai Nara since his birth, Mirai developed a sibling-like relationship with him since they both were being trained by his father Shikamaru Nara. She would regularly use Shikadai to experiment and improve on her genjutsu. Following graduating from the Academy, Shikamaru became her sensei, during which she became an amazing ninja under his teachings. Once he had shown her something, she’d mastered it in a few attempts.

When Shikadai entered the Academy, Mirai supervised his training, with her goal to pass techniques that Shikamaru had taught to her onto Shikadai. At some point she participated in the Chūnin Exams, where she became a chūnin. Straight after her promotion, she visited her father's grave to tell him of the news, where she encountered Shikamaru, who congratulated Mirai and handed her Asuma's chakra blades.

Graduation Exams Arc
In the anime, when Sarada Uchiha and Boruto Uzumaki were displeased with being put on the same genin team, they were given the option to make a formal request to the Seventh Hokage to be reassigned. During which, Naruto was in charge of a training session with the elite ninja of the village to better prepare for future attacks. Mirai was put in charge of making sure that no unauthorised individuals interrupted it. When the two genin came, Mirai refused to let them pass. Determined to be reassigned, Boruto and Sarada attacked. Despite being outnumbered, Mirai easily overcame their assault, exploiting their lack of synergy. When Mitsuki pointed out that the two were focusing too much on the other's actions, Sarada and Boruto readjusted themselves to better take advantage of the other's skill set while fight with their own individual style. Ultimately, they were able to knock Mirai off the bridge but Konohamaru saved her from falling by ensnaring her with a rope. Ultimately, the two unhappy genin found a new appreciation for each other and instead moved on to ask the Hokage to be rebranded as the new Team 7. Much to Mirai's annoyance however, the group forgot about her as they moved on to talk with the Hokage.

Byakuya Gang Arc
When the self-proclaimed noble thieves, the Byakuya Gang, began gaining support from several villagers in Konohagakure, the villagers began acting out against companies accused of corrupt actions. Mirai joined her fellow ninja in working to pacify the situation. Ultimately, it was discovered that several of the protesters were under genjutsu. Mirai helped in dispelling the genjutsu. This along with Naruto's speech was able to peacefully end the riots.
