Mirai Sasaki,[1] also known as Sir Nighteye, was a Pro Hero and Mirio Togata's mentor. He was also formerly a Sidekick to All Might, considered the brains behind him.[2]
Appearance#
Sir Nighteye was a tall, lean, muscular man with sharp and elongated features. His shiny hair was always worn, smoothed down, and parted to his left, and was dark green, with three yellow streaks towards the front, two on his right and one on his left. His eyebrows were also yellowish, matching the rims of the triangular glasses he wore and the strikingly bright yellow irises of his stern-looking eyes. His looks gave off a sense of authority and power, as he rarely smiled and looked stern, and he always appeared to be glaring.[3]
Unusually for a Pro Hero, Nighteye appeared to prefer plain office clothes; a plain white suit with gold buttons, a white dress shirt, and a red tie with white dots instead of an elaborate hero costume. His clothes, however, were quite durable, as he used them during battles, and they didn't show any sign of damage or tearing.
In the past, during his time as All Might's sidekick, Nighteye wore a dark blue suit with a simple yellow tie.
Personality#
Sir Nighteye maintained a stoic and intimidating presence with a cold and sharp glare, but that was only the side of his personality he showed in public. Even with his supposedly fierce stare, Nighteye greatly valued humor and required people to make him laugh before he acknowledged them. Nighteye believed that humor and energy were vital elements for the future of society and punished subordinates who failed to display those qualities. For example, he placed his sidekick Bubble Girl into a tickling device for failing to amuse him with a report.
Nighteye was a big fan of All Might, watching videos about his deeds and keeping many of his collectibles and merchandise. He was quickly able to recollect events and details of All Might's heroism from the past, and his knowledge regarding All Might even came on par with that of Izuku Midoriya's. All Might also attempted to shape Nighteye's vision of what a hero was supposed to represent: someone who instills fear in the heart of Villains through power and hope in the hearts of civilians through good humor. At the same time, Nighteye intensely cared for All Might and expressed grave concern when he would continue with his hero duties after receiving horrific injuries from his first battle with All For One. He pleaded with All Might to retire and focus on finding a successor, foreseeing that he would meet a horrible death should he continue serving as the Symbol of Peace.
Despite this, Nighteye strongly disapproved of All Might choosing a Quirkless Izuku Midoriya to be his successor and inherit One For All. He protested against this strongly, saying that there would be any number of people more suitable, and declared that Izuku could not become All Might's successor on good intentions and willpower alone, showing a far more pragmatic approach. This disagreement would lead to the hero and sidekick falling out and Nighteye focusing on finding a more worthy candidate despite All Might having made his decision. Though he appeared rather cold in some situations, he quickly jumped to the defense of his sidekicks and anyone who worked under him. He was quick and very open about when he made mistakes and defended other people who had made mistakes under his orders. Sir Nighteye was also highly brave and courageous, willing to face the highly powerful Overhaul just after he fused with Shin Nemoto and had managed to destroy Mirio Togata's Quirk. Nighteye soon expressed his rage towards the Yakuza, believing that Overhaul must have feared his protégé enough to use one of his precious Quirk-Destroying Drugs on him.
Nighteye had shown to fear using his Quirk to a large extent, particularly when it involved foreseeing an individual's future death, as he formerly believed that once he saw into the future, that future was set in motion and could not be changed. Because of this, Nighteye felt great fear and guilt over believing that his Quirk dictated the fates of other people, something that was demonstrated when he foresaw All Might's gruesome demise at the hands of All For One upon using his Quirk on the former, despite All Might having asked him not to, and later seeing Overhaul escaping with Eri and Izuku being killed during the Shie Hassaikai Raid.
However, this fatalistic mindset was changed shortly before his death when he witnessed Izuku defying his Quirk's vision during the raid, with Eri being saved and Overhaul defeated. While on his death bed after being mortally wounded by Overhaul, Nighteye hypothesized that everyone's wishes for a better future were able to change fate itself and admitted that he was wrong about Izuku. He also felt regret towards Mirio, expressing his pride towards his treasured pupil and guilt over only seeing him as a mere vessel for One For All at first. Using his Quirk one final time, Nighteye comforted Mirio and assured him that he would become an outstanding hero. Moments before he passed away, Nighteye smiled and encouraged those around him to do the same, saying that a world without smiles and humor has no bright future.
Abilities#
Overall Abilities: According to All Might, Sir Nighteye did not have any impressive physical abilities and acted more as a support for his intelligence. However, he was shown to be exceptionally fast and capable of throwing heavy projectiles, particularly his Hyper-Density Seals and tripping up enormous foes. Furthermore, under his suit, he sported an impressive physique, showing that he deliberately hid his physical prowess to catch opponents off-guard or had increased his physical prowess after falling out with All Might or combining the previous two factors.
During the Shie Hassaikai Raid, Nighteye was capable of easily tripping up a Kendo Rappa clone created by the villain Twice and then sending the clone flying with multiple Hyper-Density Seals before sending another seal to graze Twice. Shortly after, when Joi Irinaka's presence was exposed, Nighteye incapacitated the yakuza member with a single Density Seal. In what would subsequently be his last battle, Nighteye had enough mettle to take on Overhaul, the leader of the Shie Hassaikai, who had drastically increased his power through his fusion with Shin Nemoto. Nighteye used his Density Seals against the amalgamated Overhaul, but to no avail, and employed his Foresight to help him evade the majority of the yakuza leader's onslaught, only to eventually be fatally injured by the ground spikes the villain had reassembled.
Genius Intellect: Aside from his Quirk, Nighteye's abilities lay with his intellect. He acted as the brains for All Might during their partnership. Nighteye used his intelligence, sometimes in tandem with his Foresight, to devise strategies to tackle situations and ensure the best outcome could be achieved. When he first met Izuku, who was attempting an All Might impression, Nighteye pointed out the discrepancies in Izuku's impersonation of the retired Symbol of Peace. In All Might's younger days, his crow's feet were 0.6 centimeters long, whereas from the Silver Age to the present, the crow's feet have become 0.8 centimeters long. Nighteye noted how some unlicensed merchandise gets the correct wrinkles from the right era. After his 3-minute bout with Izuku, and the latter revealed he was trying to avoid stepping on the unreleased 10th anniversary All Might poster, Nighteye realized that, despite all of Izuku's consistent rebounds off of the walls and ceiling of the internship office, the One For All inheritor was doing his best to avoid damaging all of the prevalent All Might-based merchandise.
While venturing through the Shie Hassaikai Compound, wherein Joi Irinaka separated multiple heroes and police officers from one another, Nighteye suspected something was amiss. His suspicions were proven true when the villains Twice and Himiko Toga initiated coordinated surprise attacks on the separated crime fighters. After witnessing Twice and Himiko betray Joi, Nighteye correctly deduced that the League of Villains duo used the raiding team of heroes to take out the Shie Hassaikai. While confronting Overhaul and learning that Mirio Togata had lost his Permeation Quirk, Nighteye meticulously surmised that Hari Kurono took Eraser Head from the battlefield, and Overhaul was pressured into using one of the completed Quirk-Destroying Bullets on Mirio.
- Teaching Ability: Sir Nighteye's Hero tutoring skills were notable, as he converted the then underachieving Mirio into one of the most powerful students at U.A. High School in less than a year. According to Shota Aizawa, Mirio was probably the one closest to taking the No. 1 spot, and this assessment included fully-fledged Pro Heroes. Eight years after the Final War, this insight proved to be true, with Mirio soaring up the ranks and becoming Japan's No. 1 Hero.
Quirk#
Foresight: Mirai's Quirk allowed him to see another person's future from a third person's point of view. To activate his power, Mirai first touched the intended target and made eye contact with them. This Quirk stayed active for one hour, and once activated, it required 24 hours before it could be activated again.
While his Quirk was active, Mirai could see years into a person's future. The future he saw was shown in great detail (second by second), and it had always been 100% accurate, even when he tried to change the events he had foreseen.
However, it has been shown that Quirks that alter an object's flow of time in some way, such as Eri's Rewind, can affect the accuracy of Mirai's Quirk, rendering the predicted outcomes moot and void. An example of this was when a Rewind-affected Izuku Midoriya defied the initial prediction of him dying at the hands of Overhaul during their battle.
Ultimate Moves#

Stats#
Equipment#
Hyper-Density Seals: Sir Nighteye's preferred weapon; special seals that weigh 5 kilograms (11 pounds) each. He could throw those objects with great force and accuracy. He wielded them due to a humorous perception of what kind of weapon would best suit a salaryman.

Trivia#

- According to Sir Nighteye's Ultra Analysis profile:
- The yellow streaks in his hair served as a homage to All Might.

- Nighteye's surname is composed of the kanji for "help, aid" and "wood", the "々" being an iteration mark. His first name means "future", which is a reference to his Quirk.
- Nighteye's name and character could possibly be inspired by the DC Hero Dick Grayson, who was the sidekick of Batman under the name Robin, before parting ways with his mentor and donning his own hero name, Nightwing.
- In addition, the color scheme of Nighteye, yellow, green, and red, may be based upon the traditional coloring of Robin's costume.
- Nighteye owns several books about All Might. Some of them include:
- All Might's Path, Part I and II.
- Heart of a Hero.
- "I Am Here".
- All Might Photo Collection (2 copies).

- All Might's Wise Word.
- Nighteye's requirement to have people make him laugh at least once resembles the character King Kai from the Dragon Ball series.

- However, Nighteye genuinely cared about those around him and renounced his stubborn ways upon seeing Izuku's heroism, accepting him as One For All's rightful holder before passing away peacefully. Overhaul, on the other hand, only saw those around him as diseased or tools for him to use and refused to change his ways, causing him to lose everything, including his hands, his ability to use his Quirk, and the organization that he devoted his life to.
