Mirai Sasaki

Two meters of lean muscle, sharpened into angles. Nighteye's features were elongated and severe, and he kept his hair glossy and smoothed to his left, dark green, cut near the front by a trio of yellow streaks. His eyebrows carried the same yellow, matching both the rims of his triangular glasses and the bright irises behind them. He almost never smiled, and his resting expression sat somewhere near a glare.

Where most Pro Heroes reach for a costume, he dressed like a salaryman. A gold-buttoned white suit, a red tie flecked with pale dots, and a plain shirt beneath made up his working uniform, and he fought in it without the cloth ever tearing. In his sidekick years the suit was dark blue and the tie plain yellow.

The cold front was public performance. Humor mattered enormously to him, to the point that he required a laugh before acknowledging someone, and he held that comedy and energy were prerequisites for a society with any future. Staff who failed that standard were punished; Bubble Girl once ended up in a tickling device over a dull report.

His fandom for All Might was total, down to the merchandise and the archived footage. His mentor in turn shaped what he thought a hero was: someone who frightens villains through power and reassures civilians through good humor. After All Might came out of an opening clash against All For One badly wrecked, Nighteye pushed him toward retirement and a successor, having foreseen a gruesome end otherwise. The successor he got was a Quirkless middle schooler. Goodwill and grit were not enough, he argued, and the partnership broke over it.

Toward his own subordinates he was protective rather than harsh, quick to shield people who erred under his orders. Courage he had in quantity: he took on Overhaul directly after the yakuza fused with Shin Nemoto and destroyed Mirio's Quirk.

What he actually feared was his own Quirk. Seeing a death convinced him the death was locked in, and the guilt of feeling like the author of other people's fates weighed on him. Watching Izuku break that last prediction undid the fatalism. Dying of Overhaul's wounds, he suggested that a collective wish for something better can bend fate itself, and admitted he had misjudged both Izuku and Mirio. He spent his Quirk a final time to promise his student he would become a magnificent hero, then told the room to smile.

Foresight let him watch a chosen person's future from an outside vantage. Activating it meant touching the target and locking eyes; it ran for an hour, then locked him out for a full day. Within that window he could look years ahead, second by second, and what he saw had never once been wrong. The one known crack is temporal interference: Eri's Rewind altered Izuku enough to void the prediction of his death.

All Might rated him unremarkable physically, a support piece who contributed brains. That undersold him: he moved with real speed, and under the suit he was clearly built. His weapons were Hyper-Density Seals, office stamps of five kilograms apiece, chosen on the joke that stationery suits a salaryman, and he threw them hard enough to send a Kendo Rappa clone flying. Against the fused Overhaul they accomplished nothing, and reassembled ground spikes eventually ran him through.

The intellect was the real weapon. He ran All Might's strategy during their partnership and paired his Quirk with analysis to engineer outcomes. Meeting Izuku, he picked apart the boy's impression of the retired hero down to the crow's feet, measured at 0.6 centimeters in the early years against 0.8 later on. Inside the Shie Hassaikai compound he registered that the heroes being separated was deliberate, and once Twice and Himiko Toga turned on Joi Irinaka he worked out that the League had used the raiders to gut the yakuza.

Teaching was the legacy. He took an underachieving Mirio Togata and built him into arguably the strongest student at his school inside a year. Eight years past the war, Mirio held the top rank outright.
