Nemuri Kayama is a Pro Hero and faculty member at U.A. High School, who taught Modern Hero Art History.

Nemuri is a tall, curvaceous woman with sky blue eyes that tilted downward in the center and were framed by a set of rather long eyelashes. She had long, thick, spiky, dark purple hair, which was made up of layers of varying lengths, the longest ones reaching down below her waist. Her chin-length bangs were split into three sections: two swept to the sides and one over her face, going diagonally down to the left between her eyes. She also had a small beauty mark below her left eye, as well as red-painted nails.

When she became "Berserker Midnight", she undergoes an immense transformation, elevating her physical size way past normal limits into a towering, "jacked" body type. Her shoulders (deltoids), traps, and back are heavily emphasized. The chest and arms are packed with dense, oversized muscle groups. Exaggerated Thighs and Calves; her lower body matches the upper body's intensity, featuring deep muscle separation and massive quads. Deep Striations of the muscle tissue is drawn with a heavy focus on definition, showing shredded lines and separation between every muscle group. Pronounced Veins due to pop-out vascularity is commonly etched across the arms, legs, and abs to emphasize peak physical strain and the "berserk" rushing energy.

Midnight’s naturally tall and curvaceous frame would explode into massive, shredded proportions, becoming a Colossal Amazonian Physique. Her shoulders, back, and thighs would expand dramatically, ripping her dominant dominatrix-style hero costume to shreds.Vascular Definition: Highly pronounced veins would trace up her neck, across her dick, across her thighs, across her legs and down her colossal arms to indicate the intense rushing energy pumping through her body.

Aggressive Sedation turns her Somnambulist quirk (which releases a sleep-inducing aroma from her skin) would become hyper-charged. The massive increase in her body's surface area and metabolic rate would cause her to emit dense, overwhelming clouds of sleep gas.

During her years at U.A., Nemuri's hair was much shorter, having reached down to her chin. She also wore pink, rectangular-frame glasses, and painted her nails the exact same color. Her original Hero Costume was also much more revealing than her adult one, with her breasts being covered by black protective plates, along with only undergarments, which were covered with a brown utility belt that held her whip. She was otherwise completely bare aside from an unbuttoned, high-collared green trench coat. She also wore a double belt choker, black fingerless gloves with a silver ring in her palms, knee-high deep red boots with folded-over cuffs with silver accessories, and large, angular shades that are tinted purple, different from the mask she wore later on.

When disguised as "Kaori" on a mission to root out groups distributing Trigger at mixers, she wore a short blond wig, a light blue, cable-knit sweater that reaches mid-thigh, and dark purple leggings with light lavender diamond-shaped pattern on the outer sides. She also wore a white jacket and heels before taking them off for the mixer. Later on, she was revealed to wear an extremely skimpy leotard underneath that matches her leggings.

Her adult Hero Costume was remarkably similar to one of a traditional dominatrix. She wore a breastless, black leather leotard—similar in style to a corset—over a thin, skin-tight, white bodysuit (flesh-colored in the manga), which accentuated her voluptuous figure. The center strip of her leotard was embellished with red gemstone-like accessories in a vertical pattern, extending from her collar to her midriff. She also wore light purple, thigh-high garter stockings, which were attached to a burgundy utility belt decorated with gold studs around her hips, a matching pentagonal buckle in its center, and black stiletto knee-boots. She had a small red mask outlining her eyes, a pair of handcuffs on both her wrists, and was often seen carrying a flogger-style whip. The white bodysuit was made of thin material that is easily tearable, so she could more easily use her Quirk. Nemuri had stated in an interview that she was trying varied materials to find out what works while adhering to costume regulations. In My Hero Academia: Vigilantes (and briefly in Chapter 24), she was also shown wearing stud earrings, with the Vigilantes anime adaptation, and some colored artwork of its source material, also depicting her as wearing reddish-pink lipstick while working.

As a Berserker, her standard hero costume is shredded, torn, or stretched to the absolute limit to visually emphasize how rapidly and heavily her body has expanded. She's half naked as most of her costume is shredded of her muscular body leaving only her black leotard which acts like panties but couldn't contain her gigantic cock which looks like it could engulf an average man in thick, wideness, hardeness and size. Just like her massive deltoids, quads, and abs, the new anatomy would be rendered with exaggerated, pop-out vascularity and immense scale, reflecting the surging adrenaline and explosive blood flow pumping through her entire body. Her metal cuffs would be cracked, with one of them already broken but still cling tight to her muscular wrist. Her thigh-high garter stockings somehow survived, which is still attached to a burgundy utility belt decorated with gold studs around her hips. She uses that belt to lift her massive heavy dick like setting on a sofa. And Nemuri found her replscement belt, she would use it to wrap it around the tip of her dick, tightening hard while lifting up so it wouldn't flop around. This would increase her arousal and sometimes make her drool. The moment ahe founds a prey, she drops holding her dick and prepare to attack and dominant.

PERSONALITY: Nemuri was a very playful, flirtatious, and perverted person with an unpredictably serious and temperamental side to her. She got angry whenever someone interrupted her or insulted her, and, when it came to insults, she was especially sensitive about her age. While she deliberately adopted an "R-Rated" dominatrix motif for her Pro Hero persona, she maintained clear professional boundaries as an educator and referee. Nemuri held a deep admiration for the pure, uncorrupted spirit of youth. This was highlighted during the U.A. Sports Festival when she enthusiastically accepted Mashirao Ojiro and Nirengeki Shoda's requests to withdraw from the tournament. Rather than being driven by inappropriate desires (which could be wrongfully assumed due to how in the English dub she said their naivety literally "turned her on"), her decision was rooted in a profound appreciation for their earnest integrity and "youthful talk," validating their mature sportsmanship. She displayed this same non-sexual excitement toward Eijiro Kirishima and Tetsutetsu Tetsutetsu's display of chivalry later in the tournament.

When Class 1-A needed to decide on code names for their internship, Nemuri displayed her willingness to help her students by making sure they chose names that would represent themselves well. During the First Term Final Exams, Nemuri admitted to Minoru Mineta that she has a sadistic side and enjoys dominating others. She could be impressed with those who resort to genius plans, as Minoru amazed her using tactical thinking to defeat her by luring her out and leaving her trapped in place before passing the gate.

Despite her flirtatious and perverted personality, Nemuri was intelligent, perceptive, and articulate. For instance, in an interview, she logically explained the reasoning behind some Heroes having revealing costumes to make full use of their Quirks, thus leading to "sexy" costumes, and how her previous "scandalous" costumes single-handedly led to the institution of Hero Costume regulations. However, in response, Mt. Lady commented that Nemuri simply liked dressing the way she did for attention, and given her frequent posing while on TV or addressing the media, this in itself was quite likely.

As shown during her time prior to working at U.A., Nemuri was capable of putting her lascivious Hero persona to one side when off-duty. As a civilian, she was perfectly capable of presenting herself as an ordinary woman and displayed a caring, thoughtful, and even motherly side towards others. This was shown with her friendship and care towards Pop☆Step and her empathizing with Hina, despite the former's vigilantism and the latter's wrongdoings. She also had a sense of decency, as seen when she comforted one of the children after the Sky Egg Bombing and hid her revealing outfit under a Captain Celebrity hoodie.

While she tended to act bawdy and came off as a Hero who enjoyed the fame derived from her beauty and sex appeal, Nemuri was willing to fight and put her life on the front lines during the Paranormal Liberation War, and demonstrated that, despite her excessive vanity, she held the true bravery and spirit of a Hero. Similar to All Might and Shota Aizawa, she also believed in her students and their capabilities, acknowledging that all of them have what it takes to become great Heroes in the future. In her final moments, Nemuri informed Momo Yaoyorozu that classes 1-A and 1-B must sedate Gigantomachia if he could not be stopped by force alone, and encouraged her students to stop the behemoth's destruction, even if doing so broke the law, having trusted them to make the right call.

When she became the Berserker, her usual playful, seductive smile would be replaced by an intense, aggressive grin and sometimes she would drool due to how much arousal she's packing in. Emotionally, her seductive, playful teasing would warp into an imposing, hyper-dominant urge to conquer. Instead of gracefully putting enemies to sleep, she would mentally crave crushing them under sheer physical weight, acting like an unstoppable, muscle-bound warlord who demands absolute submission. The anatomical addition would visually serve as an extreme extension of her hyper-dominant, warlord-like presence. Her mental state—already flooded with euphoric rage—would treat it as a literal and symbolic display of total supremacy over the battlefield.

ABILITIES: Overall Abilities: As a Pro Hero and U.A. High School teacher, Nemuri was a highly tactful and formidable combatant. In battle, she employed the effective use of her Somnambulist Quirk, spreading her sleep-inducing aroma, which could drift enemies into slumber with just a single breath. Nemuri also used her costume and support gear to efficiently aid her Quirk. Despite only appearing as though it just fitted her dominatrix theme, her whips and fans were designed to pick up traces of her scent and launch it in any given direction, thus giving her Quirk more accuracy. This especially made her effective against enemies who rely on close-range attacks, as they would be rendered fast asleep without any sort of breathing device.

As seen during her First Term Final Exam battle, Nemuri enjoyed tormenting her opponents, which made her a frightening adversary to go against as well. However, her sadistic side was also a weakness, as an enemy could exploit it, so she would act less rationally. This was demonstrated when Minoru purposefully ran away from her in fright to lure her out into going after him, giving him the successful opportunity to trap her and pass the exam.

Acrobatics/Gymnastics: During the Paranormal Liberation War, Nemuri demonstrated some acrobatic ability, having quickly evaded attacks from some Paranormal Liberation Front soldiers before using her Quirk to put them to sleep.

Keen Intellect: Nemuri was very perceptive and intelligent when it came to combat, something made clear by her sagacious use of her risqué costume and support gear to maximize the effectiveness of her Quirk. This was also seen when she witnessed Hitoshi Shinso following his First Round in the Joint Training Battle, and noticed how he was replaying the fight in his head to try and produce ways to improve.

Modern Art Expertise: Nemuri taught high school modern art history, indicating she had a good amount of knowledge on the subject.

Espionage: Nemuri had proven to be skilled at espionage, being able to go undercover during a mixer event under the guise of a college student. During the mixer, she livened up the party while keeping an eye out for any suspicious behavior, soon finding out that Hina was the one responsible for drugging men's drinks with Trigger.

CLOSE-QUARTERS DOMINANCE & SHOCK-AND-AWE BRAWLING: Unstoppable Blitzing: She uses her massive calves and quads for explosive forward momentum, turning her entire body into a human battering ram. She ignores incoming attacks, relying on her hyper-dense muscle layers to absorb shock while she closes the distance.

Heavy-Handed Striking: Her punches and open-palm strikes mimic heavy-duty demolition tools. Instead of precise martial arts, she uses haymakers, hammer-fists, and clotheslines designed to shatter defenses, break armor, and smash targets directly into the ground.

HIGH-IMPACT POWER WRESTLING & SUBMISSION GRAPPLING: Dominant Pinning and Grounding: Because of her towering height and massive weight, her primary goal is to force opponents onto the ground where they lose mobility. She relies heavily on brutal chokeslams, powerbombs, and suplexes that utilize the full explosive power of her expanded upper body and core.

Inescapable Bearhugs and Holds: Once she catches an opponent, she uses her massive, striated arms to lock them in bone-crushing holds (like the "Warlord's Embrace"). This physically paralyzes the target while placing them in the immediate blast zone of her quirk.

BIOLOGICAL AREA-OF-EFFECT (AOE) TACTICAL PRESSURE: Pressurized Gas Detonations: She uses intense, full-body muscle contractions to forcefully pump the hyper-concentrated Somnambulist sleep gas out of her pores. She deliberately builds up physical tension during a grapple, then releases a localized shockwave of sedative mist to instantly sap the stamina of anyone nearby.

Weaponized Positioning: Her combat style is inherently psychological and predatory. She intentionally positions her towering frame, hyper-vascular muscles, and fully exposed, mutated lower anatomy directly over pinned opponents. This tactical display of raw, hyper-dominant supremacy is used as a psychological weapon to break an enemy's fighting spirit and deflate quirks fueled by willpower or stress.

QUIRK: Somnambulist: Nemuri's Quirk allowed her to put nearby people to sleep by exuding a sleep-inducing aroma from her body. Her Quirk worked better on males than females.

EQUIPMENT: Whips of Love: Fitting her dominatrix theme, Midnight wielded a flogger-style whip in combat, and she was skilled in wielding it. She also used a bullwhip-style whip during the First Term Final Exam.

Feather Fan: Midnight used a pair of hand fans in combat to better spread her sleep-inducing fragrance.

Ultra Thin Fabric Suit: Nemuri could only spread her sleep inducing aroma from exposed skin. The law states that a hero costume can't expose too much skin, so to make up for this hindrance, she wore a suit made of a material that she could easily rip through.

High Density Weights (Final Exams Arc): Midnight and the rest of the teachers used these bracelets to give themselves a handicap while they were fighting their students.
