Where Is Midnight My Hero Academia First Introduced In Manga?

Midnight is one of those characters in 'Boku no Hero Academia' who instantly grabs attention, not just because of her risqué costume but also her bold personality. She's a Pro Hero and a teacher at U.A. High, specializing in art history and modern hero art. Her Quirk, 'Somnambulist,' lets her release a sleep-inducing aroma from her skin—super useful for subduing villains without a fight. But what really makes her stand out is her unapologetic embrace of her sexuality, which ruffles feathers but also challenges the series' often rigid views on heroism. I love how she balances being both a mentor and a provocateur. Like, she’s strict with her students but also encourages them to express themselves, even if it’s through wild costume designs. Her dynamic with other teachers, especially Eraserhead’s deadpan reactions to her antics, adds so much humor to the show. It’s a shame she doesn’t get more screen time, but when she does, she steals the scene.

Wow, that chapter hit me in the chest — Nemuri Kayama, better known as Midnight, does die in the manga. It’s revealed in chapter 345 of 'My Hero Academia'. The scene is heartbreakingly quiet for a few panels, which makes the impact worse; you get this weird stillness after all the chaos that precedes it. Her quirk, Somnambulist, and her whole personality come back into focus as she makes her final stand, and it feels like the story is asking you to remember the warmth she brought amid the darkness. I’m still blown away by how the author staged it: the artwork leans on expression and small gestures rather than a huge explosion. For longtime readers it lands like a punch and shapes a lot of the emotional fallout for the heroes that follow. Even weeks after reading it, I keep thinking about the quieter moments in her panels — the way her smile reads at the end. It really stuck with me.

I get why you're asking — Midnight (Nemuri Kayama) is one of those characters who feels like she should pop up everywhere in 'My Hero Academia', but the movies treat faculty pretty differently than the TV series. From what I recall watching the theatrical films, Midnight doesn't have any major starring moments in the big screen adaptations. The movies usually focus on the students or introduce new movie-only villains and heroes, and the pro heroes who get screentime tend to be the heavy-hitters like All Might, Endeavor, Hawks, etc. That means teachers like Midnight are more likely to show up as background or in group shots during ceremonies or press scenes, rather than getting a dedicated scene or combat moment. I, for one, always scan crowd shots hoping to spot little cameos — it’s a fun game — but I wouldn’t expect substantial character development for her in the films. If you want to be absolutely sure, check the movie credits or a reliable cast list (Anime News Network, MyAnimeList, or the official Blu-ray booklet). Fans also timestamp cameo appearances in forum threads and clips on YouTube, so that’s where I usually verify a quick sighting instead of relying on memory alone. Either way, if you want more Midnight stuff, the TV seasons and certain OVAs give her a lot more presence and personality than the movies tend to allow.

Crazy to think this is something people still ask, but here's the deal: no, Midnight does not die in the manga. During the huge hero-vs.-villain clashes in the Paranormal Liberation War and the later Final War sequences, she takes a brutal hit and is left critically wounded and out of commission for a while. The scenes are grim — lots of pro heroes pay a heavy price — and at first the severity makes it feel like anything could happen. That uncertainty is what fuels the rumor mill. What comforts me is that the story never writes her off permanently. She's shown being treated and her fate is clearly survival rather than a confirmed death. The anime, which follows the manga's lead, likewise doesn't kill her off in its adaptations up through the arcs that have been animated. I still get goosebumps thinking about how fragile the pro hero world is in 'My Hero Academia', and Midnight's injuries are a stark reminder of that — a heartbreaking beat but not a final curtain for her, which I appreciate.

Late-night rewatch sessions have made me really appreciate how Midnight cuts through scenes with both camp and gravity. One of the most iconic moments for her in 'My Hero Academia' is her theatrical teacher-introduction bits — the way she strolls into a classroom, full of wink-and-flourish energy, and then casually demonstrates her Quirk. It’s equal parts showbiz and pedagogy: the perfume-based Somnambulist is played for cheeky humor, but the animation frames it like a stage performance, complete with dramatically timed close-ups and music that sells her charisma. Beyond the playful exterior, my favorite Midnight scenes are the quieter, more grounded beats where you see the responsibility underneath. Whether she’s overseeing exams, protecting students behind the scenes, or standing alongside the other pros during a crisis, those shots of her shifting from playful to resolute really land. The contrast — glittery costume and serious eyes — makes her stakes feel real. I often find myself pausing on scenes where the camera holds her face while chaos happens elsewhere; it’s in those moments the show hints at a deeper professionalism and vulnerability. If you cosplay or fan-art, those two sides are gold: the theatrical wink for photos, and the solemn profile for more dramatic pieces. For me Midnight works best when the series lets both aspects breathe, and those blended scenes are what I always look forward to.
