TL;DR: Noblesse character guide, checked against AniList's character database rather than a fan wiki. Rai and Frankenstein, the human trio at Ye Ran High School, the RK squad of modified humans, the young Nobles and clan elders, and Dr. Crombel's Union, plus two corrections to this site's own earlier Noblesse coverage.
Search "Noblesse characters" and the results are thin. A Fandom wiki gets updated whenever an editor feels like it. Wikipedia's own Noblesse (manhwa) entry names five people and stops there.
This site's own Noblesse review profiles six characters in a single section, useful for a verdict, not built to double as a roster. The Noblesse reading guide maps the five arc phases but stays just as light on names. Tao, Takeo, Gejutel Landegre, Rajak Kertia, and the Union's Dr. Crombel go unmentioned or unexplained across both pages.
This guide profiles the cast AniList's character database confirms for Noblesse's manga entry (media ID 59983), cross-checked against Wikipedia and the official WEBTOON page rather than pulled from a wiki someone edited a decade ago. Two corrections come up doing that work: Noblesse ran 544 chapters, not 543, and the series concluded in January 2019, not December 2019, per both AniList's end date and Wikipedia's own account of the serialization. Small gaps, but they're the kind that compound when nobody rechecks the primary source.
Key Takeaways
- Noblesse ran 544 chapters on Naver Webtoon and WEBTOON, completing in January 2019 after roughly twelve years of serialization, per AniList and Wikipedia.
- Cadis Etrama di Raizel, called Rai, is the Noblesse title-holder; Frankenstein is his devoted servant and the principal of Ye Ran High School.
- The RK squad, Tao, Takeo, and M-21, are modified humans who defected from the Union and now live under Frankenstein's roof.
- Regis K. Landegre and Seira J. Loyard are the young Nobles who join the human cast at school; Gejutel and Rajak Kertia represent the older Noble generation.
- Dr. Crombel, the Union scientist behind the human-experimentation program, is the figure AniList's database most consistently names as an antagonist.
- Every name in this guide traces to AniList's character list for Noblesse, checked against confirmed first-appearance chapters rather than assumed from a fan wiki.
Overview
Noblesse's cast is deceptively large for a series that spends its first hundred chapters inside one high school. AniList's character list for the manga entry names more than two dozen figures with enough biographical detail to describe accurately: the school-arc trio, the RK squad, the young Noble contingent, the older clan leaders, and the Union's experiments and elders. This guide doesn't try to catalogue every extra who shows up for a single arc. It sticks to the names AniList's crowdsourced database has actually written up.
That status matters for readers coming from manhwa like Noblesse looking for a similarly large ensemble: Noblesse's cast rewards the same patience the picks on that list do, but the series is done. All 544 chapters are already on the record, which means every character below has a fixed, final story rather than an open one. For a wider view of series that finished the same way, best completed manhwa tracks what else has a real ending.
Noblesse Character Guide: Rai, the Series Protagonist
Advertisement
Cadis Etrama di Raizel, called Rai, holds a rank Wikipedia's own entry describes as a special title that "distinguishes him from all other Nobles": the Noblesse. AniList's character bio keeps the introduction simple. He wakes from an 820-year slumber in an abandoned South Korean building with no working knowledge of the century he's woken into, looks at what people on the street are wearing, and puts on the nearest thing that resembles it, a Ye Ran High School uniform. He follows the students in, and Frankenstein, who runs the school, finds his master sitting in the principal's office.
That's the whole premise, and AniList's bio is honest about what it's there for. Rai's confusion with modern technology, his fondness for ramen, and his general bewilderment at 21st-century Korea are the manhwa's comic relief, not an afterthought bolted onto a serious story. For the mechanics behind the Noblesse title, what it costs Rai to use his full power, and how the role differs from the ruling Noble Lord, the Noblesse review covers that ground in more depth than a character guide needs to.
Frankenstein and the Human Circle at Ye Ran High School
Frankenstein has served Rai for centuries and makes no secret of it. AniList's bio calls him the "father" of human modification and enchantment, credentials that sit oddly next to his day job running Ye Ran High School as its principal, a cover identity he built during the 820 years his master was asleep. He's the series' most expressive character by a wide margin: cheerful and theatrical around the human students, calculating and occasionally sadistic once a real fight starts. Some of his power was sealed by Rai after he misused it in the past. The seal comes off after Rai wakes, which is part of why Frankenstein's full-strength appearances register as events rather than routine.
The three humans who anchor the school-arc cast are Shin-Woo Han, Ik-Han Woo, and Yuna Suh. Shin-Woo is the first to befriend Rai, an athletic Tae Kwon Do and Hapkido practitioner with a reputation local gangs already respect before Rai ever shows up. Ik-Han is the group's hacker, skilled enough to match Tao, the RK squad's own tech specialist, and the source of a running joke about height once Regis, a Noble roughly his size, joins the class. Yuna is Shin-Woo's long-standing, unrequited crush and the calmer presence in a friend group that spends an unreasonable amount of its time being rescued from things it doesn't understand.
Su-I Im, an idol classmate AniList's bio places at chapter 94, and her acquaintance Hansu Jung round out the human side of the cast with smaller, later roles. Neither changes the shape of the story, but both are named, confirmed figures rather than background extras, which is more than most recap coverage of Noblesse bothers to check.
Son Jeho returned to the same hidden-power-in-a-school-setting premise years later, with faster pacing and a single protagonist instead of an ensemble. .

The RK Squad: M-21, Tao, and Takeo
M-21 is the RK squad's emotional center. AniList's dedicated character entry identifies him as one of the roughly hundred human subjects the Union experimented on under Dr. Crombel, labeled a failed result and used as a field agent until a mission alongside a close ally changed him. Rai does what the Union's own experiments couldn't and awakens M-21's actual power. From there, M-21 becomes fiercely, almost doggedly loyal to Rai, the RK squad, and the human students he was originally sent to surveil, chasing down the names and memories the Union's tests stripped from its subjects along the way.
Tao and Takeo are the other two names in the RK squad's founding trio, both modified humans from the Union's DA-5 unit under Dr. Aris. Tao, "Number One," is a genius-level hacker and programmer who now works Ye Ran High School's security desk as a day job, mundane cover for someone who can match a rival hacker move for move. Takeo, "Number Two," defected after learning the sister he'd been protecting through Union missions was a fabrication invented by Dr. Aris for her own amusement. Both now live at Frankenstein's residence alongside M-21 and have asked, more than once, for their own powers to be pushed further specifically to keep him safe.
M-24 is a fourth name that belongs in this section, even though his arc is genuinely hard to condense cleanly. AniList's bio ties him tightly to M-21, an early Union experiment who becomes the closest thing M-21 has to a sibling, before the story complicates his fate in ways a roster guide has no business spoiling.

Noblesse Character Guide: The Young Nobles and Noble Elders
Regis K. Landegre and Seira J. Loyard are the two young Nobles who fold into the human cast at school, and AniList's bios treat them as a contrasting pair rather than interchangeable. Regis is proud almost to a fault, values manners and honor above nearly everything else, and gets pulled into Tao's group as its reluctant third member, RK No. 3, despite his misgivings about modified humans. Those misgivings soften once he watches M-21 put himself between danger and the children he's supposed to be surveilling.
Seira, by contrast, barely shows emotion, is the last surviving member of the Loyard clan and its leader by default, and wields a soul weapon called the Death Scythe. She and Regis share a mental connection close enough that each can sense whether the other is far away, unconscious, or worse.
Rael Kertia is the wider Noble cast's most openly hostile figure toward humans, Rajak's younger brother, and the holder of an "imperfect" soul weapon, Grandia, that he wasn't technically supposed to receive without being clan leader himself. He's also, per AniList's bio, prone to letting emotion override tactics mid-fight, a flaw that costs him more than once against opponents he underestimates.
Rajak, his older brother and the actual Kertia clan leader, is closer to Rael's opposite: disciplined, quietly loyal to the Noble Lord, and skilled enough with his own soul weapon, Kartas, to fight without ever revealing which of his projected copies is the real one.
Gejutel R. Landegre, Regis's grandfather, is one of the only clan leaders who didn't follow the Previous Lord into a five-century eternal sleep, which puts him in the unusual position of secretly guiding the current Lord, Erga Kenesis Di Raskreia, through decisions her own father used to make. Raskreia herself is stricter and more conventional than her father was, wields the soul weapon Ragnarok, and carries a grudge tied to a betrayal she initially, wrongly, pins on Rai. The Previous Lord, her father, gets the gentlest characterization AniList's database offers anyone in Lukedonia: warm, a little humorous, and fond enough of Rai that he wanted him to become the next Lord instead of Raskreia, a request Rai turned down every time it was asked.

Dr. Crombel and the Union: Noblesse's Antagonists
Every named antagonist in Noblesse traces back, directly or organizationally, to the Union, and AniList's database is clearest about one figure in particular: Dr. Crombel. He's the Union's top scientist for most of the story, later rising to the rank of the Union's 13th Elder, and the architect behind the human-experimentation program that produced M-21, M-24, and the rest of the roughly hundred subjects the Union labeled M-1 through M-100.
AniList's bio doesn't soften what that means. Suffering, mortality rate, and the basic rights of the people he experiments on register with him only as data. One in-story remark, credited to a character who's fought both men, puts Dr. Crombel's raw power on par with Frankenstein's, which is as close as this series gets to naming a single figure as its actual final threat.
Beneath Crombel sit two named enforcement units. DA-5, led by the cold, arrogant Krantz, includes Shark, a short-range specialist who takes open pleasure in killing, and Hammer, a weapons expert who leans on explosives and gas rather than raw combat. Krantz himself is the strongest of the group by a wide margin and is eventually defeated by Rai directly. Cerberus, the personal guard of the Union's 12th Elder, adds three more confirmed names: Taze, its captain and by far its strongest member; Lutai, the more talkative and less violent of the pair sent to Korea; and Yuizi, its only female member and the quietest of the three. None of them individually reshapes the plot. Each is a specific, sourced name rather than an unlabeled mook, which is the whole point of checking a database instead of writing from memory.

Step-by-Step
AniList's character bios don't attach a chapter number to every name in this guide, but where they do, the numbers line up into a rough order of introduction. This isn't a reading order; the Noblesse reading guide already covers that by arc. It's the order this specific cast actually shows up, sourced from the first-appearance chapters AniList's own bios record.
1. Rai and Frankenstein: chapter 1. Rai wakes from his 820-year slumber and enrolls at Ye Ran High School; Frankenstein is revealed as the school's principal in the same opening stretch.
2. Shin-Woo, Ik-Han, and Yuna: early chapters. The human trio meets Rai on his first day and becomes the series' recurring school-arc cast.
3. Mary of the Union's Assassination Squad: chapter 30, per AniList's bio, the earliest confirmed antagonist appearance in the named cast.
4. Su-I Im and Hansu Jung: chapter 94. The idol classmate and her acquaintance join the human side of the story.
5. The DA-5 unit, Krantz, Shark, and Hammer: chapter 107. The Union's special forces team surfaces as a direct threat, with Tao and Takeo still embedded inside it at this point in the story.
6. Lutai and Yuizi of Cerberus: chapter 211. The 12th Elder's personal guard is introduced as the conflict widens past the DA-5 unit.
7. Taze, Cerberus's captain: chapter 231, confirmed by AniList as the strongest member of the unit.
8. The wider Noble cast: Regis, Seira, Gejutel, Rajak, and the Lord's court arrive once the story moves into the Noble homeland material, the stretch this site's reading guide places from roughly chapter 280 onward.
Tips for Tracking the Noblesse Cast
Group characters by organization, not just by name. Tao, Takeo, and M-21 all trace back to the Union's DA-5 unit before defecting; Krantz, Shark, Hammer, and Mary stayed. Knowing which side of that split a name belongs to answers most "wait, who is this again" moments faster than trying to remember every introduction individually.
Watch the soul weapon names. Rael's Grandia and Rajak's Kartas both take the form of twin daggers, a deliberate parallel AniList's bios mention independently for both brothers, and it's easy to attribute one brother's fight to the other if you're skimming. Seira's Death Scythe and the Lord's Ragnarok are distinct enough not to cause the same confusion.
Don't assume every RK-squad member started as an ally. Regis is a Noble recruited into the group against his own instincts, not a modified human like Tao, Takeo, and M-21. The four share a codename system, RK No. 1 through 4, but very different origins.
If a name shows up once in this guide and never again, that's expected. AniList's database for a 544-chapter series covers the figures with enough community attention to get written up properly, not every extra who appears for a single fight scene.
Common Character Mix-Ups
Advertisement
M-21 and M-24 are two different people, not typo variants of each other. Both are early, low-numbered entries among the Union's roughly hundred human experiments, both share a close bond specifically because they're among the few survivors from that original batch, and the numerical naming convention makes them genuinely easy to confuse on the page if you're reading fast.
Rael Kertia and Rajak Kertia are brothers, not the same person under two spellings. Rajak is the clan leader; Rael, despite holding a soul weapon of his own, isn't, and the story treats that discrepancy as a real source of tension between them rather than a detail to gloss over.
"Rai," "Raizel," and "Cadis Etrama di Raizel" all refer to the protagonist. AniList's structured name field stores the full form; the review and reading guide on this site, like most fan coverage, default to "Rai" for everyday reference. This guide does the same, reserving the full name for formal introductions.
The Union's Dr. Aris and Dr. Crombel are not the same character, though both hold research authority within the organization and both appear across multiple modified-human origin stories. Aris is tied specifically to the DA-5 unit's creation and Takeo's fabricated-sister storyline; Crombel operates at a higher, Elder-level rank and is the figure AniList's own data most consistently frames as the story's actual antagonist.

Frequently Asked Questions
Who are the main characters in Noblesse?
Cadis Etrama di Raizel (Rai) and Frankenstein are AniList's only two "main" cast entries for Noblesse's manga. Beyond them, the most narratively significant supporting figures are the human trio Shin-Woo, Ik-Han, and Yuna, the RK squad of M-21, Tao, and Takeo, the young Nobles Regis and Seira, and the Union's Dr. Crombel.
How many chapters does Noblesse have, and is it finished?
544 chapters, per AniList, and yes, it's finished. The series ran on Naver Webtoon from December 2007 and concluded in January 2019, a run of roughly twelve years. That's a small but real correction to the 543-chapter and December 2019 figures that circulate on some fan pages, including in earlier coverage on this site.
Is M-21 the same character as M-24 in Noblesse?
No. They're two different people, both early, low-numbered subjects among the Union's roughly hundred human experiments, and both share a close bond specifically because they're among the few survivors from that original group. The similar numbering makes them easy to mix up while reading quickly, but AniList's database tracks them as separate, distinct characters.
Who is Dr. Crombel in Noblesse?
Dr. Crombel is the Union's top scientist for most of the story and later rises to become its 13th Elder. AniList's bio credits him as the architect of the human-experimentation program that created M-21, M-24, and the Union's other modified-human subjects, and one in-story remark puts his raw power on par with Frankenstein's.
What is the RK Squad in Noblesse?
RK stands for Rai's Knights, the group Tao forms with himself as Number One, Takeo as Number Two, and M-21 as Number Four. Regis, a young Noble, is later folded in as the reluctant RK No. 3, making the group's four members a mix of defected Union experiments and an actual Noble.
Who is Frankenstein's master in Noblesse?
Rai, Cadis Etrama di Raizel, is the master Frankenstein has served for centuries, and Frankenstein calls him exactly that throughout the series. Frankenstein's own public identity, the principal of Ye Ran High School, is the cover he built during Rai's 820-year slumber, and the loyalty AniList's bio describes runs whole-heartedly in one direction: toward Rai.
Is this Noblesse character guide based on the manhwa or the anime?
The manhwa. Every name in this guide traces back to AniList's character database for the Noblesse manga entry (media ID 59983), not the 2020 Production I.G TV series, which covers roughly the first quarter of the story and introduces a much smaller slice of this cast.
