Warning! Tropes and character descriptions will contain spoilers!
Main Characters (Twenty-Fifth Bam) | Organizations (FUG (Canines), Wolhaiksong) | Regulars (First Batch, Second Batch, Third Batch, Fourth Batch, Fifth Batch, Sixth Batch) | Rankers | Irregulars | Jahad Empire (Great Warriors, Princesses of Jahad, 13 Month Series) | Floor Guardians | Others
Rankers are people who have already climbed to the 134th Floor of the Tower, and are further split between normal Rankers and High Rankers, who achieved a high ranking even among them. In short, they are all pretty badass. Other than the main characters, Irregulars, members of the Jahad Empire, and Princesses of Jahad are largely Rankers as well, but are listed on their own pages.
- The Ageless: Climbing The Tower gives them eternal youth (with the exception of the Hendrock Family - they are... special). This immortality (more specifically greatly lengthened life spans) is a specific reward for passing a Floor near the very end, so some very high Regulars also fit in with this.
- Bunny-Ears Lawyer: All of them are kinda odd compared to the more normal Regulars, but as individual Rankers get focus it's shown to be more of a coping mechanism to deal with the trauma of climbing the Tower.
- Knight in Sour Armor: All of them that aren't outright evil are pretty world-weary with the current system. This is because, to climb the Tower, they had to abandon friendships and betray people for personal advancement.
- Older Than They Look: As Rankers who have climbed the Tower with the power to use Shinsu, they are all nigh immortal and much older than they look.
- Really 700 Years Old: Some border on Time Abyss.
Floor Rulers
A Ruler is the overlord of a given Floor, who gain their authority with the permission and consent of a Guardian. They officially act on the Guardian’s behalf in managing the execution of tests and apprehending threats to the Floor. Rulers have near-absolute power over their domain, subject only to the wishes of the Floor’s Guardian. Only those of a level equal to a High Ranker can become a Ruler, while the overwhelming majority of Rulers are members of the Ten Great Families or otherwise affiliated with the Jahad Empire. The various Rulers of the Tower may also hold a “Ruler’s Conference” overseen by the Three Lords.Evankhell
Tower Position: Wave Controller, Fisherman, Flame User
Rank: 60 (formerly); Top 300 (currently)
Occupation: Ruler of the 2nd Floor (formerly)
Sobriquet: The Infernal Evankhell
The Ruler of the Second Floor. Very strict and very tall, Evankhell has agreed to a complex testing system on the Second Floor for reasons unknown. Evankhell was just The Ghost in Season 1 only ever being mentioned in dialogue due to being on vacation from her 2nd Floor duties.
Hundreds of chapters later, Evankhell finally makes her on-screen appearance at the tail end of Season 2 to help Bam and his companions escape Jahad's forces at the last Hell Train station on the 44th Floor. In Season 3, Evankhell takes in Bam, and trains him up so that he can rescue Jinsung from the Nest complex. From there, Evankhell continues to support Bam's climb up the Tower.
- Asskicking Leads to Leadership: She gained her position as ruler of the Floor of Test by killing the previous ruler.
- Blood Knight: Considering how she got her job, it should come as no surprise that she loves to fight strong enemies. She was willing and able to take on two high rankers close to her level and an army of about 30 normal rankers at the same time without even using her full power.
- The Dreaded: Everyone speaks in a very respectful tone about her, and everyone fears what might happen if she finds out how screwy things went.
- The Ghost: For the entire 1st Season (despite it taking place on her floor), since she's on vacation. Only descriptions from Rankers allude to her history. Really, it was the only way for the plot to happen. If she was there half of the events would not have been able to occur.
- Gracefully Demoted: After the 2nd Floor Guardian fires her as the Ruler of the 2nd Floor, Evankhell drops out of the top 100 Rankers. She barely cared about either her job or her rank in the first place so it isn't really an issue.
- The Mentor: She takes Bam as her apprentice, for fun.
- Playing with Fire: Her elemental nature. The orb she created contained enough fire inside to become a small sun and nearly incinerated all the other combatants on the 44th Floor.
- Samus Is a Girl: Turns out to be a woman when she finally makes her appearance.
- Self-Made Woman: Evankhell doesn’t belong to any notable family and achieved her power through her own strength. Specifically, she killed the previous Ruler of the Second Floor and took their place.Evankhell: The problem with Jahad's Army is that they value family background too much. The kind of pathetic losers who care about social standing or class HAVE NO RIGHT TO STAND ON THE SAME BATTLEFIELD AS ME!
- Sink or Swim Mentor: Her idea of training Bam is to send him to appropriate battle locations. She selects the battlegrounds and forbids Bam from using the red thorn or Black March without her permission (to build his basic skills).
- Statuesque Stunner: Not bad looking and capable of shifting her size to be seven meters tall.
Khun Royale Elliot
Rank: High Ranker
Occupation: Ruler of the 44th Floor
Ruler of the 44th Floor, a Khun Family member that becomes involved with the Battle at the Last Station once his domain becomes a warzone.
- All-Powerful Bystander: Khun Royale Elliot is a fairly hands-off Ruler until you start a ruckus in his territory.
- Ambiguously Related: He shares a surname with Mad Dog Buelsar Elliot, but it's unclear whether they're related.
- An Ice Person: As expected from a son of Eduan. He can control ice on a large enough scale to match Evankhell using her full Ancient power.
- Elemental Rivalry: Played with. Khun Royale Elliot's power level means Evankhell marks him as the "Dangerous One" upon arrival on the Floor. Although she's itching to fight, Royale just wants Evankhell, the Jahad Army, and Bam and co. to get lost ASAP.
- Horned Humanoid: Royale has two skin-colored horns on his head.
- Modest Royalty: Most wouldn't expect a Floor Ruler to walk around in a sweatshirt and joggers.
- Punch-Clock Villain: He doesn't especially care whether the Army accomplishes their mission, but is more their ally than the Hell Train Regulars.
- We Have Reserves: Though ostensibly allied with the Jahad Army, once he gets involved in fighting Evankhell, he doesn't care at all who gets hurt in the crossfire. As a result, Elpathion is forced to spend half of the battle preventing the Floor from being decimated.
The Grand Family
The de facto Rulers of the 43rd Floor, following the destruction of the Floor and the Floor Guardian by Enryu. The family patriarchs of the Grand Family, De Sah and De Jah, were the only High Rankers to survive the decimation of the Floor, thrusting them into a position of power. They and the other survivors found refuge inside the deceased Guardian’s corpse, isolating them from the Death World the Floor had become. However, the hostile environment, the Jahad Empire’s massacre of those who tried to escape the Floor, and the survivors’ continued need for sustenance, meant the residents of the 43rd Floor were still endangered. To remedy this, De Sah and De Jah allied with Po Bidau Gustang to create the Spirit Room, a place that could store the souls of all the Floor’s residents, allowing them to live forever as The Needless without aging, but at the cost of being unable to leave the Floor. The brothers thereby became the leaders of the inhabitable portion of the Floor of Death, splitting it into North City and South City.
- Arch-Enemy: Hell Joe, who overthrew De Sah to forcibly obtain the means to regain his soul.
- Bait-and-Switch Tyrant: While it initially seems like the violent and power-hungry Hell Joe is the Tyrant to the Grands' Benevolent Mage Ruler, later events complicate this view. Hwaryun reveals that, in response to attempts by residents to regain their souls and leave the Floor, De Sah and De Jah would imprison the offenders and/or trap the corresponding souls in Shinheuh and dolls so they were forced to remain.
- The Fundamentalist: They will not tolerate anyone who acts against the Messenger of God, Enryu. As such they treat attempts to leave the 43rd Floor as an unforgivable sin.
- Holding Out for a Hero: Justified, as only an Irregular can wield the Thorn, but after several thousand years, they've latched onto the inevitable arrival of the savior as a matter of destiny.
- Motive Decay: They initially promised to only hold the souls of the 43rd Floor residents for 500 years. When the savior still failed to arrive, they began to forcibly subjugate anyone who tried to leave, quelling dissent by using the Soul-Stirring Ladle as the symbol of their divine mandate.
- The Needless: Removing a person's soul using the Soul-Stirring Ladle removes the need for sustenance and halts their aging.
- Soul Jar: The Spirit Room under their control holds the souls of every resident of the 43rd Floor.
- Stumbled Into the Plot: Their political power is the primary result of being among the few High Rankers to survive the aftermath of Enryu's rampage.Hwaryun: Most of the people who were on the Floor of Death died…. Those here were lucky enough to be surrounded by the Guardian’s body, isolating them from the instability of the Floor. But they still suffered from aging and a lack of food. Yet they couldn’t leave, because Jahad’s Army was slaughtering any survivors to silence the rumors surrounding Enryu.
- Touched by Vorlons: After looking upon Enryu, De Sah and De Jah's eyes were blessed with unique abilities.
- Villain with Good Publicity: Despite the cruelty they show to those who act against their rule, they've provided stability to the Floor of Death. As such, when He'll Joe was able to force a vote, the people still chose the Grands over the possibility of liberty.
- Well-Intentioned Extremist: They are unforgiving to anyone who interferes with their mission, but their intent is to avoid attention from the Jahad Empire in order to protect the Thorn until the foretold savior arrives.
Grand De Jah
Tower Position: Sorcerer
Rank: High Ranker
Occupation: Ruler of North City (former)
Co-creator of the Spirit Room and the former leader of North City. In exchange for a currently unknown favor, Grand De Jah gave his eyes, capable of seeing the future, to David Hockney.
- The Chooser of the One: Subverted. While Bam and Rachel were given the task of defeating Hell Joe to earn the Thorn fragment, neither succeeds. Gustang ends up giving the fragment to Bam in exchange for an entirely different favor.
- Detect Evil: When Rachel volunteers to compete with Bam for the Thorn fragment, De Jah initially refuses her due to a darkness sensed in her soul.
- Magical Eye: De Jah's eyes, as evidenced by his Exotic Eye Designs, have incredibly potent abilities.
- Out Gambit: De Jah, in an alliance with Garam Jahad, was able to repel an attempt by Hell Joe to overthrow his rule of North City.
- Seer: Looking upon Enryu gave his eyes the ability to see into the future to a limited degree. This power allowed him to foil Hell Joe's coup where De Sah failed.
- Soul Power: The creation of the Spirit Room required extensive spellwork in addition to the capacity to manipulate souls.
- Super-Empowering: On both sides, as De Jah was empowered with foresight by Enryu (possibly) and transferred the same ability to Hockney.
Grand De Sah
Tower Position: Sorcerer
Rank: High Ranker
Occupation: Ruler of South City (former)
Co-creator of the Spirit Room and the former leader of South City, who was ousted and imprisoned after a coup by Hell Joe.
- Artifact of Power: The Soul-Stirring Ladle that De Sah holds is the only known way to recover souls from the Spirit Room. Its ability to remove and manipulate souls makes it a coveted item even outside the Floor of Death.
- Belief Makes You Stupid: His obsessive belief in a perfect savior, combined with the Sunk Cost Fallacy, mean that he will likely keep his people trapped on the Floor of Death forever.Hwaryun: If the savior that you’ve been waiting for is someone who will overlook all your sins, that person isn’t here. Sorry.
De Sah: …Is that so? Then, I’ll just…have to keep waiting.
Hwaryun: …Sure. If you believe that is your destiny. - Hoist by His Own Petard: He's the one who hired a young Joe as a Hole repairman (Holes being the converted blood vessels of the 43rd Floor Guardian, used to carry its Shinsu-infused blood into the inner section of the Floor). De Sah's decision backfired when Joe used his influence to turn many of the residents of South City against the Grands.
- Locked in the Dungeon: De Sah has been imprisoned by Joe for years by the time Bam arrives.
- Magical Eye: Downplayed, he's said to have experienced the same Super-Empowering as De Jah, but lacks the latter's Seer capabilities, while the specifics of De Sah's powers remain unknown.
- No Man Should Have This Power: When Hell Joe's coup succeeded, De Sah ended up destroying Soul-Stirring Ladle to keep its power from Joe. It's later revealed that he faked this.
Grand De Lee
Tower Position: Scout, Circle Ability User
Rank: Ranker
Occupation: Ruler of North City
A younger member of the Grand Family and Grand De Jah’s chosen successor as leader of North City.
- Apologises a Lot: He begins begging forgiveness in the Pose of Supplication at the slightest inconvenience.
- Eerie Pale-Skinned Brunette: De Lee's pale skin and Monochromatic Eyes make him look more than a bit unsettling.
- Magical Eye: Like his relatives, De Lee has eye-based abilities, with his technique, "Sniper Eyes," giving him Super-Senses.
- No-Nonsense Nemesis: Upon realizing that Hwaryun is attempting to steal the Soul-Stirring Ladle, De Lee immediately tries to kill all her allies.
- Poisoned Weapons: His invisible observer, Little Bee, can inject a poison to kill his targets slowly and painfully.
- Strong Family Resemblance: Inverted. While De Sah and De Jah are obviously inhuman with fairly skeletal appearances, Grand De Lee (specifically when his pupils are visible) looks pretty normal.
Test Directors
A Test Director is a Ranker who decides test specifics in accordance with the authority granted by the Ruler of the Floor. They are responsible for supervising all the examinations that Regulars undergo on a Floor and coordinate procedure with their subordinates, the Test Admins.Yu Hansung
Voiced by: Daisuke Kishio (Japanese), Lucien Dodge (English)
Tower Position: Wave Controller, Anima, Cutter, Circle User
Rank: Advanced Ranker
Occupation: 2nd Floor Test Director (formerly)
The Test Admin of the Floor of Test, second in command to Evankhell. He is a genius in many ways, looks like a very attractive woman and is known among the Regulars for two things: His devious, scheming personality and his complete and utter addiction to instant coffee. He really likes any kind of instant food.
Yu Hansung also has a younger data version of himself within the Hidden Floor. His data self works alongside Bam and company in an attempt to escape from said Floor's data rulers.
- Agent Peacock: Dresses quite well, even when in casual. Always has fabulous hair.
- Almighty Janitor: Based on ability alone, he is shown to be as strong as a High Ranker, yet chooses to remain an Advanced Ranker for unknown reasons. His power is even said to surprise the Vice-Commander of RED.
- Badass Boast: His entire confrontation with Ren boils down to this.
- The Beastmaster: He is an Anima.
- Bitch in Sheep's Clothing: Appears to be a Reasonable Authority Figure at first. The reality is quite different.

- Curtains Match the Window: Yellow/Gold.
- Dude Looks Like a Lady: Very feminine looking, especially with his hair down.
- Foreshadowing: Yu Hansung's smile after Bam responds to him about the garbage at the top of the Tower hints heavily at his true feelings on the matter. He, himself, does not care about any of those riches and wants something that would change the Tower. Bam likely proved himself to be just the person to make those waves with his response.
- Inseries Nickname: Coffee Machine.
- Insufferable Genius: Called the "genius Wave Controller", and he is quite fond of his intelligence. Even as a Regular, his skill was way OP for his Floor Level — and, bleeding proud of it, thanks. If his data-memory is anything to go by, that is.
- Kick the Dog: Blackmailing Bam. Messing with Bam — past, present; same difference.
- Manipulative Bastard: Very good at making others play along with his schemes without them being aware of it.
- The Mole: He is a member of FUG pretending to be a part of Jahad's Empire.
- Mole in Charge: He serves as a Test Admin on the Floor of Tests for Jahad's Empire when in actuality, he's a member of FUG that's fighting against Jahad.

- Obstructive Bureaucrat: Has the authority and strength to do whatever he wants on the Floor of Test.
- Red Baron: Submerged Fish.
- Summon Bigger Fish: Pulls this on Ren and it is awesome. His epithet itself is the "Submerged Fish".
- Teeth-Clenched Teamwork: He and Bam are technically on the same side and fighting for the same cause, but due to him Bam doesn't exactly enjoy working with a copy of his younger self.
- Trademark Favorite Food: Instant anything, but particularly coffee. The quicker the better, so oodles of noodles are go! The story behind it, however, is much less goofy than you'd think.
- Villainous Rescue: Is one of the FUG Rankers that helps fend off Jahad's Royal Army to protect Bam and the other Regulars.
Augusgus

- Code Name: Gusgus. Not that hard to guess.
- Da Chief: A rather mild example, but an example nonetheless.
- Manipulative Bastard: Easily manipulates Love by acting like the latter screwed up trying to face off against Viole one-on-one in the Trustworthy Room test since it basically announced Viole's existence to the Tower. In actuality, Love did exactly what FUG wanted.
- The Mole: Secretly a member of FUG while working under the Jahad Empire.
- Mole in Charge: Works as the 20th Floor's Test Director for Jahad's Empire when in actuality, he's a mole for FUG that fights against Jahad.
- Red Eyes, Take Warning: Not shown in battle, but his status as a Ranker and his appearance automatically earn him this.
- Technicolor Eyes: Has a red sclera and golden irises.
- White Hair, Black Heart: A white-haired Ranker who's a part of FUG.

- Precision F-Strike: See above.
- Reasonable Authority Figure: Very, very much. Even after quitting, he's still on the trail of what happened and willing to help when he can.
- Shock and Awe: According to Word of God, he is capable of using Shinsu to generate electricity.

Quant Blitz
Voiced by: Hiroyuki Yoshino (Japanese), Xander Mobus (English)
Tower Position: Scout, Flame User
Rank: Normal Ranker
Occupation: 2nd Floor Test Admin (formerly); Wolhaiksong Intern (currently)
The 2nd Floor Instructor of the Scouts with a temper as fiery as his hair and all the maturity of an elementary school kid. Despite having such a persona, he is still a fierce and sharp-witted fighter. He served as the primary opponent to the Regulars during the Hide-and-seek test, and he's also related to Quaetro.
After being fired from his job on the 2nd Floor, he left with Lero-Ro to go to the 77th Floor and find Wolhaiksong. Alongside, Lero-Ro, Quant becomes a new intern for Wolhaiksong as the two of them go about infiltrating the Workshop Battle.

- Fiery Redhead: That one is in full effect.
- Hair-Trigger Temper: Yup. Just about anything will set him off.
- Honor Before Reason: A very idiosyncratic take on this, but, yes. Diss Scouting and he'll come at you.
- Inferiority Superiority Complex: Hachuling likes to exploit this for fun.
- Innocent Innuendo: Due to a mistaken translation, Quant became his widely accepted English name. However, SIU later showed his actual English name in a character profile later, meaning he's unfortunately named Qunt. Due to this being a somewhat offensive term (and fan inertia), the fan translators have continued to use Quant.
- I Was Just Passing Through: Towards Lero-Ro, even as friends.
- Jerk with a Heart of Gold: When he gives Bam hope to save Rachel during the Hide and Seek test.
- Large Ham: Lampshaded by Lero-Ro and Yu Hansung during the Hide and Seek test.

- Unwitting Pawn: In Yu Hansung's schemes.

During Bam's journey through the 2nd Floor in Season 1, Ren was tasked by the Jahad Family to sneak his way onto the Floor of Tests in order to assassinate Anaak due to her being a Fake Jahad Princess. In order to complete the task, Ren takes the guise of Test Admin Yuga, a sheeplike, horned costume that you wear like a bedsheet ghost costume and a smile that looks like mustard on rice. During his time on the Floor of Tests as Yuga, Ren served as the Instructor for the Regulars that were assigned the Wave Controller Position, which he ended up training Bam. Despite his best efforts, Ren's plan to kill Anaak was stopped by the arrival of the Ranker Princess, Yuri Jahad.

- Blood Knight: Gets very excited at the prospect of a good fight.

- Mentor Archetype: When he posed as Test Admin Yuga for the Floor of Tests, Ren served as the teacher for the Wave Controllers during Position Training.

- Blush Sticker: Permanently on his face, even during his Oh, Crap! moment.
- Curb-Stomp Battle: Effortlessly beaten by Urek Mazino. Also has tinges of Mugging the Monster: ineffectually and repeatedly prodding Urek Mazino, even by proxy? Dude should have guessed what was going to head his way.
- Eyes Always Shut: Classic example.
- Goggles Do Nothing: Except sit there.
