At the top of the Ruling Class are Zahard and the 10 Great Warriors, who conquered the Tower and gained control of the first 134 Floors from the Guardians. Since they are not native to the Tower, Zahard and the 10 Great Warriors are are technically Irregulars, but are rarely referred to as such. Zahard went on to establish the Zahard Family, who are considered royalty, and the 10 Great Warriors founded the 10 Great Families, who are akin to aristocracy in the Tower; all of their descendants benefit from the contracts they've secured with the Floor Guardians. All of them are High Rankers, and though generally inactive, they are central to the main story.
Tropes related to the entire Zahard Faction
- The Ageless: Climbing The Tower gave them eternal youth, with the exception of Hendo.
- Complete Immortality: With the exception of Hendo Lok Bloodmadder, who struck a special deal, all of them have been granted immortality by the 100th Floor Guardian.
- The Dreaded: Considering they are the strongest inhabitants of the Tower, they are widely feared.
- Drunk with Power: Most of them didn't start out as the jerks they are now. The data version of Koon Eduan notes that the stronger they grew, the less and less they cared about other people. Po dismisses regular people as irrelevant bugs. Zahard took it to the extreme, betraying and tyrannizing everyone to gratify his own ego. The only exception was V, who grew closer to other people instead.
- The Ghost: The majority of the Family Heads are residing in their residences and are not active in the public; SIU has noted it is a very, very rare occurrence for one of them to speak directly to their family members.
- Large and in Charge: Zahard and his Ten Warriors are all said to be very large and bulky; this is best seen when the real Zahard appears in the Hidden Floor, towering over his younger self and Baam.
- Might Makes Right: Although the Tower has never been a happy, pain-free place of easy choices and quick rewards, there are more than a few elephant-sized hints that the really sucky dog-eat-dog, power-based pyramid scam of a society we come to know through Baam and company is entirely down to them and their choices, rather than being intrinsic to the structure. Considering they made the system...
- Nigh Invulnerable: Per their contracts with the Floor Guardians, none of them can be harmed by inhabitants of the Tower.note Irregulars, not being natives of the Tower, are exempt from the contract and are able to kill Zahard.
- Really 700 Years Old: Probably among the oldest in the Tower.
- Retired Badass: None of them are active in the public. They don't even appear to leave their homes anymore as they have no reason to.
- The Runaway: One of the stories about how they got into the Tower paints them as defeated remnants of a war desperately fleeing the consequences of their defeat. Who somehow worked out how to disappear by going inside a place none could easily follow.
Zahard is the famed "King of the Tower" and the most famous and greatest being within, akin to a god to the Tower's inhabitants. Long ago, he entered the Tower with his Ten Great Warriors and built the Zahard Empire, gaining control of the 134 Floors from the Guardians. He is the first to form a contract with a Guardian, and became King through these contracts. This conquest is known as "The Great Journey". He is lord of the Zahard family, whose Princesses are powerful females endowed with his blood and are among "the most powerful kind" in the Tower. It must be noted, however, that none of them are related to him by blood, as Zahard has no spouse or heirnote .
Zahard is currently resting, leaving the affairs of ruling to the Three Lords and his daughters, although it is believed that when Zahard is on the move again, the 135th Floor with be conquered.
His death is the longed for wish of the famed criminal syndicate FUG, however none of the Tower can harm him.
His younger self was the ruler of the Hidden Floor, entrusted with a bracelet that was the key to defeating him. At the climax of the arc, before the floor is deleted, Zahard attempts to retrieve it, but it is stolen by Gustang's invisible manta ray given to Rachel. Perhaps as a consequence of seeing evidence Gustang is plotting against him, Zahard issues an order to kill the entire Po Bidau family.
- Ambition Is Evil: His destiny was to become a king that stands above all others, which translated in the modern day to being a cruel and ruthless tyrant.
- Archnemesis Dad:
- He is implied to have in some way fathered Ja Wangnan and Karaka, both of whom want him dead.
- A few of his adopted daughters among the Princesses of Zahard are not fond of him either.
- Authority Equals Asskicking: Oh hell yes. Even prior to entering the Tower, he was challenged by Arie Hon, the strongest of his companions ten times. He won every single time, which is why Hon follows him. He was firmly #1 in the Rankings, and it was only after an Irregular killed a Floor Guardian and his own inactivity that has put him in third. Even still, a mere fragment of his power is still capable of freezing the data versions of his younger self, the ruler of the Hidden Floor, and Koon Eduan, as well as rendering Baam completely immobile.
- Blood Knight: Eduan mentions that he enjoys opponents who face him fearlessly. While he's unenthusiastic at first, once he gets motivated he starts to become uncontrollably powerful. Likewise, he calls his fight with Data Maschenny the most fun he's had in ages, and is holding Baam to a higher standard precisely because she fought so well. When Baam fights Data!Zahard to a standstill, he gives Baam his bracelet so that he'll someday give the real one a decent challenge.
- Blood Magic: The process to make a Princess of Zahard involves his blood, and the rings Karaka and Wangnan has are both suggested by SIU to be made of clotted blood.
- Big Bad: He is the main reason the Tower is a Crapsack World, and many people believe God chose Baam to kill him.
- Bold Explorer: Before he became obsessed with being a tyrannical king, he enjoyed exploring and identified as an adventurer.
- Deep Sleep: Said to be "hibernating"; but how long he has been sleeping is unsure, as it is rumored he interfered in the Enne Zahard incident.
- Chekhov's Skill: A Loophole Abuse. He essentially can use the Flare Wave Explosion (a melee killing technique) at long range by vibrating the shinsoo in the air instead of in the victim's body.
- Deer in the Headlights: Not himself, but he appears to be able to cause this to any Princess of Zahard, causing Maschenny and Androssi to freeze and become unresponsive when they see him.
- Evil All Along: It is becoming increasingly apparent as the story progresses that FUG might not be entirely in the wrong in their desire to kill Zahard. Zahard, the King of the Tower and created the system by which Regulars can climb the Tower to obtain their greatest desire, does not appear be the Good Guy as we were originally led to believe and actually is the cause of a lot of the death and conflict in the upper echelons of the Rankers.
- Fallen Hero: Maybe. The data version of Yu Han Sung mentions that the Zahard on the outside has turned his back on loyalty and justice, and Eduan, one of his companions, thinks the data Zahard is fake because of how out of character he is acting. The reason Zahard wanted power was to make the Tower a place where everyone can be happy. On his "becoming a king", he also states that it is his destiny, whether he likes it or not. All of this implies that originally, Zahard was someone who genuinely could be called a hero, a worthy chosen of the Tower, but something happened to him that changed his personality.
- Fangs Are Evil: One of his characteristics.
- Fighting a Shadow: Baam's first meeting with the real him is with a small fragment of his power, and he promptly gets nearly killed as Zahard immediately attempts to break his neck. He very nearly succeeded too, if the Thorn had not tried to forcibly take Baam away.
- Future Me Scares Me: Data Zahard is both awestruck by his current self's prestige and power, deeply concerned about the anxiety he can feel from him, and confused on why his true self isn't quite going along with the new challenge Baam represents like his old self would. As the data world is destroyed, he privately asks why the other family leaders and himself changed to become the way they are now.
- Game Face: He asks Baam if he sees a human or a monster, briefly shifting into something that causes Baam to automatically attack him while screaming. He has not shown this form to anyone else so far.
- God-Emperor: He is a Physical God, holds absolute power over the Tower, and is often a subject of worship by the Tower's government.
- Greater-Scope Villain: A prophecy suggests Baam is meant to slay him, but Zahard has yet to get personally get involved in the plot. Nevertheless, most of the misery and conflict in the tower can be attributed to his actions. He finally starts to become active after the events of the Hidden Floor.
- Graceful Loser: After his data self loses an arm to Baam and both briefly succeed in a Double Knockout, he admits his loss and hands over what Baam has been looking for with little fuss.
- Hidden Depths: While initially coming off as cool-headed, coldly authoritative and distant, even uncaring to his former companions, Zahard in his youth was an "adventure freak" as well as a Blood Knight. There are also hints that he does not like his fate to be king of the Tower, but accepted it anyway.
- Interspecies Adoption: Zahard's Princesses aren't related to him; they're all adoptive daughters. So far we know of multiple humans, a horned humanoid and a lizard-girl, though we have no context for what species Zahard is.
- The Magnificent: King of the Tower, for obvious reasons.
- Named Weapons: Wields Lecalicus (most likely intended to be Regalecus), the "Needle of War" that he only draws for worthy opponents. It has three stages; Lecalicus that summons a Shinheuh when he swings it that takes the form of a Sinister Scimitar, and Coelacanth, a thin, ornate Needle that resembles a Royal Rapier that can emit shockwaves when he thrusts it, negating the weakness of Needles in that they can only be thrust. The third form is called Leviathan, however the capacities are still unknown (although it was powerful enough to counter one of Baam's strongest moves and knock him out.
- Physical God: The real Zahard is a nearly perfect being that flows with divine power, is near immortal, and is the subject of worship throughout the Tower. He is even starting to approach the point where he can control fate, much like God itself.
- Red Eyes, Take Warning / Supernatural Gold Eyes: Beneath his mask, his eyes are an ominous red mixed with gold. Initially it seemed his eyes were red, however SIU changed it slightly to be gold, turning redder when he becomes "serious".
- Shrouded in Myth: Sleeping for ages does mean most people know nothing about you beyond tales.
- Screw Destiny: Once upon a time, he believed that if he was destined to do something, he had to go through with it. But now, as he becomes more and more like God, while he isn't completely opposed to his fate to fight Baam, he is also taking measures to have Baam killed before it can happen.
- Slasher Smile: When Zahard gets excited about an opponent, he shows his teeth.
- Spell My Name with an "S": Zahard or Jahad? The official LINE translation goes with the latter, but the fanbase is more attached to the former.
- Third Eye: His crest is the Red Three Eyes, which he also wears as a mask. However, Zahard himself does not have a third eye.
- Utopia Justifies the Means: According to the "God" of guardians, Zahard originally became king in order to make the Tower a place where everyone can be happy. Needless to say, this didn't work out, which is why the guardian warns Baam when the latter asks to become a god.
- Used to Be a Sweet Kid: Well, "sweet" is perhaps overstating things, but young Zahard shows nothing even remotely close to the tyranny and evil he displays in the current day and age. He was more focused on adventure and fighting than anything else. SIU noted that if it weren't for their destiny, Zahard in his youth and Baam would have gotten along extremely well, comparing the relationship to Wangnan and his changing of Baam when he was still acting as Viole.
- Villain Respect:
- The data version of him shows it towards Koon Maschenny Zahard's fighting spirit.
- The data version of him also shows it to Baam when Baam fights him to a stalemate. Their fight comes to remind him of how much he enjoyed adventuring, and he gives Baam a key to help him defeat the real Zahard in the hope that Baam can give the real him the thrill of adventure as well.
- Virtue Is Weakness: He sees being a King as being an existence that stands above and separate from others, and sees being a monster as the requirement to do so. He erased both his enemies and his closest friends, and claims to have forgotten Arlen Grace for this reason.
- Winds of Destiny, Change: He informs his Data self that he now sees cause and effect from the same height as God, and is starting to become powerful enough to control fate.
- Yandere: He had a crush on Arlen Grace, but she chose a man called V instead and opposed Zahard's rule. Baam merely mentioning her name to his data self causes him to clam up briefly, before demanding to know who Baam is and threatening to kill him. Zahard had her child killed in front of her after she and V betrayed him and founded FUG. In the current era, Zahard seems to have calmed down tremendously, remarking that "Fate is really toying with us" when he meets Baam, but remarks that he didn't think he would get another chance of killing him. That said, he seems to attempt to comfort Baam, calmly asking Baam to rest in peace as he will send all his friends and everyone he ever met to him once he's killed them personally. He still appears to carry a torch for Arlene, however, calling her "the woman I loved more than anyone".
- You Can't Fight Fate: Something he once believed in, whether he wanted to obey his Fate or not. However, he is starting to become powerful enough to control it himself.
One of the warriors who accompanied Zahard during his conquest of the Tower, and founder of the noble Arie Family, the strongest family in the Tower. Not counting Zahard and the top Irregulars, he is the strongest High Ranker in the Tower and seen as the strongest of Zahard's Ten Great Warriors. His sobriquet White Sword refers to the White Oar, his sword that doesn't get hindered by dense Shinsoo.
Hon is known to give special tests to Regulars who reach his floor, the 100th; only two known people have succeeded in passing one. Urek Mazino, whose task was to endure his attacks for 10 minutes although Urek went above and beyond by fighting Hon evenly, and his daughter, Arie Hagipherione Zahard who wields the Red October. Since fighting Urek, he has not fought a battle.
Perhaps ironically, he indirectly assisted in the founding of Wolhaiksong. Urek's reward for matching him in battle was the control of one of the Floors he owned, and Urek later used the floor as the group's headquarters.
- Always Someone Better: Urek Mazino. Despite being the strongest High Ranker, Urek, then a Regular, was capable of fighting evenly with him for ten minutes and was the first person to ever pass his test. However, Hon does not appear to mind being surpassed, having gracefully admitted after the fight that Urek is much better than him.
- Archnemesis Dad: Deliberately became this to Hoaqin and his siblings. Hon, for his part, did not even know Hoaqin's name during their meeting and delivered a speech that served as his Start of Darkness.
- The Corrupter: He is the one who told Hoaqin to become the monster he is today, encouraging him to give in to his murderous urges "until everything seems pointless one day".
- The Magnificent: White Sword/Oar, after his weapon.
- Master Swordsman: He's the leader of a family renowned for their swordsmanship; Hoaqin remarks that Hon was the most brilliant sword he had ever seen, and Gustang is of the opinion that he cannot be matched or reached by anyone.
- Named Weapons: Owns the White Oar, the only sword forged by Macseth and the only weapon in the Tower with the rank of S+. Warriors in the Tower say that the sword is "like an oarfish", a legendary White Steel Eel.
- Retired Badass: While to a degree this applies to all the Family Heads who are not active in the public, Hon has not fought anyone after he fought Urek.
Head of the Khun Family, one of the 10 Great Families, and also the father of numerous children from the Koon Family, such as Koon Aguero Agnis. His family is known to be one of the greatest in the Tower, acknowledged to be one of the few equals to the great Arie family. Before Enryu appeared, he was the strongest Spear Bearer in the Tower.
Eduan also has a younger data version of himself within the Hidden Floor that is working against the data of Zahard.
- Always Someone Better: Despite being friendly with Arie Hon, he resents him a little for being ranked higher. He also wants to fight Urek Mazino for pushing him out of the top five Rankers.
- An Ice Person: Curiously, he is an ice user despite being most famed for his electricity. Eduan notes that ice is an extremely rare ability, and possibly makes one suited for the role of Spear Bearer.
- Archnemesis Dad: To Aguero Agnis, who seeks to take his position as family head.
- Battle Aura: Gains one made of electricity when ready for a fight.
- Blood Knight: Known for taking delight in fighting.
- The Casanova: He's famous for his lewdness and possesses the most wives of any of the 10 Family Heads.
- Everyone Has Standards: His data version is disappointed in Zahard for becoming an arrogant king, to the point of calling him a fake.
- Glowing Eyes: Unlike the rest of his family, his eyes seem to glow and emits blue electricity.
- Jerkass: See Let's You and Him Fight below. This may apply only to his current self, however; Aguero Agnis notes that if his data version could see his current self, he'd want to run away. It possibly runs in the family, as SIU has noted that the Koon family trait is that they are "douchebags".
- Let's You and Him Fight: He makes his "children" fight each other in "inhumane and bloody" fights to stay in the family, and is apparently uninterested in the results. He has also offered anyone who challenges him and wins "everything from the family".
- Impossibly Cool Weapon: Mago. It is a compression-spear that, when expanded, is said to be able to "pierce half the Tower".
- The Magnificent: Marlin, after his spear and Blue Thunderclap for his attribute of electricity (he was originally considered for Electric Eel as a sobriquet, but Eduan took offense to that). Boro also calls him "the God of Spears".
- Power Tattoo: Has one on his right arm. It glows when he uses shinsu.
- Shock and Awe: Has the ability to use turn shinsu into electricity.
- You Gotta Have Blue Hair: Much like his children, Eduan has silvery-blue hair.
Head of the Ha Family and the first person in the tower to hold the Scout position.
Tu Perie Tperie
Head of the Tu Perie Family and the first Light Bearer in the Tower's history. After Zahard and the 10 Family Heads stopped climbing the Tower, Tperie worked closely with the Workshop to construct numerous items. The most famous of their creations are the three Opera Lighthouses, the greatest Lighthouses in the Tower.
Head of the Eurasia Family and the birth mother of Eurasia Enne Zahard.
Po Bidau Gustang
Head of the Po Bidau Family and the first living being to systematically record Shinsoo. Po Bidau Gustang is the Towers most famous Wave Controller and writer. Excluding the eccentrics within The Workshop, he probably knows the most about The Tower. He was also the lover of Eurasia Blossom for a brief period, and is the father of the famous Princess Eurasia Enne Zahard.
Gustang is the founder of the Research Association, and all males of the family are required to become a member. If they do not succeed, they are kicked out of the family. However, because it is a very powerful and exclusive group, his family enjoys great reputation and power, on par with the Koon family.
He is rumored to know a way out of the Tower.
While he was loyal to Zahard for some time, the modern era has seen him quietly working against him, eventually resulting in Zahard declaring war on his family.
- Anonymous Benefactor: Aids Viole and the gang during the Workshop Battle for unknown reasons, allowing them to keep Viole and the Thorn as well as officially winning the Workshop Battle much to the chagrin of the organizers, and not even the Rankers helping them knew he was there.
- The Casanova: After splitting with Blossom, it is noted that he became something of a ladies man.
- The Chessmaster: His exact motivations are unknown, but some suspect he is betraying the 10 families. He made the floor of death the way it is now and has been subtly manipulating events, seemingly to aid Viole.
- Condescending Compassion: Displays it towards Hoaqin over the fact that he got cursed as a side effect of stealing souls, calling him a poor bug.
- Defector from Decadence: He originally sided with the rest of the 10 Great Families, but at some point, for reasons implied to involve what Zahard did to his favorite daughter, started working against Zahard.
- Driven by Envy: Was very interested in Eurasia Blossom because she was able to control Shinsoo naturally, and was extremely envious of her talent.Gustang: Blossom is one of the greatest Wave Controllers, but she cannot teach you anything. This is because she herself does not know how she controls Shinsoo.
- Badass in a Nice Suit: One of the best-dressed character in the series.
- Insufferable Genius: He is a close friend of the Gong Bang, exchanges stories with Macseth, pioneered the research of shinsoo, and founded of the Research Association. He also looks down on everyone who isn't a Ranker and casts out any member of his family who does not succeed in becoming a member of the Research Association. However, he has made an exception for Baam, saying that he may be capable of standing with the 10 Family Heads and Urek. See Condescending Compassion.
- The Magnificent: Known as the "Aloof Wave", perhaps owing to his quiet, reserved appearance. If this refers to his personality, he can be somewhat meddlesome when he wants to.
- Man in White: And natty he is, too.
- Man of Wealth and Taste: The Workshop organizer, Madoraco, even comments it's hard not to notice who he is based on the expensive cigarettes he smokes.
- Megane: Wears them to better read the flow of Shinsoo.
- Pitiful Worms: Considers most people to be nothing but bugs.
- The Professor: Is in charge of researching everything there is to know about the Tower.
- Smug Super: He is completely dismissive of lesser beings, referring to them as bugs and considering them utterly irrelevant to the scheme of things.
- White Mage: Refers to himself as an expert of science and medicine, and functioned as a supportive Wave Controller contrasting his one time lover Blossom, an offensive Wave Controller.
Hendo Lok Bloodmadder
The head of the Hendo Lok Family and the first person to hold the special position of Defender in the Tower. As a reward for passing its test, the Guardian of the 100th Floor offered Zahard and the 10 Great Warriors the gift of immortality. However, Hendo Lok Bloodmadder was the only one excluded from this gift. The reasons behind this exclusion are still a mystery.
The leader of the Yeon Family. Hana is known to be the most beautiful among the 10 Family heads. Despite being the Family leader, none of the children born to the Yeon family have her blood. They are instead born to Ilarde, an old fellow family member of Hana.
