|“||What fun would it be to become the king of the Tower? Tell Zahard to keep his boring seat. I will get out of the Tower. Outside the Tower, there exists a vast world, rolling skies stretch endlessly, and countless stars illuminate the darkness. A place that is a thousand times -- no, a billion times wider and freer than the tower. Once you imagine that such a world exists, don't you think all those things you want are all so trivial?||”|
Urek Mazino (우렉 마지노, "Urek Majino") is an Irregular, currently 4th in Rank. He was the strongest active Ranker before Zahard became active once again. He is also the most recent person to be part of the Top 5 High Rankers inside the Tower.
He is considered to be on the same level as Phantaminum by weaker Rankers, however, his true rank is almost impossible to determine in terms of the Top 4 ranks because the top 2 Rankers are inactive and thus, cannot be compared with Urek. He mentioned to Baam on the 43rd Floor that they would meet again later on the 77th Floor, then left the floor. His current location is unknown.
At some point, Urek tracked Phantaminum and followed him inside the Tower. It took Urek only 50 years to pass every test and climb all the way up to the top of the Tower. He is recorded as the fastest person to climb the Inner Tower through an orthodox method and it would probably be accurate to say he scaled the Tower faster than Zahard himself.
During his climb, Urek took Arie Hon's special test on the 100th Floor; the task was for Urek to endure his attacks for 10 minutes, but Urek fought evenly and passed Arie Hon's special test causing him to become the most famous Ranker in the Tower as a result. After becoming a Ranker, Urek used his reward from the test and took control of the 77th Floor; he then transferred the control again to Baek Ryun, who set up the stronghold of the Wolhaiksong there.
There was a time when Urek, who had a complaint about his rank being lower than Phantaminum's, broke into the Ranking Administration Office, captured Robert Aisand and threatened him to raise his rank. To Urek, who asked, "Have you ever seen me fight Phantaminum?" Aisand answered briefly and without hesitation "You will be the loser". Urek Mazino, shocked, could do nothing but go home bitterly. As a result of this incident, a number of jokes about Mazino emerged and nicknames like Urek Ma-Loser and Loser Mazino appeared. This climaxed into the production of comic strips featuring the incident which Baek Ryun said would "prove quite useful in the treatment of chronic depression". It appears that Urek has managed to get over this incident.
Urek's appearance on the Tower upset the High Ranker rankings which had been frozen for quite some time.
Appearance and Personality
Urek is a tall man, noted to be handsome. He has blonde hair, piercing red eyes and a well-defined musculature with a tattoo of his name and the Wing Tree symbol on his back. He generally wears a snapback backward on his head and has a 'rapper' look about him.
Urek is said to have a ruthless personality, leading him to be respected by all those who dare call themselves men and at the same time seems to be disliked by seemingly every woman he meets. He is also shown to be extremely confident to the point of arrogance, often ridiculing the efforts of those who were no match for him.
Despite his ruthlessness and boastful nature, he still wants to help others and friends in need, (e.g. Baek Ryun with his "relocation" and Ha Yuri Zahard for Zygaena's Flower matter). He will also help strangers if he thinks they are "worthy" to be helped (e.g. the young Hell Joe). He respects one's courage, determination, and nobility. (e.g. Viole who dared to challenge him despite being a regular or when Viole protected Miseng from his attack at the cost of him being severely injured).
He is also not entirely without mercy, as he was willing to spare Team Tangsooyook if they were willing to give up the Zygaena's Flower. Even with all his arrogance, Urek does not consider those beneath him as bugs like Gustang did, with it being the main reason why he despises the Po Bidau Family Head.
In the Hidden Floor, his enemy data which is a version of himself is much smaller like a child. He has a scar on his face due to the errors the real Urek Mazino created back when he was a regular in the Hidden Floor.
Urek's sobriquet is Ray Barracuda (레이 바라쿠다, "Ray Barracuda"). Ray refers to his combat style, in which he fires shinsu at the speed of light. Barracuda is the name of the most aggressive and ferocious White Steel Eel in the Tower. Although his formal sobriquet is Ray Barracuda, just Barracuda can also refer to Urek in the Tower.
As the second strongest currently active Ranker, just under Zahard himself as of recently, as an Irregular and as one of the founders of the Wolhaiksong, Urek Mazino is one of the most influential and feared people inside the Tower. Moreover, it is not an overstatement to say that his every single move affects the future of the Tower.
Powers and Abilities
As the holder of rank 4 in the entire tower, Urek holds a vast amount of power and skill, easily outmatching almost everyone in agility, strength, Shinsu Control, and many other fields of battle and is also extremely skilled and aggressive in almost every Position in the Tower, his main Position being Fisherman. After entering the Tower, he was able to pass all of the Floors to become a Ranker the fastest out of anyone in the Tower's history, taking only a tenth of the average time people usually scale the Tower in (50 years). Prior to the Zygaena's flower test on the 21st Floor, Urek killed several Rankers that were sent after him and soon after easily beat back Team Tangsooyook and nearly killed Baam with a single tremendous attack, although Baam managed to scratch him before going down and he was protecting Miseng. After the test, he completely foddered the three Rankers that came to stop him within seconds. He also claims that in order for him to not be embarrassed while talking about it, it has to be at least 1000 other Rankers against him. When shinsu is controlled by Urek, it takes on a yellow-white hue. Urek Mazino, while standing on his final Position, had once knocked down a Light Bearer who was also on their final Position; figuratively speaking, it's similar to a goalkeeper scoring a goal from across the entire field. Yu Han Sung said to Lero-Ro that the only known person to use shinsu without a contract from the Guardian and not from a Great Family is Urek.
Urek has been extremely powerful even back when he was just a Regular climbing the Tower. The "God" of guardians said Urek was definitely much stronger than him when the latter encountered him on the Hell Train and he is among the few, with the only other exception being Zahard and the 10 Family Heads, to have ever defeated him. Baam later stated that while the "god"'s tremendous power was similar to Urek, Urek's power felt much greater. Even more impressive was that he was also able to fight on the same level as Arie Hon, the strongest of the 10 Great Family Heads, and was the first person in the Tower's history to pass his special test, in which the rules were of "enduring" his attacks but Urek's exceptional power and skill allowed him to deny the rules and instead battle him equally; regardless of their even skills, Arie Hon would admit after the fight that Urek was "far better".
Immense Physical Strength: Urek has shown extraordinary levels of completely monstrous physical strength to the point that despite limiting himself to a max of 1% power output and using only his index finger, Urek still managed to effortlessly overwhelm the slayer Karaka, punishing Karaka's attack with a shockwave that cleaved Karaka's body and devastated the area, with Hoaqin noting that the attack would have killed him had he not been shielded. After injecting Joe with the drug that began to separate him from Red Tyrassa, Urek was able to forcibly rip him from Joe's body with a single punch and then easily completely render Tyrassa helpless with a grip to the neck and crush it bare-handed.
Immense Shinsu Resistance and Durability: Urek has demonstrated unseen levels of immense shinsu resistance. He can effortlessly resist almost any Lighthouses to the point that he openly brags on how useless lighthouses are against him and has claimed that even Opera can only stop him for more than 0.1 seconds. In a later fight, he came out completely unscathed from Karaka's shinsu attack. Urek also easily shrugged off Red Thyrassa's shinsu beams and also displayed immense physical durability, taking punches from Red Tyrassa with no injuries to himself.
Extraordinary Speed: People who have seen Urek Mazino in combat have evaluated his combat style as "aggressive, ferocious and fast, but very beautiful". Mazino has enough raw speed of movement in that he can travel roughly fifty meters from one stance to a mid-air kick in a literal instant. In his fight with Hell Joe, Urek was able to effortlessly jump from Baam's Shinsu Bubble to another to avoid Hell Joe's attacks and was able to quickly catch him off-guard and grab his arm as well as stab Hell Joe with the syringe to remove Red Thyrassa from him without him even noticing.
Shinsu Mastery: Urek is extremely proficient in the use of shinsu, as he has been seen to be capable of controlling shinsu with great ease, as if by pure bodily instincts, to tremendous effect, able to create large explosions and powerful Baangs as well as greatly enhance his punches with minimum effort and can unleash shinsu at the speed of light. an ability that is fired with enough power that even specialized equipment cannot block it, as shown when he fires a massive white shinsu beam that obliterates two Rankers before they could even get close. His shinsu's mastery and power is even so great that with only 10% of his power, Urek effortlessly outmatched Hell Joe powered by Red Thyrassa, able to easily send him flying a great distance and with a single beam fired from the simple flick of his fingers, completely dispersed an attack from him, utterly shocking Joe with his exceptional power over shinsu. With a single Baang, he easily destroyed Red Thyrassa when hitting its weak point.
- Shinsu Reading: Urek was able to detect the power of Red Thryssa inside Baam's body.
- Flight: like most Rankers in general, Urek can also fly, levitate and stand in mid-air as if he is standing on solid ground.
- Wonsul: Urek created a white round barrier to protect Ja Wangnan and Yeo Miseng from his attack when he intended to kill Karaka and White.
- Supreme King's Scorching Fist of Death (패왕열사권, Paewangyeolsagwon, probably 覇王熱死拳): A technique in which shinsu is gathered entirely into the fist and released in a giant explosion. Urek claims it is a "legendary" technique. Even while he massively held back the strength of the technique, it was powerful enough that Urek was able to easily severely injure someone of Viole's level of shinsu resistance in a single strike although it should be noted that Viole was shielding Yeo Miseng and was not fully focused but it would have made little difference. It can be inferred that its true destructive power and lethality, when used at full power, is many magnitudes greater.
Spatial Distortion: Urek is able to distort space in order to quickly travel across far distances. As Gustang noted, it is a very dangerous technique and can have serious consequences for every organism on a floor. 
His relationships are somewhat dull, partly because of his masculine manner. He has a magnanimous personality but is very unpopular among women. On the other hand, he has great support and respect from men due to his tremendous power and famous ruthlessness.
- Garam Zahard: Urek fell in love with Garam Zahard on the Floor of Death but Garam rejected him bluntly, telling him to screw off and even calling him shitface, and his repeated attempts caused her to ban him from the Floor of Death. The fact that Urek Mazino had a crush on the Zahard Princess but that Garam herself hates Urek Mazino became a famous rumor even though it was never confirmed. Despite Urek going out with other girls, he could never let go of his feelings for her.
- Ha Yuri Zahard: As Yuri was present at the planting of "Wolhaiksong", Urek has a friendly relationship with her and is more than willing to accept tasks from her. However, Yuri spoke of him and stated, "He's the best man to fight with, but the worst man to live with". Despite being much more powerful than Yuri, he ironically shows genuine fear at Yuri's temper, expressing nervousness when she angrily kicked and beat on him after learning he had a part in creating Hell Joe.
- 10 Family Heads: As among the very few in the Tower whose power is greater than the 10 Family Heads, they, even Po Bidau Gustang, acknowledge his power and consider him an equal, although they deem Wolhaiksong as just a deception. 'White Sword' Arie Hon praised him as a true warrior after he fought him to a stalemate during his test and even admitted Urek was far better while Khun Eduan picked Urek as "one of the people I wish to battle". It is unknown how he regards the rest of the Family Heads but what is known is that he has considerable distaste and is on bad terms with Po Bidau Gustang: Urek's first meeting with him to find a way to leave the Tower ended badly enough to give Urek a headache and he even said, “It'll be easier for me to dig my way out of the Tower with a spoon than to learn anything from that guy”. When they interacted in the Floor of Death, Urek was immediately suspicious and went as far as to use Spatial Distortion to teleport to Gustang and outright demanded Gustang to return the souls in his grasp. Urek also showed nothing but distaste for Gustang's arrogance that exceeded even Urek as the Po Bidau Family Head treated everyone else except him, the other Great Warriors, and Zahard as a bug. He is rather familiar with their skills, recognizing Shinwonryu when Baam used it as their shinsu control skill, but has indicated that his relationship with the other 10 Family Heads aren't much better than his with Gustang, as he spitefully referred to them as goddamn idiots and that he doesn't hang out with them because of that.
- Baek Ryun: Baek Ryun, known to be Urek's best friend, said that Urek is the number one comrade and man. As they are both cofounders of 'Wolhaiksong', Baek Ryun has a special relationship with Urek and the two's influence inside the Tower is comparable to one of the 10 Great Families.
- Hell Joe: When Urek was moping over Garam's complete rejection on the Floor of Death, he met Hell Joe, who wasn't afraid of him at all and in fact excited by Urek as he was from the outside. Urek in return was fascinated by Joe's huge dream of getting every inhabitant of the Floor out and believed he could get everyone out and gave him Red Thryssa to help him. When they meet again, Urek was visibly shocked and disappointed on what he became and uncharacteristically chose not to kill him to kill the monster for good but instead holds back to have Red Thyrassa take over so he can remove it.
- Twenty-Fifth Baam: Urek has taken an interest in the new Slayer candidate Jyu Viole Grace, partly because of Viole's status, partly because Urek is impressed with Viole's character and partly because Viole managed to scratch Urek in the cheek even while he was protecting Miseng. When they meet again, despite their previous clashes, neither of them seems to bear any ill will: Urek even admitted he was aware Viole had entered the Floor of Death and came there to help him as they shared the same goal to dethrone Hell Joe and they had no problems working together, Urek even complimenting Baam and expressing a desire for him to join Wolhaiksong. Urek also gave him advice on his Irregular status.
