Urek Mazino/History

History
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.

At some point, he fought the High Ranker Quadrado and took the Ignition Weapon Kranos from him.

Flower of Zygaena
Urek Mazino ventured inside Zygaena with the goal of finding Zygaena's Child for Yuri, a request from Repellista Zahard. While doing so he killed several Rankers who were also after the flower. While inside Zygaena, Urek took a nap because he felt that it wasn't time to leave yet. He woke up when he sensed Team Tangsooyook coming inside, meeting Kang Horyang and Prince later on. He was about to kill them but upon realizing that they were just Regulars, he decided to let them walk out alive if they gave up on the test. Viole came in and refused to give up and challenged Urek. Since he found this amusing, Urek accepted and decided to play a game with Viole, stating that Viole had to get the flower before Urek caught and killed him. He gave Team Tangsooyook time to gather and attack him. He easily swatted away their attempts and plunged in after Viole. Just as the two of them were about to exchange blows, Miseng jumped in between them while she was attempting to grab the flower on Zygaena's child. Viole protected her, resulting in him becoming severely injured.

Urek is impressed at this and lets them have the extra flower that just grew and decided instead to take Zygaena child. As he left, Team Tangsooyook was shocked to learn that he was Urek Mazino (after seeing the tattoo on his back). Urek exited Zygaena to find three Rankers waiting for him. He easily killed two of them and disabled Noma. Noma demanded to know who he is and Urek replied, "Isn't it on my back? 'Mazino'". He left the testing area and met up with one of his followers, Yuje, telling him to tell Yuri that he got what she was looking for. He handed him the baby and discovered that Viole had managed to scratch him. He then told Yuje to have the new Slayer candidate watched. Because of Mazino decision, he was responsible for dispatching Hachuling (who hired Lero-Ro and Quant Blitz to help him) to tell Baam that he wanted to meet him.

The Hell Train: The Floor of Death
Urek appeared with Yuje near the Black Mountain station after Yuje saved Yeon Yihwa and Hong Danhwa from the aftermath of Ha Yuri Zahard's Rose Shower attack. When Danhwa awoke, he asked if they had seen a small crocodile anywhere but Urek replied that Yuje had only seen and saved the two of them. Then, after hearing that Baam's team had gone to the 43rd Floor, Urek suggested they better go there too.

After arriving at the 43rd Floor, Yuje gave Urek a special anklet that masked his power but would break if he used more than 5%. With Urek nonchalantly brushing it off, Yuje added that the boss said not to break it or Garam would dump him. Once inside the 43rd Floor, Urek tracked the scent of a girl's perfume until he encountered Karaka assaulting Ha Yura. After cordially greeting Wangnan as he recognized him as Baam's friend, he exerted his power to challenge them, believing merely 5% of his power would be enough against them. After being completely uninjured by Karaka's attack, Urek found Karaka to be too weak for even just 5% of his power and used only his finger and with 1% of his power to easily defeat Karaka, punishing his attack so hard that the shockwave devastated the surrounding arena while he protected Ha Yura and the others with a bubble of Shinsu. After seeing Karaka easily regenerate despite being torn in half, Urek recognized his self-regeneration as a spell but before he could prepare to properly kill Karaka, Karaka decided to self-explode himself, knowing that he couldn't even hope to beat one of Urek's fingers, and Urek is forced to protect Ha Yura, Miseng and Wangnan from the explosion and give up on killing him. He then took Wangnan and Yura towards Hell Joe, revealing to the two that he met Joe in a previous visit to the floor and gave him the Red Thryssa, never imagining that he would become a tyrant.

On the way to Hell Joe, he encounters Garam in the tunnels and hides, thinking Garam would never love him if she found out he gave Joe the Thryssa. He wanted to defeat Joe without her knowing, being banned by her from the floor of death after failing too many times to win her heart. Hockney persuades her to (unknowingly) forgive him, however, and Urek offers his help officially, going with Yuri and Baam to confront Joe.

Urek asks Joe why he became the dictator of South City when he wanted to use his power to free people from the floor, and Joe told him about the complacency of the citizens, the corruption of the Grand regime, and his eventual coup before attacking. Urek and Baam retreated, and Urek takes off his anklet to release his full power. Yuri attacks him and accuses him of being a prisoner, but Urek explains that he has a syringe with a liquid from The Workshop to separate the Thryssa from Joe.

Urek again confronts Joe and mourns for Joe's past, telling him he and his dreams have become smaller, as he easily neutralizes his attacks with just 10% of his power and even mocks on his beliefs of being the strongest, stating that there are still a lot of people from the Tower who could use shinsu to the level Urek was using to easily overpower him and how easy Joe would be slaughtered if he went into the tower. As Baam helps him get close by controlling the shinsu bubbles so that he can use them as platforms to jump across, he swiftly closes the distance while dodging Joe's attacks and grips his hand as he tells Joe how scared and weak he's become and provokes the Red Thryssa to fully take over Joe. The Thryssa thanks him for allowing him to revive, then attacks with a wallop of punches and more laser beams. Urek is knocked back, but unhurt, and he succeeded in injecting Joe with the syringe. He then forcibly removes the Thryssa from Joe's body and crushes its neck while telling Joe he doesn't need such a corrupting power. He then enlists Baam's help to stop the Thryssa's self-destructing shinsu explosion, having him control the shinsu to create an opening for him to send a baang into the weak spot, recognizing the shinsu control used by Baam as the same skill used by the 10 Family Heads, and once he succeeded in creating a crack, Urek used a single baang to destroy it once and for all. He finally thanks Baam, and asks if he'd be interested in joining Wolhaiksong.

They regroup with Baam's companions where he introduces himself, but the other regulars accuse him of being a creep. Yuri asks him how he knows about Garam, but he runs away to check on Joe. He tries to converse with him, but Joe accuses him of not being there when he needed him and then stealing his power. Urek encourages him and apologizes for corrupting him, saying he can be himself again and wants Joe to continue his original goal of breaking out of the floor. Joe retorts that Urek could never understand him and wants Urek to leave, but suddenly begins to disappear as White sucks up the souls in the spirit room. Yuri finds Urek and mentions the spirit room might have something to do with it, and an enraged Urek immediately departs to find Karaka and White and make them pay.

Urek, Yuri, and Baam's team find De Jah dead at the entrance, and Hwa Ryun offers to show Urek the path to the culprits, but the two, unfortunately, took a different path, and he suddenly feels a tremendous power that he identifies as Po Bidau Gustang, who has already thwarted White's efforts and removed the souls, and having never been friendly acquainted with him, immediately uses Space Distortion to reach him. Urek demands the souls and his friend back, but Gustang lectures him that he is too powerful to have friends, and has no equals besides the other Family Heads before finally returning the souls and reviving the citizens.

Urek returns to Joe one last time to tell him he and Gustang could find a way for Joe to leave, but Joe declines, citing his weakness. Urek fails to encourage him, hurt that he could not help him, and finally retreats. Gustang soon finds him moping, telling him not to be surprised and that Joe was just a bug beneath him, causing Urek to reiterate his distaste of him and the other Family Heads. He also will not go to Garam as he has no desire to kill Zahard which is what Garam wanted from him. He asks him if he should spare Joe when he wipes the floor's memory of recent events, but Urek declines, wanting Joe to regain his instincts to escape the floor.

Urek finds Baam's team again and warps them back onto the train, where he and Yuje tell Baam they met Ehwa and Danhwa, but not Rak. He questions if Baam is an irregular, and once Baam confirms his irregular status, tells Baam not to be entrapped by the tower's systems and others' burdens, and instead to be true to himself. He says his final goodbyes, then leaves with Yuje, believing he'll meet Baam again in a higher place. But as he leaves, he can't help but feel like he's forgetting something. This refers to the precious item Stealth Anklet, which he threw recklessly.
