Urek Mazino (우렉 마지노, "Urek Majino") is an Irregular and Vice Captain of the Wolhaiksong, 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.
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.
He is the self proclaimed "Champion of the Tower" and believes himself to be the strongest.
