Joochun (주천, 酒川, Jucheon) is one of the Three Lords who rule the Tower in the place of Zahard while he sleeps. Of the three, Joochun is known to be a progressive Lord who strongly asserts the advancement to the next Floor. Because he loves alcohol, he was named Joochun for "alcoholic river" (Joo=alcohol; chun=river).
He was born between Ari Han and a mother who was native to the Tower, but his mother is said to have died as she gave birth to him. There is a rumour that he is a drinking buddy to Urek Mazino, but this is unconfirmed.
His real name is Ari Chun.
