I have always wondered about that as well and simply waited for that to answer. I think it might link to why Rachel chooses that day to enter the Tower. Since we have no idea how long both Rachel and Baam arrived at the Base Floor (Baam appeared a bit later than Rachel), I imagine "something" happened (which enables whoever that someone to tell Princess Yuri) and it leads to Rachel, maybe taking it as a sign, to climb the Tower. In Chapter 1, it can be seen that either Rachel might not tell Baam where she was going or she simply saw a sudden sign ("spider thread") and decided to "grab it". Currently, it is just a theory but knowing SIU, he probably has a plot for it.
