The Godawful Thing Climbing up the Tower is introduced in the Ch 4 Interstitial where Estaven is starts by asking Sabitha to show him "Any more hot babes down there?" and "But what about people who got trapped there? Are any of them strong or hot?" It also uses the same portrait as one of the spirits of the Zirantian Incubus King's harem members. So it's probably safe to assume that that it's female.
