After the party speaks to Lularita, a level 37 Hardy Aprica and two level 37 Corpse Sacrifoles appear at the end of the path behind her, near the entrance to Bestial Utopia. They may be the "big scary critters" mentioned by Lularita. It is not necessary to fight them. If killed they will respawn one minute later. They disappear after the Reverend's Journal is obtained.
