KiRA didn't know why there were exactly three certain elements on each floor that stood out from the entire theme of the floor or were simply not supposed to be there.
He knew there were a lot of things that were different in this tower, but since he had not found anything out of place on the first floor aside from the things that he knew about, he didn't yet rule out the possibility of there being more different pieces.
The first floor's traveling system, the mausoleum of a higher floor being that housed beings that weren't supposed to be down here, and the demoness that was trapped here out of her will.
The presence of a different demon did not change the nature of the floor, instead, it simply made it more complex while keeping the theme of the hidden piece consistent.
KiRA found the Leaf Fay so easily thanks to their encounter with Lia and her party. The fact that they had not encountered the 'butterfly' anywhere around this floor was proof that it might not be here.
