Nah, fuck her up Sylphy! Show #2 where her place is in the hierarchy.
Her place is in Hell, after having been put in the dirt by Sylphy.
So, after all this are we (or the MC really) suppose to accept her in any shape or form? What a terrible way to introduce a supposed team mate. Though i'm sure "step on me mommy" freaks will love her for sure.
Bet the answer's a straightfacedly confident "Yes". See, there's already been quite a few people here talking about "correction" or how "hot" that thing is; the "correction" talk is because they see the promise of pedophile bait in Lucelia, while the talk of sexual attraction has an obvious cause.
Lucelia isn't just physically ugly (she has a goat's pupil and a horn coming out of the other), she's
flagrantly ugly of character, which neither the author nor the mangaka spare any expense in illustrating--and yet you still see people ignoring her actions to talk about how strange they feel at the sight of her. You will, I bet, later see some people adopt a similar mindset to what
@kingdedede said and think that the demon's interactions with Nekota absolve her of any and all guilt of everything she's done--the same way people think an abusive, 99%
tsuntsun girl is just "dishonest with herself", especially if she's flat or otherwise looks like pedobait.
No, that's just a girl who can't stand the guy she's interacting with--the same way Lucelia is the degenerate's choice.
EDIT: I'm expecting it too: Kaito will probably squeal about wanting the two to "get along", or even look at their fighting and call it such with a smile. He already got on all fours before that demon when he saw her burning Sylphy.
