Well I don't think her demon might be as powerful as Shikama, we're talking about the first progenitor being "God" himself.

But remember, even if there's a huge treat, Shikama will take everything as a laughing matter. For now, we know there's almost nothing that would bother Shikama. Shikama never takes anything serious except for when Shinoa attacked him in chapter 74.

Anyways, I will make an evaluation to Mitsuba's demon and also, in relation with the curse, I believe that Aoi isn't possessed but perhaps her role as a high ranking soldier makes her act cold towards Mitsuba.

And mostly, her traditions, we know that Aoi was cold and emotionless before the Catastrophe and this can only resume to training just like the Hiragi train their kids...yep those families are damn scary.

Perhaps we might see Mitsuba in action in the next chapter or perhaps in chapter 79; I humbly believe that something will awake her demon due to the current situation. Mitsuba really is a kind girl even if she has her tsundere side.

Maybe Kureto might know something because of the close relationship Aoi has with Kureto. I mean, Kureto has known Aoi for such a long time and in chapter 17 or 18 when Shinoa spoke with Mitsuba about how Shinoa's father never bothered to meet her, she mentioned Kureto, and Mitsuba obviously reacted towards this, meaning that Mitsuba knows somehow Kureto's demeanor towards low rank solders
