The switch from Arnest to Earnest has me really fucked up because, all I can think of when reading that is this guy
and the dissonance is killing me.
That aside, like Asmodeus, Cu is ABSOLUTELY aware of Earnest's affections, (was it the boot to the face in the bath?) but disapproves. Partly because of her being a rival for papa's affection if they were to become an item, I'm sure, but also because she can't acknowledge her yet. After the group defeats her, will she be more likely to call her mama or rival (not saying she has romantic feels for Papa)?
@Drifter if it can restore limbs and the armor that was on them as if it never left, it's probably just shy of straight respawning a person. The fact that it restores equipment puts it in a different class above healing. As long as they don't die instantly she can probably save them. At least until her mana/power runs out.
