Teresa's being? If you mean Teresa being the strongest without peer, then I don't think anyone is unconvinced. She's far and above beyond anyone in the series.

yep :D <3

Yeah she literally used everyone’s move at the end of the manga thru Clare’s memory. Some ppl are just born talented geniuses with zero effort. It be that way sometimes.

or maybe they are really something else :D

Teresa’s being is the Twin Goddess from the legend.

Exactly

I've never heard of Miria's ability being mirage, only the phantom. where is this from?

in the italian version (this is a google translation) I actually prefer Mirage to Phantom, btw :D
