I see athy in her too much. It's almost creepy. It's like they twins.
she's Athy's mom, you see
for the plot, well partially it's because athy has too much mana that diana's body can't keep up with her.
I know but It's still kinda creepy. Specially in that one latest Panel where claude and diana were on a walk. Like when she grabbed his hand i was like the heck? Athy? Gurl why u here, where ur mom?
Now, Im questioning creator-san why she killed Diana. Damn. She's so gorgeous. I will use black magic as well. Not to forget her but to revive her.
