Are we going to meet Grace's grandfather? We've seen Grace's family tree in chapter 17 and all we've learned about her grandparents is that they live somewhere else, at least now we have a name.
I do like how the mob ladies had their character growth, being inspired by Grace and Anna to better themselves.
It seems that despite being a Japanese manga, we're using chinese philosophy for the magical elements, with wood and gold/metal being present. If the author used japanese traditions, we'd have the classical 4 elements of fire, water, air and earth as well as the fifth element of void/aether, which also was present in western philosophies and could connect the western and eastern countries of this title together.
Thank you for the translation.
