マトカ

An elf sister full of motherhood.

Among the elves, she treats other races with a kind smile, which is rare. 
However, in reality, she believes in elven supremacy more than anything else, and believes that by serving the elves, other inferior species will become superior even among inferior species.

With kindness and love, he preaches that the elves are supreme, and that's why he's seen as the most dangerous of all.
