Milliendra smiled when she realized how many people cared about her… while so many people were risking their lives to help her and protect the world as well. Only a single person can't decide if the world is worthless or not. If all those people wanted to fight the demon god to protect the world, then it was because they felt like the world was something worth protecting.
"Milliendra, you were chosen by a foolish man who calls himself demon god to become the vessel of his powers and to revive him," the gentle female voice said. "You were unable to touch people because of his power to drain mana from others… It was because of that that your mother died. Zaos Sielders wanted to protect you from that fact, just like your mother. That was why she asked him to kill her… even though that hurt her heart and her dear friend's heart more than anything. Can you deny that, self-proclaimed, demon god?"
