Realizing this, Pride uses her skills and knowledge of the game to become a compassionate and benevolent ruler. She hopes that by changing her ways, this will lead to a better future for her kingdom and the people around her.

The current Pride uses her memory of the original timeline to save and protect everyone that would have been abused by her; unintentionally causing them and herself to have glimpses of the original timeline.
