Once known as a self-centered and overindulgent member of Tearmoon Empire's royalty, Princess Mia's reputation led to her eventual imprisonment and execution. She woke up at the age of twelve with haunting memories of a gruesome guillotine and a tattered diary chronicling her squalid experience in a dungeon. The memories terrify her.
Consumed with the desire to change the course of her horrific fate, Mia resolves to change her ways. She reluctantly takes on a saintly facade, speaks on societal concerns before they escalate, and even shares what was once exclusively hers with others. Despite her altruistic persona, Mia knows her actions are mainly self-serving. However, she accepts that each good deed counts and sets out to improve herself, determined to change her destiny, one step at a time.
