"Existence is no longer a free right. It is a privilege, a reward... a crime." After witnessing her father fail to claim his rights to exist and knowing the truth behind her mother's disappearance, Arian Benedictus Zhu became a rebellious child whose sole purpose is to destroy the Superior Courts of Mankind's Life and Existence. She is trapped in a world where gods and goddesses have dominated the world of humans; a world where a person can only exist for two decades for free. After which, every mortal must go under a trial every decade in front of the deities to narrate how "proper" they have been living and defend their will to exist. There are six lower deities: Goddess of Time, God of Emotion, Goddess of Kindness and Love, God of Honesty, God of Mercy and Forgiveness, and Goddess of Universal Affinity. Seated inside the Higher Court of Existence is no other than the most powerful and divine Goddess of Existence, whose final verdict determines a mortal's fate. There are only two verdicts: worthy or not worthy. Failure to obtain a worthy verdict from the Higher Court of Existence immediately ceases a mortal's existence and he is wiped out from mankind. However, there is another option that Arian Zhu is tempted to take. She wanted to rebel against the Goddess of Existence, to wreak havoc at all costs against her power. She would rather kill herself than allow the deity the satisfaction of convicting her not worthy of existence. There is one choice that she could accept that would save her from the verdict. It is the highest form of all crime and a death sentence just by even considering it. Arian had to become a Thief of Existence.
