Vivy: Fluorite Eye's Song

Vivy, the first autonomous artificial intelligence, works as a singer in a theme park and believes her mission is to make people happy through her voice. Her repetitive life is interrupted by Matsumoto, an AI from the future who warns that machines will begin a war 100 years later and wipe out humanity.

Preventing that future requires Vivy to alter key events across an entire century, even though every intervention can create consequences Matsumoto cannot fully predict. As she saves lives and watches human generations pass around her, Vivy also begins searching for the meaning of singing "from the heart," a phrase that is difficult for a machine created to fulfill one fixed purpose.
