Nearland—an Artificial Intelligence theme park where dreams, hopes and science come together. That is where Vivy, the first-ever autonomous humanoid A.I. was created. Vivy acts as an A.I. cast member of the establishment and spends her days singing on the stage, following her directive to “make everyone happy through song.” Even though she hasn’t gained much popularity yet, Vivy vows to fulfill the mission she was given, and aims to one day stand on the main stage in the park where she can sing her songs wholeheartedly.

One day, an A.I. named Matsumoto appears before Vivy. It tells her that it has travelled from 100 years in the future with but a single mission—to work together with her to correct history and prevent the war that will break out in 100 years between A.I. and humanity.

Each charged with different missions, in what way will their encounter reshape the future? The A.I. diva Vivy’s 100-year journey now begins and the fate of humanity rests on her and Matsumoto’s resolve to destroy their own kind.
