vivy

Vivy, or better known within series as Diva, is the protagonist of the original tv anime Vivy: Fluorite Eye's Song. She is an android that possesses very long blue hair with an ahoge, blue eyes, and on the left side of her neck a glowing circle with an inverted triangle that is indicative of androids within the series.

Diva is a songstress AI and is the first autonomous humanoid AI. She was given the mission to make everyone happy by singing with all her heart, though she struggles at grasping how to accomplish that. Diva's first fan, a young girl named Momoka, gives her the nickname Vivy after the princess in a children's picture book who looks like Diva. Shortly before Diva's first birthday she meets the future AI Matsumoto, who takes control of the body of the teddy bear that Momoka gave Diva as a birthday present.
