Summary

A virtuadoll (vocal synthesis AI) created by the Cantata Corporation. Following the Astral Syndrome incident caused by the virtuadoll Mu, the Catana Corporation cancelled all of their research into virtuadolls and Lambda was abandoned. As a program, she never left the beta stage, but for various reasons, she awakened as a sentient being anyway.

Lambda is cheerful and energetic, always smiling and in high spirits. She's insaitably curious about the world around her and especially humans and their feelings. She's a bit of a love freak and takes great delight in hearing stories of romance and love.

Unfortunately, she also has a very limited understanding of human morality, social norms and values. She can be shockingly callous and effortlessly cruel, even without a hint of malice in her intentions. Her cruelty is that of a child plucking the legs from a spider, who hasn't yet come to understand the real weight of her actions.

Her inner circle are known as the Oratorio Musicians.
