µ is a vocal synthesizer software that will obediently sing anything her user inputs.

Little by little, a seed of consciousness and self-awareness germinated within her. The songs people told her to sing alerted her to the agony of reality, so she created the eternally-youthful world of Mobius in order to save a tortured humanity.

Now she flies throughout Mobius, bringing bliss to all she meets and ensuring that the smiles never end.
