We are a collaboration between two young musicians and amatuer UTAUloid producers.
Yin manages all of the online resources for the pair. If you end up talking to one of us, it's probably her. She also manages the UTAU side of things: She handles the tuning and mixing aspects of the vocals, and writes lyrics sometimes too.
Yang doesn't really deal with online things or youtube on our behalf, mostly because he's busy all the time. He composes the musical aspect, and occasionally writes lyrics. We're planning on recording an UTAU using his voice.
And before you ask no we're not a couple.
