Sigma. A name like that is usually only given to prime field devices. But, she might as well be one. That brain decaying in that cold metal skull is the only organic part she has left now.

Sigma was a test subject, bought by Relius Clover as an experiment to see if humans could use the Murakumo system. That experiment was thought to be a failure, until now...

Sigma may not appear human, but inside her metal prison she is, and she has the will to seek what she desires. However what that is isn't clear, and she doesn't seem to want to leave this body anytime soon...
