Noire

The CPU of Lactation. The classic definition of a tsundere. Somewhat cold on the outside, she does care for others.

She is usually the one that has to most often put up with Neptune's antics, which doesn't help when she is kind of a workaholic.

Despite her serious exterior, she actually has a secret: she likes cosplaying. Of course, it isn't really too much of a secret, but still.
