Black Mokona. The gemstone in its forehead is blue, and so is the sealing pendant in its left ear.

Its personality is less enthusiastic than its sibling's, but it's also a teaser. Also, it's quite a glutton.It doesn't seem to have as many powers as Soel, but it can do things the other one cannot, such as seeing ghosts. Considering Watanuki's around, that's rather convenient.

We see the best of this Mokona in the XXXHOLiC series.
