From a technical standpoint, no. She has one (Arcus Diabolus: Bolverk), while she is the other one herself (Lux Sanctus: Murakumo). Well, more precisely she is it's core.

Nox Nyctores are made from 3 components: body, core and program. For the body, it's usually utilized something that can interact with the Seithr. The core is created by compressing seithr to it's maximum threshold, forming a unit (at the size of an apple). For the program they utilize a soul.

Now, since they had no means to compress the seithr (only Snap Weapon: Infinite Gravity spell or a completed Liquid Theory of Seithr could do that), they had to use a bit different core. Instead of seithr compressed to it's maximum, to the size of an apple, they used a lacrima of seithr at the size of a human, in other words, a Boundary Interface Prime Field Device. As the program they used the soul that can grow in them (like by entering the boundary). As it's body, they used the armor that is made from a special metal called Hihiirokane.

That is, more or less, how it is made. Of course, there is another step necessary in order to complete the Murakumo Unit. That is incorporating the Azure into the Nox Nyctores. In essence, a perfect and completed Murakumo Unit, is the Kusanagi.
