Sorry, Yuma. This is becoming a nightmare... Let's answer the question I -can-.
Dark Signers are the opposite number of Signers. To become a Dark Signer, you need to have... died, with regrets, or anger, or despair in your heart. These people are then revived by an Earthbound Immortal, and driven to oppose the Signers, more or less. They have dark power equal to the Signers at their disposal.
I should note that Alex is acting of her own free will. She doesn't seem to be manipulated by or using the power of her own Earthbound Immortal.
Alex was a Dark Signer once, years ago. But we'd solved the issue... until now. At the end of a duel we had, she... somehow made Rhongomyniad real, impaling herself on his spear. Reigniting her Dark Signer powers.

As to her motives... I can only speculate.
