Lore Time
 
Twilight is not a natural dom at all, the only reason she is being a yandere is because she is incredibly afraid to be alone and to lose Anon so she wants to control him in every way possible and make him her property. As long as she is in control she feels safe but like this she has build up a wall. Nothing can reach her core. She should know that control is not going to make things better, the fear and pain will always stay deep inside. A long time ago somebody made the same mistake to think that control could somehow replace true love.  
 
Years of suffering easily makes you forget such things. Now it is up to Anon to break through and reverse the roles.  
But it is not as easy as taking her magic away and giving her love in her most helpless and vulnerable state. The insane fear she has inside could easily let the situation get out of control. You will get more lore on that in the future.
