Is there a chance Asa hand gonna grow back? The wound from her hand being cut off most likely already heal since she is so chill about it which mean she has healing factor but somehow her healing ability is inferior compare to other hybrid that it can't grow back limb.
There also theory that she is different from other hybrid since unlike them Asa and Yoru consciousness coexist at the same time in the same body and she also doesn't have armor form like them.
