some of my fanfics:
Refractions (madoka magica) - No matter how one would attempt to keep things the same as they used to be, the bending of a "law" would inevitable cause changes in the direction of their world, and that in turn would refract back to the their very lives, in ways that she never expected.
Reversed Connections (BRS) - reworked the structure and a mix of anime/OVA, has the Otherworld selves replace their human counterpart in the real world instead of the normals taking control of the Otherworld characters.
