So I am a fan of DxD, my favorite part of it is the Evil Pieces because I think they are pretty amazing for something that uses both science and magic.

But what I'm wondering, is what happens if the master dies? I was wondering this after Issei's death, and how his returned and no longer worked. So what would happen if Rias were to ever die?

1) The reincarnated devils stay as devils, but their powers as Evil Pieces become void.

2) Without a master, they would become strays and/or up for grabs by any Devil who would take them.

3) Nothing at all
