If I use the Ankh and manage to kill the final boss, who gets credit for the kill

The Ankh item works this way: when you are killed it instantly teleports you to the previous room visited, turning you into ???.

If, while in this state, you manage to kill Satan/Isaac, who gets the credit for the kill, the character you choose or the Blue Baby?
