Angels (etc.) in anime...?

[Jorlem]

Pretty much everything directly related to the Book of Darkness from Nanoha that didn't stick around might count. The Guardian Program drew heavily from the Beast of Revelations, and when Hayate synced with the original Reinforce, she basically became an angel (archangel? I can't recall how many wings she had). Also, the number of the Book's pages was 666, so yeah...

Madoka Magica spoilers:

Also, Madoka, in the finale, and Homura in the epilogue.

Also, Father in Full Metal Alchemist

Spoiler

(He's sort of a bit of leftover Primordial Darkness left over from the Kabbalistic story of creation. Basically, as it was explained to me, the story describes God as being everywhere, then retracting into himself to make from for the universe, then letting some of his Light leak back in. Father is a bit of the Darkness that remembers the Light, but never was touched by the trickles of Light God used to create everything, so he wants it back, which is why the series happens.)

The Sins would probably count as anti-angels, following that.
