Ayashi No Ceres

Centuries ago a man stole a hagaromo(feathered dress) from a Tennyu(Angel). In doing so he stole her power and forced her to be his wife.

They were both reborn to fight each other today and race to find the original Hagoromo.

This is a great series, even if it's a little heavy on the melo-drama and pretty boys. Lot's of characters with different motivations and it throws in a plot twist now and then.

Take a look if you get a chance. There should be a link on the link's page about how to find it on IRC.
