I had a netflix account once and used it to rent anime. Several years ago I found a series that I liked, but never got to watch all of em. If I remember correctly there were several seasons.
I could have sworn it had something to do with Angel Cyborgs or just Angels, but the ones I can find (Angel Sanctuary…nope, Angelic Layer… nope, Battle Angel…nope) are all wrong. From my memory there was a boy in a castle or fortress of some sort and it seemed the series was sort of in the medieval times or something, but could be futuristic. For some reason I was thinking the father made her to protect the boy, but I am wondering if I am confusing my memories and conflating it with the Anime called Cultural All-purpose girl Nuku Nuku (or something similar).
I don’t think I am, but for some reason I do remember there was a bit of boobage, and I am not entirely sure it was a cyborg, it could have been a real angel or something.
I can’t find it, and it is bugging me now.
