Nanael is the delinquent angel in the Queen's Blade franchise who would rather have her own harem of men and dominion on earth than to host the Queen's Blade tournament and/or investigate the Swamp Witch's minions. She is characteristically non-angelic and morally corrupt. While the series hinted at her corruption and follows through at one point she is redeemed and suffer nothing worse than a bad attitude and palette swap.
This one goes a bit further with a more extreme all-of-the-above demon corruption. A bit more graphic and extreme and time consuming. There is a direct sequel in the works involving her pal Hachiel (a more proper goodie goodie) Been in the works for about a month and a half...bogged down in complexity and non-fun.
