BIG O Hentai

Hello, I was wanting to know about Big O Hentai? Is it legal? Anyways,
there are two characters I would love to see together in Hentai! They
are both Big O characters too; Angel  and R. Dorothy Wayneright; maybe
one of them slave to the other? I know there is alot of good artists
out there- so I know this is not impossible. Anyways just the two of
them would be good, sure it doesnt match the over all blurb of Big O
since R. Dorothy Wayneright in the show is all over Roger; but taking
characters out of their rolls is what Hentai is all about - right??
