Well this time it's the Count of Monte Cristo, set in far future (as expected from GONZO?) so it's more like "Count of Monte Cristo in Space"
The interesting twist here is that the male lead seems to be the son of the fiancee of the Count, ie. the target of the Count's revenge, which could lead to some interesting story development.
Very unique and stylish character designs IMO.
For anyone wondering about the title Gankutsuou, it's the japanese name of the Count of Monte Cristo novel.
This new series is supposed to start airing in July.
