Well... uh....didn't expect THAT to happen to Villefort. Uh, so yeah, MUCH different than the anime.

Spoiler

And boy did it do a 180 where suddenly Valentine and her mom are basically dominatrixes and punish Villefort? Can't say I was a fan but whatevs.

So you only get to see him exact revenge on Villefort, which finishes up at the beginning of this volume, and then the rest of it is backstory on Edmond and how he escaped Château d'If and came in contact with Gankutsuou.

I really enjoyed learning more about the Gankutsuou and Edmond's escape, and also how the art in this started to become much more Japanese Horror-esque (think a smidgen of Ito). It deviates wildly from the original story of Count of Monte Cristo, but like they say in the manga, they wanted to do something different for the fans that watched the anime. Don't read thinking you'll get content based on the classic novel, do read if you are a big fan of the anime Gankutsuou!
