The
previously announced Code Geass: Heroine's Tribute art book has now been officially released in Japan! & boy, is there some great art in here of everyone's favorite Geass girls. Surprisingly the two main girls, CC & Kallen, don't totally dominate the book. Plenty of the other female cast get their own nice works of art as well. But with myself being a Kallen fan, I'm still glad to see a good amount of her in it (including a very nice one done by the actual anime staff as opposed to a guest artist).
I was also surprised to see my other favorite character, Anya, get a total of three different works. Quite a lot for one who leans more towards minor than main character. Kaguya would probably be my third favorite, & she shows up quite a bit as well. Check out some very high quality scans of the entire art book here:
