Hi! You might have already found out where the manga picks up from the anime by now, but just in case this comes up in the future what the hay. 8)
The anime deviates from the manga after episode 65. From there you can pick up Vol 7. I'm not sure what chapter exactly. (Probably Chapter 2 of Vol 7)
Also for those who wants to know what part of the anime follows the manga Ep 1-19, 38, & 52-65 (I might have missed one omake from the manga, but it has nothing to do with the main story.) Happy reading. 8)
