The anime doesn't directly follow the manga, especially at the end. Chapter 39 shows a flash of the Seraph of the End experiments Mika saw all these years, which demonstrates why he's been so worried for Yu. That was left out of the anime, but the anime otherwise mostly follows that chapter. The battle at Nagoya Airport starts with chapter 40, and I honestly recommend reading the manga version of that battle because there are several differences between it and the anime, especially before Yu gives up his humanity. This was the point at which the anime caught up to and surpassed the manga.

If you have no interest in how that battle really took place, you could begin reading at the very end of chapter 41. The anime diverted completely after the time-skip.

These chapters take place in volume 11, which came out in English on Tuesday.
