User blog comment:B214/Season 3 confirmed!!!!!!/@comment-179.232.68.37-20141214002810

Chronologically, they should produce the next seasons this way:

3rd - Volumes 5 and 6

4th - Volumes 7 and 9 (volume 8 has no drama, so they will probably skip it)

5th - Volume 10 and 11

I find strange the season end in volume 11, it would be a "Cliffhanger". For me, they should animate with 24 episodes, covering four novels per season.
