Akame of the Demon Sword Murasame wrote: Why are they doing only 2 chapters now? Because they have a 20 minute timeslot for the episode and they cover whatever they can, including any anime flashbacks that aren't in the manga.

Flashbacks in the anime are generally not in the manga, so this extends the episode and reduces the amount of manga coverage.

It's all dependent on what each chapter covered, as a single chapter can be between 5-10 minutes of anime episode footage.
