Akame ga kill zero is the prequel of Akame ga kill and it's main idea is to show the complete story of Akame and her little sister - Kurome. However, there is much more than that showed in the series, there are various groups of new and old characters to be observed, a more detailed look into the mindset and ideals of the rotten Empire and in general a better and more detailed exploration of the dark fantasy world of Akame ga kill.

STORY
The story, as mentioned, is focused on Akame and Kurome - the series start since the very first day the Empire got their hands on them and follows how they struggle and change their mindsets towards the whole Empire situation. It gives a different perspective than the one showed in the original series since the focus is not on the Revolutionary Army, but on the Empire and their different assasination units. To be honest I expected the manga to be shorter and just expand on the past of Akame, but it turned out it is way better and rich in terms of information revealed and past of certain characters. It is the perfect addition to the world developed in the original series.
There are several different arks focusing on different aspects of the series and slowly progressing towards the culmination point of Akame's self-consciousness. Well developed and fitting perfectly to the original concept of Akame ga Kill.

CHARACTERS
The main characters are naturally Akame and Kurome. We are not showed much from the main characters of the original series, but several of them do make an appearance and seems like more of them are yet to appear as well. Esdeath and Chealsea seem to be playing a major role in the storyline and several of the Teigus the characters from the original series used are in the possestion of different people. This gives me the idea that there will be huge fights to retain those Teigus.
The new characters are also really interesting to observe and have unique personalities. The Empire is also showed as the rotten, twisted mess in a great way and there is huge focus on characters supporting the Empire, their mindset and goals.

ART
As expected, the art is on top level. I dare to say better than the original series, good attnetion to detail and fair amount of horror scenes (as well as a fair amount of ecchi and fanservice to balance it).

ENJOYMENT
For me personally, the series are quite enjoyable. I love the fact that the world of Akame ga Kill is expended and developed even more, there are new great characters and old ones are not neglected as well. The storyline is engaging and even tho we have an idea what is going to happen there are enough twists and surprsied to keep us engaged.

8/10 (So far)
