So I don't see many reviews, and none of the last year where the manga has gone through its best arcs so here is my review.

Story 9
The story is about akame when she worked in the capital, it goes through her missions with her old squad along with how she got her teigu, how the imperial was before she joined night raid and adding an immense amount to the lore. This answers questions about the lore and akame ga kill's story, by adding to characters that were introduced in the original akame ga kill like esdeath and chelsea along with other characters.
Story is rich and every arc up until chapter 42 was new and refreshing along with having the same akame ga kill feel but even more refined. I would say the Oarburgh clan arc is one of the best arcs even comparing it to the original akame ga kill in my opinion, its my second or third favorite arc in the entire franchise and this manga is worth it just for that sole arc, not that the others disappoint.
Art 7.5
The art is really great, but there is one chapter(13) where the author just puts rough sketches for half a chapter. The manga took a small break after that but I remember reading it and thinking "how did they put this in?" but besides that, the art does its job and is average to great depending on the chapter.
The character designs are great, better then the original akame ga kill even, and I really enjoyed them.
Characters 9
There were big shoes to fill in for the new characters, and they did it pretty well. It takes some time to get attached but the character development is spot on in this series, especially with akame. I can't explain without spoiling but its great to see her slowly mold into the person she was in the beginning of akame ga kill. We also learn more about characters portrayed in the original akame ga kill, and see their development as well. The new characters especially villains are done well and are made more interesting then just I am evil or deranged, which akame ga kill had some villains like that.
Enjoyment 10
Honestly, this is just biased since I am an akame ga kill fanboy, but to those who already read akame ga kill, this won't disappoint you. Anyone who likes a serious shonen or the original akame ga kill will love this manga.
Overall 9
This review was made at chapter 47, and so far the series has drastically improved every arc and couple of chapters so I have high hopes. I may alter the score and update this review as the series goes on.
EDIT After finishing this series I still think its close to a 9, probably an 8.5. The end feels a bit rushed but I really do think this holds up to the original akame ga kill for sure.
