I will give it you from the end : THIS MANGA IS AMAZING !!! Really amazing ,and to be honest , I find it much more better than other long series like Naruto and Bleach . I know you may be shocked right now , but this is my opinion , and I will supply the reasons that let me say such a thing .

First of all, the story is not that amazing , but the beginning was so simple and unique in the same time , but what let me gave it 7/10 is the comedy scenes during fights and the ending , I mean that there is a lot of mysterious left : what happened with Shinpaku ?What is the past of Akisame ? Could Kenchi beat Fuurinji Hayato ? What about miu's father ? How did Shigure meet Tochumaru ? and a lot of other questions .

Ok then let's talk about "Art" , I don't think anyone has problems with the fantastic drawings Matsuena Syun san gave us >>>>>>>> so directly 10 /10 .

Now : about characters :
Apachai
Akisame
Shio
Hayato
Kensei
Niijima
Tanimoto
.....................( A lot of other GREAT characters )
Mannnnnnnnnnnnnnnnnnnnnnnnnnn , Isn't it obvious ?! Only the present of such great characters is enough to give this anime 7 over 10 ! Nothing else to say so of course 10/10
Enjoyment : 10/10
so it is very simple :( 10 + 10 + 7 + 10 )/4 = 9.25
