the manga have some good points : if u want to read manga with new ideas and don't spend ur entire life w8ing for its end i think this manga will be good options , the end is not legendary but it's good end , maybe some event at the end of manga aren't so good but even if we say they r 10 chapter out of 180 it is good manga too

i like the idea about making series with 150-300 chapter and had good end
the end was not so great but it's so good compared with another manga that had disappointed end like Beelzbub or bleach or Vagabond
on the another hand u had that endless manga is really boring for me
many kids have that idea "oh no i love that manga i don't want it to end forever" or "why he kill that character everyone should live to the end " will have bad thought about it
the only problem is that manga try to be Shounen and Seinen at the same time which give it more readers but with less points
