So only read up till the second floor part and I had stop at there, I do plan to read it but not anytime soon. The series has two different artist, the first artist ended the series and the new artist took over from there. The art of the first artist was great and I like his Asuna's design while the second's was different but it is still acceptable. I know this was because I had seen the designs of the second artist hence I was able to tell the different there are more difference for sure but I did not had the time check it all out.
