Review Detail of S_A_N_0V in Highschool DxD: I have a Dimensional Travel System

I have read all 29 chapters, except "Alert", and now I can easily say that this fanfic is really worth my time I have spent on it! In addition, the mc's system is something new in front of all DXD fanfics, but the main option is quite the same(Increase power of mc to charm girls:>).
