tl;dr: A manga that has less depth than a sheet of paper but still manages to be reasonably enjoyable.

To be clear from the outset, the plot of this manga is incredibly weak and also very clearly just thrown together at random, especially the ending. The characters are also incredibly flat and not developed all that much at all. However, despite that, the core premise while super basic and pretty generic is implemented in a pretty interesting manner.

The foundation of the manga is lucky pervert situations. What makes this manga better at this than most manga, is that these situations are generally a bit more elaborate than those found in other manga, and also that the lucky pervert is actually a pervert and appreciates the situations rather than just being flabbergasted by them, which you would expect to be common considering the trope is called lucky pervert but is surprisingly rare. This combined with the ninja centered plot that provides a good amount of variety to situations through ninjutsu and such, the characters being decently likable, the comedy being pretty solid if repetitive throughout, and art that is quite nice to look at, results in a manga that moves at a good pace and is pretty amusing from beginning to end.

The ending itself is clearly one that came about as a result of being axed as it has plot holes so obvious the author attempts to smooth them over had little effect. Still, it in concept is a solid way to end, though unfortunately one that's overly rushed in implementation.
