Quite bluntly, I'm sad that this manga started as a funny, unpredictable action manga and slowly became a mess where tension has been lost and the plot twists seem contrived now in chapter 56.
The sexual harassment fanservice played for laughs wasn't very funny as well.
Art was always good.
After a while, in my opinion, the story became too meta. The emotional and deep moments also weren't because they felt forced. All in all, I think the story slowly ran out of energy.
I still think that people should read this manga. It was greatly executed for the first 20 or so chapters. Have fun reading :)
