this is one of the few manga I'll give a 10/10 despite the glaring flaws, the art is on the worse side, the characters are nearly irredeemable, the entire concept is just twisted to the point of disgusting, yet this manga holds a special place in my heart. What started off as a perverted comedy then became a dark essay on envy, finally transformed into a lesson on human psychology. Without going into the details it's difficult to explain exactly what is so special about this manga, but I'm sure that anyone who stuck out the 31 chapters will agree with me that this manga has some of the greatest character development I've ever read. Onani Master Kurosawa more than anything is a story about a flawed boy who breaks himself through the burden of his guilt, and just when he is completely irredeemable is when he surpasses all expectations.
