I've read a considerable amount of ecchi manga with black haired protagonists trying to cope with his uncontrollable harem life. The twist is that this one out of many is seemingly the only black haired protagonist to truly embrace his dark perverted side.

This manga sticks out like Tomoki's wine bottle (reference), and is possibly one of the best ecchi/comedy/harems you will ever find and read in your entire life.

Every chapter brings on a creative new way to make you laugh, this manga does things with panties that you would never imagine in your life time. You won't believe some of the stuff you see, cause I guarantee you would never find it in manga anywhere else.

This is a must read.
