Guts from Berserk. First page of the manga is him screwing a demon. Shame that the mangaka takes his sweet time releasing chapters and has been writing this manga for the last 20 years and is only 36% through.
I'm not! I've actually been milking it for the past few years because it's so good and Miura is so slow coming out with new volumes. I'm dreading the day I finally catch up and have to endure the excruciating wait for the next volume lol
