Often times we were looking at the fantasy trope nowadays about heroes, but how about we look at the way around? Instead asking how powerful heroes are, how about asking where that power come from? How they obtained such unbelievable power? This manga with classic western tropes of fantasy manage to bringing grim world from other perspective instead showing you heroic action to save humanity this time they slapped you with reality the demon kin must face of brutality of war. I understood how many people didn't like the manga because how many characters ended up as Cannon Fodder, but the impact to the characterdevelopment of main character was quite powerful.

I wouldn't say this manga was good perse but the quality on how each fight felt so real and how many those Cannon fodder was real makes me think, "despite of all those trauma, he yet can obtained his best part. I admire this strong will unlike me"

Kuro no Maou was the hero the world needed but don't deserve as the proper Hero.
