I like this.
It's a power fantasy in its purest form. Completely shameless, but fun.
Mc has no problem with killing men and women. Which is a plus for me since I'm sick of MCS that will kill a million guy minions, but the females will magically be spared or have some sad backstory even though they did the exact same thing random mook one or two did. Looking at you isekai manga.
There is no moralizing or virtue signaling, just raw unfettered scumbag. It's refreshing.
Oh, did the plot with his best friend from school that got screwed over and sent to jail ever get resolved? I'm at like 257 and there has been no mention of that.
