A heads-up!! The bad news: this story has a System. The good news: it's even more useless than the protagonist. The System is purely here to move the plot along. It won't have any overpowered gimmicks, and it won't assign missions or hand out rewards. The author promises once again that the System really won't have any overpowered gimmicks!!!! The story is mainly about the protagonist going from a true bastard to an utterly supreme being, one step at a time.
Introduction:
“Please, let me go... I don't want to die... Please, please, aaahhh...”
The gentle, refined junior sister, a part of himself...
He laughed savagely, looking at you like you were a mongrel. You begged him to spare your life. You didn't want to die, didn't want to die just like this...
There was still so much to do. You hadn't fulfilled her wish, and you couldn't let her down...
“Please!! Please...” You could only keep kowtowing, paying no attention to the savage, sickening laughter all around you.
