Review Detail of Zetsway in Reborn in DxD; Lost in a poorly remembered anime world

To start with, I wanted to read at least 5 chapters before a review...I only got to 4. The start is only a summary of what the first arc of this is supposed to be. Like, the MC got reincarnated, got his cheats, grew up and moved to Kuoh. That's the start in a nutshell. No descriptions and no dialogue, only a summary. The MC is something that most are probably very familiar with. He's the standard emotionless, edgy, bored and doesn't care about anything type. The usual MC of dropped fanfictions. He 'knows' that he's the center of the world, and is also good at everything he does. Dude is developing his own game at 17... The other aspects of the world are not really see in the 4 chapters I've read, but somehow it feels like the author doesn't really remember the source material so it's bound to have mistakes.
