It's pretty average. With the lack of chapters, there's not much to say about this manga. I feel like it has a bunch of potential though with the wrong writing it could go down. The main character seemed to forget who he previously was and is nothing like his past life. It's interesting and has an interesting premise, so I'd give it a 7. Pretty decent.
Decent read so far. Nothing particularly outstanding for the genre, but we're only 6 chapters in, so who knows what's still to come. For now, there's magic, swordsmanship, generic bullies, incompetent braggarts, a slave girl, and a very OP MC.
I'd recommend it to: those who like the reincarnation genre, overpowered characters, and those looking for a much shorter version of the Legend of the Shield Hero.
