(at the time of writing, there are only 15 chapters translated)
If you're reading this series, I'll assume this isn't you're first jump into the "overpowered main character isekai" rabbit hole, as there are many others out there worth your time before diving into this one. So hopefully you know what you're getting into because there isn't much here that makes it special, or tries to change the formula. It's much more suited for when you've gotten through all the "good" ones out there and just need more of that ridiculous power fix. Why might that be?

Pros:
-The series is just fun. It's a kid who built up such good karma in his previous life that the world he's reborn in is basically made for him. The people around him don't question why an 8 y/o has this much power, and the world just accepts him as something special.
-The main character is STRONG. He has so much magic that he can cast basically any spell, and has access to any magically knowledge instantly.
-It's easy to read. Depends on what mood you're in, but you can just sit back and take in a chapter without worrying about the drama...

...which leads me to.

Cons:
-There is basically no plot. It's just meant to entertain by escalating the kind of crazy scenarios and good fortunes the main character gets into. There is no through thread connecting the chapters, no villains plotting in secret... (yet?) It's just whatever crazy thing the main character does that chapter.
-Everything moves SO FAST! There are time jumps aplenty, but you'll miss them if you're not careful. One chapter you meet someone new, then suddenly 3 chapters later the main character say's they met 2 years ago...
-The characters are all secondary. They exist to look at the main character and point in amazement at what he can do.
-The amount of them. It's getting out of hand, and very quickly. It's not too many side characters yet, but I just hope they stop adding in more as keeping track of them is the only thing I have to work my brain for going chapter to chapter.
-There is no action. Not necessarily a con, but it's an odd choice for this genre.
