Exceptional drawing, character building incredible, world building rather good (some really faint plot hole/ unanswered questions/ messy explications), flow of story rather good too.
The only flaw I would point is that the author stay too faithful to the basic Shonen developpement :
Be it the mysterious power of the Mc (which get explained later, but still), friendship power, the ridiculous power spikes and characters strength evolution which coincidently follows the enemy's evolution ect.
I think that if the author managed to get rid of those point, it would be a 10/10, for now I would give it a 8 or 9/10.
As we finally have comment section working I wanted to say thank you for your translation. It was an amazing series, thank you for giving as an oppoturnity to read it
