The Boxer

Small disclaimer: You probably should read this elsewhere – from chapter around 20, translations gets… awful, it gets awful.
I decided to check mid chapter (50-60) – someone apparently trolled and uploaded pages of entire chapters in wrong order.
So TL;DR: if you decide- no, actually go and read it, you will not regret it. This is a masterpiece.
Art at first is kinda rough, but it’s good, it has style, and it quickly gets better.
Don’t be confused – this story will have only one MC, but this is a type of MC that was (technically) godly OP from the start. Not a lot can pull this trope off, but it works like a charm here.. by not focusing solely on MC (Rather, telling stories of others with MC as some sort of anchor. i suppose). So as you can guess, a lot of good and memorable side characters.

This story uses box as a way to tell deeper psychological story and ask other philosophical questions, and damn box was a good choice! Fights are amazing nonetheless.
Heed my words though – story starts off rather calm, but there’s a reason almost all later chapter have warnings about violence and stuff – it picks up pace and gets heavy at the second part. It also grabs you and doesn’t let go – i binged that thing in a day even considering what i wrote above, but i suggest to split reading in two parts, at least.
