This manga certainly has some issues with how it portrays fight scenes, feel like there's a lack of proper motion or impact in most fights, but you can't deny that it's still damn entertaining
If you go through the panels carefully, it's obvious that the artist is condensing the action down to the minimum possible drawings, and often just implies a lot of what's happening. But I agree, I think this is a graphical medium, and the action scenes could use a bit more room to breath.
On page 652, I think the translation should be:
"This happen probably because I've done it too much" -(sex)
"If the opponent turn into a mess, it will scare the villagers"
"That's why I didn't want to fight..."
It could be wrong. Thanks for the translation.
My original draft was something like
"If I fuck up someone too much"
for the first line. You might be right about it, it wasn't super clear to me who the subject was, but I think what I ended up with keeps the flow of the story well enough, so I won't correct it. Thanks for your comments though!
