This is vastly superior to a lot of actual action manga, which just throw out special move names you haven't heard before as if that's supposed to impress you, even though they do nothing to build up why the move should make you feel any tension beforehand.
Honestly other than the coliseum arc, which was such a tonal shift from the rest of the story, this manga is well-written. I do think in a lot of parts the translation doesn't get everything across very well though.
