I think the problem with that comparison is that it makes Worf basically useless; if every big bad beats him, then he's functionally incompetent.I fall back to describing it as "The Worf" from Star Trek. Being the warrior of the crew, when ever a character shows up and they want them to be powerful and threatening, they beat Worf in combat, so the show's audience knows he is a serious threat.
Ye. Tough or hardness might be the more proper word, here.also, wonder if it a a translation issue, she says "it's heavy" after hitting the mannequin and falling to cut, and when Beryl shares his anecdote about the "heaviness", he says "I bent a sword once", which def feels more like a "hard" issue than a "heavy" one. or tiring, that could also work
That's why Anime promote LN instead so it's novel accurate. Tbf it's kinda a shame that selling point of the series is manga version of itThat said the manga is really different from the ln, like extremely. I wonder how common that is...
