This is just speculation, but perhaps "sword master" is written in japanese in the original chapter, and "weapon master" is written in english, so they don't understand what it means?
The translation is quite bad…
Some examples:
"I'm even hiding it from him" > who is "him"?
"you was shocked to see the smell under your armor" > "you was"?
"I started to worry about your stench" > wrong subject
"The smell was disappears"
and so on…
Thank you for the translation! Also, to the other readers, don't forget that you can block uploads from Manwhafreak so that they don't appear in your feed.
