No worries about translating from Chinese. Gintama stuff is so rare to get translated. I'm really just grateful we got anything at all. Well, yaoi Gintama stuff gets uploaded/TLd more often than the straight stuff. Which is cool - not knocking any genre.
But it's really nice to see a doujinshi that takes the canon(ish) pairings and keeps them, rather than pairing up characters (Gin is really like a Dad to Kagura, so those doujinshi are ok, just not for me) and also keeps the characters semi-true to their actual personalities from the manga. Kagura really does act like herself - so much so that the first half of the doujin is dedicated to the setup. Which I absolutely loved - it's a great blend and love of the characters shining through in these fan works that I find myself truly enjoying.
I absolutely adore Gintama, so thank you for doing this, truly!
