Hey there,
first of all, thanks for the comment. It's much appreciated.
Well, believe me, in a perfect world, I'd have left Jun as she was (sans character growth etc.) but we're not living in a perfect world, so I did what I had to do.
However, I feel like saying that she's like all the others now isn't really fair, cause a) it implies that the others are all the same and b) it implies that Jun was nothing more than her young-ish visuals. She's still the same girl, just in a slightly more appropriate frame.
That being said, I'd suggest just giving her a chance, cause I personally feel like the change to her visuals wasn't detrimental to her as a character - it rather emphasizes her personality in my opinion. She has some more screen time in the next update, which hopefully can show that off a bit more.
Again, thanks for the comment, though. :)
