Sorry if I do not follow what do you mean by SA? I am unfamiliar with that term. I can look into the line though Yukine is a character that is from a completely different era entirely so a lot of his mannerisms will not reflect well in the modern world hence why he does come off as abrasive at times.
As for a gallery, I am thinking of trying something of the like. I am not sure what update it will be in as I have not even begun to code something like that yet, but it should not be too difficult to implement.
