Hello Chopin and thanks for your input. The somewhat turbidised manner of your posting is a challenge, but I reckon you are defending the placement of a comma before a closing quotation mark. I was just uncomfortable with the comma inside the quotation marks around a single word (Ronin), whereas the usage in the quoted text in your posts is agreeable/arguable.
