If the artist commentary uses a pun that does not translate well at all, how is it supposed to be labeled? For example, post #2204056 where 激想 is deliberately used as a pun on 撃槍 (both pronounced gekisou - a reference to "Gekisou Gungnir", a song sang by the portrayed character), but the reference is not found on the actual post and requires meta-knowledge of the series.
I couldn't find anything with a brief search. I assume the right thing to do here is to mention it in a footnote in the translated notes somewhere?
