I was reading an interview with a author about her serialized story
『やが』も佳境といいますか、最終章と呼んでいいところまで到達しました。最後まで見届けていただけると……って、こんな「もうすぐ終わり」みたいな雰囲気を出してしまっていいのかな?(笑)。
So, in my opinion, I think it makes more sense if 章 refers to a story arc in this comment (the last one) rather than chapter, but when looking in the dictionary, the only meaning for 章 is "chapter" or "section". Does it really mean chapter in this context or can this word also be used to say "arc"?
Thanks
