「狭義」の意味は何ですか
I don't really understand the translation of "narrow sense" or "strict". The most I can assume that it's being used in the same way as "strictly speaking"?

Here is the example I found it in-
「狭義には、「東方Project」とは、上海アリス幻樂団のメンバー「ZUN」が制作している同人作品の総称である」

Answer

Yes, you're right, 狭義には means "sensu stricto" = "in the narrow sense" = "strictly speaking".
