They read like the titles of Chinese webnovels (which have a mixed bag of conventions, but this sort of title (which reads much more concisely in Chinese) is pretty common, especially in the types of novels we might call LitRPG here in the West), which makes me wonder if they aren't adaptions of webnovels? I don't know how recent it might be as I, ah, also haven't watched much anime since YoI. Too many things to watch and never enough time!
