Yeah. Komga + Komf seems like overkill for your use case too. Komf would definitely get around the limitation of english editions only.

Readarr can track comics/manga too but unless you’re interested in only indexing by author I have found it less than ideal.

Tachidesk or sorayomi or whatever they are calling it now may be an option? Like the other tools I have mentioned it’s primary function is for piracy but I don’t see why you couldn’t just add sources and add series to library without downloading. Again would need dummy files to track owned vs unowned.

I use Komga + Komf for digitals but seems like you could do simply with mylar without a download agent. Might need to create a dummy file for each issue you own to change status to owned. Been ages since I have used so not sure.
