Looking for VNs with 'formal' vocab

(Sorry if my english is wrong)

Hello, I have been learning japanese on my own for a few months now (Reading Genki, WaniKani, PDFs, etc) . My main goal for now is to reach a good level to use Visual novels (In japanese of course) with Yomichan + Textractor to learn new vocab.

I have been reading about this on the internet and many people says that Visual novels often lack normal vocab or they use unusual vocab.
Is there any Visual novel with formal vocabulary and that you would recommend?

Thanks.
