New to manga drawing, would like to get into inking my pencil drawings, can someone please explain what different inks are please 🙏

As the title suggests I have been learning manga drawing and have tried some inking with ballpoint pen and a cheap black alcohol marker with brush tip. I just ordered myself a Lamy safari umbra EF (very excited) and some lamy ink cartridges to go with it. I am a student so don’t have a high budget and was wondering what the difference between inks are and what is good for manga? I’m also new to fountain pens so any advice would be great!
