I haven't actually read those yet, though I've got them both on my Reading list! LoL I've seen the anime for Ghost Hunt and I have to agree if she's like the anime then manga Mei will definitely end up on the list!
Have you read Ghost Hunt series and Shinrei Tantei Yakumo series? I think in both of them (which ever version you read) female leads are strong in their own way. I tried to find them in the list.. Sorry if I missed them. ^^'
Also.. Check Kieli if you're interested/haven't done so.. I'm not sure where does she count in. Manga cuts a bit short what is a shame.
