>On a side note, my favorite so far is Shiranui!
Ultra based.
In my opinion, the best starting point is Taimanin Asagi The Premium Box. It has most Taimanin visual novels in one package.
I don't know about OVA's, i mean, i watched them when they were coming out, and they didn't make me care about Taimanin back then, but i need to rewatch them to judge properly.
