Wow a dj from 2006 translated today. A very good day to see, Made when the novels were still going even.
It kills me j-novel almost licensed the novels but instead went with earl and fairy saying modern yuri fans might not like Maria's type of yuri and that it is mostly already done from fan translations(it's not) and the anime covered most it (It doesn't.).
Actually, the anime does cover most of the novels, up to and including volume 27. There are some minor stories left out, but the mainline story is mostly there. The novels have been fan-translated until volume 34, but he translations vary wildly in quality.
Marimite is still one of my all-time favorites, even though the ending leaves me a rather frustrated.
