This is Hitsuji's website. She owns the domain, and does the major unattended sections. It's a work in progress. It has all kinds of Involuntary Art (the definition of manga, manhwa, and manwha). There's things on individual artists, and although it might not be likeable at first, it grows on you over time. You can find out about other types of graphics novels, and learn about art that isn't appreciated as much.

This is Islevet Waterborn's website. She does the Togashi Shrine section. It's wonderfully laid out (very clever and seemless in fact) simple and fast loading. It is all manga-based and has a wonderful page to Takeuchi-sensei. It is very simple, but elegant and very well thought out. It really captures the spirit of the manga.

This is the Lunar Archivist's site. He's going to put a section on this website that will be the most complete Sailormoon Encyclopedia. Some of it will be repetitive, however, it will be searchable. It's really good for figuring out the background of Sailormoon, and where Takeuchi-sensei got her ideas. It's in association with Ken Aromdee's FAQ, only he annotates it more.

This is Nishi Rajan's website. She is doing one of the parts of Takjeuchi-naoko.com eventually..... (when she isn't so busy with getting married, and going to law school). She's a really cool person too. The website is another information website, with more interactive things in it, including the Takeuchi Naoko Mailing List. She also is having trouble finding a host, so it's not stable until then. (too much traffic).
