My main collective is Shinshoku.net, but I also own Asukira.net, Haptism.org, and a few others that are still mostly in the works.
I enjoy discussing deep characters and things that are not really obvious from the surface, and likewise, I enjoy reading shrines that offer unique approaches and different opinions. Most (spoiler: ALL) of my current shrines are to anime/manga subjects, but I do plan on making some to novel characters in the future; I just need to get myself off writing my thoughts only on tumblr, and organize them into a coherent shrine structure.
On the side, I do own a lot of fanlistings, and some of them I still carry hopes of turning into shrines. I guess only the future will tell!
