Welcome to Rokkenjima, @AMF! You sound like quite the veteran for both Higurashi and Umineko! Since you a veteran, I recommend checking out the spoiler threads, which are separated by Higurashi arc and Umineko episode! Of course, you can also talk about your favorite scenes for both Umineko and Higurashi, as well as talking about the moments in Umineko that have led you to crying. You can also talk all about your favorite characters, as well as the characters you are most similar to. We also have a Ryukishi appreciation thread, as well as a thread where we ponder what questions we would ask him if we were ever lucky enough to meet him.
Probably the best way to get involved here is to check out our tea parties! These are when we all get together and read (or reread) the Steam rereleases of Higurashi and Umineko! You can catch up on our prior tea parties by following along with the spoiler free threads or listening to our lovely podcasts (which if you want to help host, you can). The next tea party will probably be on Higanbana, so I think you should totally read along and post your thoughts in the Higanbana thread once that tea party is officially started! At the moment we are taking a little bit of a break from our tea parties, so now is probably the best time to catch up on all the past discussion! You can also check out our threads for Rose Guns Days, Iwaihime, Hotarubi, and TRianThology! We also have threads for all the latest news concerning Kai and WTC5!
Of course, there’s a lot of other fun stuff to do here too. We have threads all about gaming, Touhou, writing, reading, music, sharing your pets, even talking about pizza! You mentioned being an artist, so you may also be interested in looking at/posting fanart! There are fanart threads for Higurashi, Umineko, Rose Guns Days, Higanbana, and Hotarubi! And since you like singing, you might want to check out the “You” chorus that some of our lovely members participated in.
I’m really glad you could make it here! I think you’re really going to enjoy it here!
