Hey there, the name is Sei003 and I just joined up today. I saw your Interest Check and thought I would give it a shot. I am especially interested in the BrotherxSister, AlienxSpacer, PetxOwner, and SlavexMaster pairings...though to be honest, I am okay with the vast majority of what you put up...and as far and fandoms go, I would love to try the Chobits one but only since I am not really familiar with the others...other fandoms I am into are: Naruto, Digimon, Kaichou wa Maid-sama, Detective Conan, Inuyasha, Fate series among others. 

Let me know if you are okay and we can start asap. And yes, I am totally okay with the 18+ thing.
