I think mine is pretty straight forward. Ino is one of my favorite characters in Naruto, if not the favorite, and I just happened to join when Naruto was the main Anime on this website. I am not a huge fan of Naruto, but I still keep up with the manga chapters to see how it well end since I am already so far in.
Anyways, I usually have GuroxChan as my user name if not this. It means "Grotesque Girl", I am a huge fan of Guro (Not for the weak of heart to google), and naturally I got the nickname "Guro Chan" because of it. Thus, I use it regularly.
