Otaku Zone is a forum based website to discuss anime and manga. In which a user can sign up for free and create an 'avatar'.
You can dress the person, give the accessories etc.
The whole idea of Otaku Zone is that people from other countries can discuss their love of manga.
It's highest user rate is from Eastern countries, and it is an English website.
A user on there would be called an 'Otaku'
Girl: DUDE! That cool kid in our class goes on otaku zone!
