I, the expert otaku, Cara, have examined over the years that there are many, many, MANY different types of otakus.
DUH!!!! Otakus come in all shapes (shapes) and SIZes. That's what makes otakus so wonderful! Even if some are idiotic with no lives, and have no respect for other people and just try to act Japanese, we're all very wonderful, especially with the brean (bratty + mean) trait!
Now I have this guide to help you all classify otakus!!! OTAKUS!!!

These otakus hide their VIOLENT side, but their VIOLENT sides are shown in the anime they like to depend on! This doesn't go for otakus who go wishy-washy with what they watch, this is just for the otakus who tend to like and watch VIOLENT animes!
How to identify a VIOLENT otaku by their tendency to watch AND love these animes:
-Shion no Ou
-Mnemosyne
-Higurashi no Naku Koro Ni
-Hellsing
-Murder Princess
-Blood +


Ways to identify a sweet otaku:
-Air TV
-Kanon 2006
-Clannad
-Any magical girl anime
