Now, I don't like much Anime. I find the stories to be just a little too ridiculous a lot of times. I mean, a 17-year-old with huge boobies fighting demons and such? Come on!
In fact, Berserk's story started out simple enough as well, but seems to be a little bat-shit crazy now. However, I think it deserves this honor for keeping my interest for as long as it has. Who knows why? It's probably because of the intense/demented gore and dark themes.
The whole thing is about a guy with a giant sword that would put Cloud Strife's to shame. He also has an anger problem (but I'm glad they decided not to call it "Big Sword, Anger Man"). It goes through his young life as a soldier, then all Hell breaks loose later as demons are released onto the Earth. And they mean business.
Unfortunately, the Anime wasn't popular enough and they stopped making them, but I think the Manga is still going (haven't caught up). There was even a game out for the Sega Dreamcast I believe.
P.S. Got a girl's number from FaceBook. Thanks for all your support on that last post! :)
