i got into mangas when i was pretty young, my brother used to watch them, some of the best i've seen are the judge, which i can not find for sale anywhere, doomed megalopolis, wicked city, street fighter, devil man, amon, highlander, ninja scroll, there's loads more but i can't remember what half of them are called, it's been a while, i found a good site which you can watch alot of manga on, i recommend you watch wicked city and doomed megalopolis if you haven't seen them already, you can watch most of these on this site, only a few haven't worked that i tried
