Well I'm a BIG fan of GTO, maybe because it was my first anime serie I watched but I still like, have rewatched it many times, bought the anime DVD's and now reading manga.
I have readed from 1-18 and waiting for more... In my country I can't buy all the mangas, they have only from 1-19 here...
(more will come but later and I'm ADDICTED!)
Well it's sad to see that Onizuka is virgin still
And I think the manga has one of the world pervert-minded characters, Sakurai (that english teacher, some people messes him with the chairwoman).
