I cry in so many anime but I rather just post a few.
Naruto, well because of all the characters dieing.
Death note, I think we all know why anyone would cry for this one. Unless you never watched the whole series.
Gunslinger Girl, at the end, very sad.
[spoiler]Dragon Ball Z, I cried when Trunks died, he was my fav character.[/spoiler]
dnangel, at the end.
Wolfs Rain, this one was a real tearjerker through the series.
Ouran Host Club, it was so cute but then it ended, it made me sad.
Othello, a manga that had a good and a sad ending.
Blood+, characters I liked died and the ending was sad.
Gundam Seed, a lot of conflict that made me sad and how the story turned out.
FMA, too many characters died, and ending was sad.
Cowboy Bebop, seriously, that should have made everyone cry at one point.
S-Cry-Ed, I watched every single episode but at the end it made me sad because it was over.
Samurai Champloo, ending is sad to me.
Loveless, I didn't really like how it ended but I still thought it was sad.
Spirited Away, it was too cute and the ending made me cry because it was so good.
Witch Hunter Robin, ending is tragic, but it was a good series.
Ok I'm stopping now, but I still have so many more that made me cry T.T
