I've watched a lot of anime.. but none have ever made me cry. I guess the ones that brought me close...ish were Naruto, Death Note and Blue Exorcist (when Shiro died).
...step door step, hart-, hart to heart...left right left...we all fall down...like toy soldiers... bit door bit...torn apart...we never win...but the battle wages on...for toy soldiers...
I'm being honest with u here, in all my searching I've never seen an anime that made me cry. In fact, when people die, I usually laugh, cause I'm just twisted like that. HOWEVER!! Air and Angel Beats came pretty dang close.
[EDIT] Well, I just watched episode eight of elfen lied. It took every ounce of my strength to keep from bawling my eyes out . . .
Fruits basket is the first anime that made me cry. Fairy Tail and Clannad also made me cry, and once I was having a terrible dag then one of my fav characters died on Dangan Ronpa, so i cried.
One of the only two animes that made me cry. Fullmetal Alchemist: Brotherhood was super sad. I cried when Envy killed himself (Envy was my favoriete character, let alone favoriete Homunculus), I remember watching it late at night and just bawling my eyes out into my pillow.
The seconde anime that made me cry was Death Note.
Well ya see..... I admit it: I cry pretty easily in anime, though I've been getting better. However, the ones that made me full out BAWL are the following: Angel Beats! Code Geass Romeo x Juliet Death Note K FullMetal Alchemist: Brotherhood MAR: Marchen Awakens Romance (The first three I consider to have the saddest endings that I know. Angel Beats! made me cry at least three times.)
1. Kobato 2. Anohana 3. Kyoukai no Kanata 4. Ojamajo Doremi (More like the last episode, man i hate endings DX but it was so good) 5. Hunter x Hunter (Tears of overwhelm happiness count? I mean Gon and Killua's friendship is just the greatest thing ever. Like u guys can't understand DX precious babies would do anything for each other. of the friendship with Leorio and Kurapika too.)
Naruto has made me cry oh so many times.- Naruto crying after Jiraiya dies-Itachi-Obito-When Kakashi dies fighting Pain-etc. Fairy Tail made me cry soooo much after Acnologia
