Post an Аниме that wasn't necessarily that sad but still made Ты cry или tear up.

Наруто and Gaara's past made me tear up (Naruto Shippuden)

Black Butler (Тёмный дворецкий) and Chuunibyou demo Koi ga Shitai ~

Yu-Gi-Oh and all it's spin off's

I just Любовь the series so much that I sometimes tear up whenever I have to say goodbye to a protagonist that I have gotten used to . I especially cried over Yusei and Yami , because I had a crush on them T-T

The last few episodes of K-On! made me cry so much. T_T

The scene where they had their last performance at the school together;
The scene where they cried and talked about what would happen in the future;
The scene where Azusa finally broke down and begged her only Друзья not to leave her.

The End of Kobato is soooo...QAQ *cry cry cry*

I got pretty teary eyed in xxxHolic and Kuroshitsuji.

Squid Girl particularly in one episode

Qualidea Code
I was shocked when Canaria Utara, Hotaru Rindō, and Mahime Tenkawa seemingly died, but it later turned out they were rescued by the real humans.

Unfortunately, Airi Yūnami wasn't so lucky...
