Have you ever seen Tokyo Magnitude 8.0? That was the first Anime to ever make me cry not once, but twice. Really sad ending to it. Was not expecting it at all.

Kanon 2006

I cried at the end of Hard Luck Woman.... Call Me, Call Me is playing in the background and Ed leaves.... I cry every time....

I got very emotional during Witchblade. It was just the fact of the lonliness and uncertainty facing 6-year old Rihoko

Full metal alchemist and code geass

Indeed, code geass had a very sad ending...:o

Clannad, Clannad After Story, Elfen Lied, Kanon 2006, School Days, Tonagura!, and Zero no Tsukaima

Did not! It wasn't sad for me. If you take a good look at the person under the cloak with CC, you'll see that it's Lelouch. He didn't die.

Elfen Lied is the only one to make me cry so far XD

Under what cloak?! xD Tell me more about it...
