What anime series have you found to be emotional in one way or another ?

I 3rd Shigatsu wa Kimi no Uso. It reminded me of a couple Jdramas I watched a couple of years ago. Some of those can give you the feels hard. Steins;Gate as well, Plastic Memories, One Week Friends. These are all recent shows I'd have to dig through my memory think of any older shows. Also Gintama can make me care about some random character or moment at anytime. Like once when a character falls in love with a strange creature they're supposed to eat, or the lives of a toilet paper maker and his son.

Koe no Kitachi Angel Beats Blood+ Clannad After Story Kimi ga Nozomu Eien Phantom ~Requiem for the Phantom True Tears (Best girl never wins.) To name a few.

Cried buckets over the anime adaptation of Kimi ga Nozomu Eien. I really want to play the game >A< Your lie in april was a bit sad too but I didn't really cry over that. Boys be I cried a lot too.

Madoka Magica I literally just watched this a second time with a friend and I got choked up multiple times despite knowing what happens. Trigun No matter how many times I see the last four episodes, they always get me misty. I'm very much a pacifist, and the idea of taking a life, even when it seems like the best option, is really upsetting to me; so I can empathize a lot with Vash. One Piece The early episodes take me back to my first year in Japan and get me feeling really sentimental. Also, the moment when Nami asks Luffy to save her after everything Arlong put her through always got me right in the feels. I kind of stopped watching the show later on, but I have some great memories of time spent with friends marathoning parts of it, playing drinking games, or even going to the Baratie restaurant in Japan.
