Most sad anime

This is menma from an anime anohana, i recommend for you if you guys love anime, menma is a girl ghost who can have communication with her friend jintan. She died because an accident when she played with he friend. I think this is so sad movie. She be live again but all her friend cant see. Only jintan can hear menma. It because jintan make some wish.
If you watch this anime. Iam sure you wanna crying when after end this movie.
