Saddest animê deaths. But don't post any spoilers about who or how.

Saiyuki Gaiden OAVs: I went into this knowing they'd die ahead of time, seing as it's a prequel to a show about their reincarnations, but I still cried.

Grave of the Fireflies: If you've seen it once, you probably break into tears every time you hear the laughter of children at the beginning of the movie on subsequent views.

Barefoot Gen: A pretty harsh thing for a kid so young to have to see.

Kodomo no Omocha: You'd never expect the 1st season of a high energy comedy to end with the death of an important character.
