What is the saddest moment you've ever seen in anime?

well, this is one of the saddest moments, makes me cry ;n;

:((((

Definitely has to be Hughes' passing from FMA in both FMA and FMA Brotherhood was awfully sad it was awful to see such a great man pass in the fashion he did.

When Hughes from FMA dies

Hm... Usually I have a list, but right now I can only think of L's death scene...

this </3

It's a tie.....

Grave of the Fireflies:
*Main character dies immediately. Flashback to his last days on earth.
*Bomb dropped, house destroyed.
*Kids find mother in a hospital wrapped head to toe in bandages. She dies.
*Relatives treat kids like crap. Woman nags little boy to 登録する military.
*Children become homeless, live in a cave.
*Sister (a toddler) dies of malnutrition.
*Boy learns that his father's plane was shot down.

Barefoot Gen:
*Bomb drops on town. Children, babies, & a dog are burnt up, liquefied, & showered with shards of glass.
*Main character loses his home.
*Caved-in roof crushes dads skull.
*Mother watches helplessly as her children burn to death. Stress causes premature birth of child.
*Boy starts to 表示する the same symptoms as a man he watched die of radiation poisoning. 安全, 安全です bet he has cancer now.
*Boy & adopted brother get jobs to buy ミルク for the baby because the mother has no 食 to make milk. The baby dies of starvation.

Wow animes can have some really sad moments, but I'll go with the ending of Code Geass R2

The death of Ace :'( it made me cry.

Ash and Pikachu's Goodbye

when Natsu's standing によって the gravestone he made for Lisanna in the place where they used to play as kids. all he says is "goodbye".

the last moment from Anohana
SPOILER ALERT!!

The ends of the 黒執事 seasons.

*Sees scene where Hughes dies in FMAB*
CHALLENGE ACCEPTED!

*Five 分 later, in fetal position, crying like a sissy*

Madam Red's Death in Black Butler I cried like a baby when they showed her flashbacks

There is absolutely no scene (other than the Code Geass R2 ending) that is もっと見る tear-jerking than this ending scene to エンジェル Beats.
(Though I think some of the feeling was ロスト with the translation and terrible dub.)

In an アニメ called Tokyo magnitude 8.0 its one of the saddest moments of アニメ ive ever seen, i cried through 2 whole episodes 40 min and then i cried もっと見る later 😢
