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 rejoindre 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 montrer the same symptoms as a man he watched die of radiation poisoning. sûr, sans danger bet he has cancer now.
*Boy & adopted brother get jobs to buy lait for the baby because the mother has no nourriture 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 par 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 Kuroshitsuji seasons.

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

*Five minutes 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 plus tear-jerking than this ending scene to Angel Beats.
(Though I think some of the feeling was Lost with the translation and terrible dub.)

In an animé called Tokyo magnitude 8.0 its one of the saddest moments of animé ive ever seen, i cried through 2 whole episodes 40 min and then i cried plus later 😢

Qualidea Code(anime):
When Airi Yūnami died...
:'(
