Brief shocking depiction of a corpse with flies and maggots. No exposed musculature details nor bone.
At the climax, an explosion causes a character to lose a limb, though this is depicted symbolically. We see the bandaged stump afterwards.
Mass death, including children, due to wartime bombings.
A character's bloody stump from a missing limb is briefly shown. While shocking, the depiction is not very graphic. It depicts tattered clothing and blood. The skin is depicted tattered in the same was as the clothing, and the interior flesh is slightly darker, but not in detail. No depictions of musculature nor bone.
Briefly, a dirty man with darkened skin, indicating non-graphically that it is burnt, is seen sitting in the background. He is later confirmed dead. It is unclear if he was already dead at the time he was shown on screen. It is equally unclear in the source graphic novel.
