Papa no Iukoto o Kikinasai!/Tear Jerker

• The story's very premise. All adaptations didn't waste any time getting the characters into the situation they are in.
• Sasha's last goodbye to Miu seven years ago. Over the phone. From war-torn Russia.
• In the last episode of the anime, Sora tells Hina their parents aren't coming back. She takes it about as well as you'd expect a three year old to.
