So, I was just reading about the stuff in Japan, and I got reminded of anime.
The anime takes place in Japan and follows the story of a brother and sister (older sister, younger brother, but both young) who attend a convention for robots. During their visit, a massive earthquake hits Japan that kills thousands, and they team up with an older woman to make their way back home. It's a sad story, but I don't want to go into detail about it and ruin it for anyone.
Unfortunately, I don't remember the title of it. Does anyone know if the anime I'm talking about?
