I was hoping not to cry I heard about this anime recently. This anime is amazing and haven't watched a anime that left me heartbroken at the end except Devilman Crybaby.
I figured one of the kids would die,but holy crap when he put his little sister's items in basket next to his sister's body and cemented her, I burst out crying. Then when went back to read the plot on wikipedia and the brother had died too, which is shown in the beginning, I cried even more.
