demon slayer

A young boy with a bandaged head and wide eyes looks terrified while being held by a figure in a dark cloak, then the scene shifts to a girl in a red and black kimono standing over a fallen blonde boy as lightning crackles around a sword, followed by a boy in a green and black checkered outfit leaning over a wooden dock, then a close-up of a boy with red hair and purple eyes looking shocked in a snowy forest, then a view of a snow-covered forest with footprints, and finally a young boy in a blue outfit running through the snow toward a group of people in the distance.
