Demon Slayer

A young man with black hair and a green and black checkered haori is shown in profile, then the scene shifts to a large, multi-limbed green monster lying on the ground. The man leaps onto the monster's back, then is seen falling through the air before being launched upward in a burst of light. The sequence ends with a glowing, curved blade slicing through the darkness. The setting is a dark, cavernous environment.
