Power of Slug

A character with long white hair and a dark blue coat runs across a wooden structure in a forest, then stops and turns to face the camera as a large, dark, segmented creature lies on the ground behind them. The scene shifts to a battle between two characters in a ruined city, where one with dark hair and a white coat clashes swords with the white-haired character, creating sparks, before the white-haired character is shown running through the forest and stopping to look back at the fallen creature.
