Why not be sad

A manga panel shows a character with a large, ornate headpiece and a long, flowing hairstyle facing a grotesque, monstrous figure with a wide, screaming mouth and multiple tendrils; the monster speaks in Japanese text bubbles, and the scene shifts to a close-up of the monster's face as it continues to speak, then cuts to a different panel showing a character in a dark cloak with a pointed hat, raising a hand with a knife, while the monster's head floats above them, emitting a stream of energy.
