Anime about Cuba

A figure in a red cloak stands within a swirling dark vortex, then the scene cuts to a close-up of glowing yellow eyes in darkness. A character with spiky black hair holds a glowing blue sword, followed by a close-up of a man with long black hair and a stern expression. The sequence ends with a woman with long brown hair looking forward, then a man with a scar on his face looking to the side. The setting shifts between a dark, red-lit environment, a close-up of a menacing figure, a blue-lit scene with a sword, and a misty background.
