I’m back.

A character with black hair and red eyes looks out a window at a red moon and silhouetted figures, then the scene cuts to a dark figure leaping through the night sky with a glowing red blade, followed by a close-up of the character's intense red eye, then a silhouette of a figure falling, and finally a red and black silhouette of a character lunging forward with a blade toward an opponent. The setting is a dark, nighttime environment with a prominent red moon and a cityscape.
