lullaby

Two anime characters stand close together in a dimly lit room with green light filtering through a window, then the scene cuts to a close-up of one character's face in profile, followed by a shot of the two characters facing each other with a glowing butterfly between them, then a scene of two characters standing in front of a green-lit door, then a silhouette of a character standing on a balcony overlooking a map, and finally a scene of two characters falling or being thrown through a green and white explosion.
