A young boy in a red and blue vest holds a flashlight while a small dog in a purple helmet flies beside him in a dark environment; the boy's expression shifts from surprise to concern as the dog looks at him. The scene cuts to a group of knight statues in a dimly lit room, which then transform into a sequence of anime characters, including a white-clad warrior and a character in a purple suit, who appear to be fighting or dancing in a stylized manner.
