Kage, meaning "shadow" in Japanese, refers to the dark silhouette or outline created when an object blocks light. Shadows can vary in size and shape depending on the light source and the object's position. They are commonly observed in everyday life, such as when the sun casts shadows of trees or buildings. In Japanese culture, Kage can also symbolize mystery or the hidden aspects of life. In literature and art, shadows often represent the duality of existence, highlighting the contrast between light and dark. This concept is prevalent in various forms of storytelling, including anime and manga.
