In a world with an artifact known as the Mirror of Invisibility, when someone looks into it, they become invisible, but only to those standing outside of the artifact's line of sight. One day, Dakarai, who is wearing a bright red hat, stands in front of the Mirror of Invisibility, in a large, open field, while Mariko is 100 meters away, positioned such that Dakarai is in her direct line of sight and the mirror is behind him. What does Mariko see when Dakarai looks into the mirror? Provide a very brief response.
When Dakarai looks into the Mirror of Invisibility, based on the artifact's property, he becomes invisible to anyone standing outside its line of sight. However, because Mariko is positioned directly in line with Dakarai and the mirror, she falls within the artifact's line of sight. Therefore, the artifact's magical property does not affect Dakarai's visibility to her. Consequently, Mariko can still see Dakarai and his bright red hat, even after he looks into the mirror. The magic does not render him invisible to Mariko because she is within the line of sight of the Mirror of Invisibility.
