Mikuru is a time traveler from the distant future who is assigned to investigate the reason behind the inability to travel to any point in time before three years prior to the present story. Mikuru is a soft-spoken girl who almost always willingly follows Haruhi's demands. She is the lowest in her Time Traveler's Committee. She often tries to explain what is going on, but will heavily censor it by saying "classified information." Haruhi loves dressing up Mikuru like a doll, and Haruhi is quite jealous of her and Kyon's relationship.
