Natsumi is a woman who was mistaken to be in love with Darien, but was really just fixing his car. She and her late husband had a dream to repair an old classic car. She was also being targeted by Hawk's Eye, who extracted her dream mirror and searched it for Pegasus, but was unable to find him. After Sailor Moon destroyed his Remless, Buranko, Natsumi was nearly able to start the car. Though it broke down again, she was closer to fixing it than she has ever been.
