She is also an Emanator of the Trailblaze. She has a great interest in outer space, and is often seen as a doting teacher figure for the Astral Express crew. Intelligent and caring, but a bit aristocratic, obstinate yet yielding, she is also slightly flirtatious, seeking a companion to journey amongst the stars with her.
