Though an Humas by birth, Hiiro used his magic to give her an Imp Tribe appearance like his own to make it easier for her to travel. Hiiro lists her among the many beautiful girls he knows. Though she is only a child still.
Nikki was raised by a monster in the demon continent even through she is human. One day the monster that was taking care of Nikki was killed by another monster. When Hiiro found her, she could not control her magical power at all. She was a danger to herself but Hiiro saved her and she became Hiiro's disciple.
