Stellar led a very isolated life, only associating with her small team ever since she was young. She never had many connections with other people and was withdrawn from the world. As an Extended, she didn't need to have any contact with the outside world because her sole purpose to live was to be used as a piece of equipment in battle for the Earth Alliance. Only when a young man entered her life did she began opening her heart for that special someone.
