Stella was orphaned when her parents died in a plane crash. She always blamed technology for that accident. So when an orphanage took her in, she preferred not to watch TV or use any kind of technology. But this made her very bored in the orphanage, so she started using her ability to make her drawings come to life so she could have fun with the things she liked the most.
However, her ability has some limits: her drawings can only last 30 minutes, and she can't make things that she doesn't like like technological gadgets come true
but these limits never stopped her from being kind, so she gave all the fun she could to the other children in the orphanage. And she still does, visiting various orphanages around the planet;

After all, orphans deserve happiness and fun too.
