Nadie is normally rather clumsy, and easy to cry. Some would call her a crybaby - and she'd likely agree. She frets about her paintings, her grades, fitting in, the expecations her strict parents has on her. She struggles with low self-esteem, and generally thinks she is not good enough or worthwhile. Even when she accomplishes something great, she tends to brush it under a rug and write it off as no big deal, anyone could have done it. Altogether, she stresses a lot, and gets anxiety as a result.

One night while painting in her studio, she felt a calling, as if a pull on her spirits. Unable to resist, she put down the paint brush and looked around the still-empty studio. She walked out, looked up and down the hallway. Still, she felt... something. Something she couldn't quite explain. Shuddering, she returned to her painting, fully intending on finishing it. She had a deadline, after all! Still, she could not shake the feeling that she was not alone. The shadows seemed to move, whispers filled the room. As she turned, she saw it clearly: a shape of black was lunging at her! She scattered away, barely avoiding the creature, and ran around the room trying to avoid it while accidentally knocking things over - until her feet got tangled in themselves and she fell over. With nothing to defend herself as the shadow crept closer, a surge of bravery she had not felt before entered her and she grabbed the only thing within reach - a paint brush. The determination she felt in that moment filled her with power, with confidence, and the brush started glowing. From it pain the colours of the rainbow oozed, and she found she could paint with it. The shadow creature shied away from the paint, screeching in pain when it hit her. After a struggle, she managed to capture the shadow creature in the canvas she had been working on. In shock, she stared at the completed panting, the contrasting colours, shades, shapes and light bringing new tears to her eyes. From the battle, a gorgeous artwork had been created.

This was her calling. Fighting shadow creatures that lurked around in the city, possessing artists, artworks, and even paint. In her new magical form, she had to break into museums and other places in order to follow trails of shadow in order to banish them. None but her seemed to notice the shadow creatures, or notice how they seemed to leech people of love, joy and inspiration as well as change their personalities drastically.The way for her to trap them, was to use the paintbrush and trap them in canvases, creating beautiful artworks out of them - some of which she was able to use for school, some of which she had to destroy as the raging shadow within was not pacified.
