Quin takes the form of a man with a height a bit taller than average. He is a collection of swirling stardust that usually has a blue/purplish hue to it. The color can change at times, sometimes being white or gray or being a deep red. Other than this fact he has no discerning features, his ethnicity and eye and hair color are completely unknown.
Quin is surprisingly upbeat for a person without a proper physical form. He thinks of himself as a miracle and often tells Poiji he's her 'lucky charm'. He has a strong sense of loyalty and justice.
