Yuna Lunafreyja A young 19 year old woman, who mothers a child, Noctem Lunafreyja. Her life wasn't quite a utopia, but her son was the light in her darkness. When was taken, she lost all reason and ability to smile. She no longer enjoys dueling, but she hates when cards are disrespected. She let herself become infected with the Starscourge Virus so it can help find her son, even if it meant becoming a Daemon. She has a very serious demeanor and doesn't talk often. She deeply treasures her "Rouge Noise" card, as it is the only link to her son she has left.

Starscourge A primordial virus that predates time. This virus isn't just limited to infecting people, but animals, plants, even the ozone layer. This particular virus has joined forces with Yuna to help find her cold, at a price of using her as a host, specifically choosing her because of her skill.
