Genius Prismatic Mage

In the slums lived a young boy named Ray who lacked emotions. He suddenly gained the ability to see “colors” that no one else could, and he had the power to control them. One day, he lost his shelter, an underpass, and his friends to a magician. He even lost Niles, whom he had believed in and followed. The emotionless boy swore to take revenge, beginning his search to regain his emotions.
