Vincent Nightray

Vincent is Gilbert's younger brother by one year. As the Vessalius family found Gilbert, the Nightray family similarly adopted Vincent. His left eye is golden like Gilbert's, but his right eye is wine-red and his long hair is golden in color. He loves his brother Gilbert to the point of slight obsession. He has an easy-going personality on the outside and is often seen smiling. However, it is shown that Vincent also has a dark, unstable side.
