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.
He has a habit of carrying around scissors and cutting up stuffed animals with them. Break is often at odds with him, which is fueled by Vincent sending Echo to attack Shalon. Vincent is from 100 years ago. In Alice's memory, a young Vincent is seen walking among corpses, gouging out eyes and intestines with a pair of scissors saying that "it's not his fault", because he was doing this to save his brother. He is also shown to be in alliance with the Baskervilles. It was him who called Zwei out from Echo, telling Echo that she is not required anymore in order to release her other personality.
Recent chapters showed some of his time during 100 years ago. Due to the belief that red eyes will bring disasters, Gilbert and Vincent used to live on the streets where people would attack them whenever Vincent's eye was revealed. This continues until Jack Vessalius found them and brought them under his wings. The brothers then became his servants. He was fond of Jack, who didn't care about his eye and even cut Vincent's hair which was used to hide his red eye, stating that Jack "loves" it. Vincent also called him Master like his brother. It was also shown that Jack tried to introduce the two to Alice since they were in closer age to her. Unfortunately, Alice immediately made fun of Vincent's red eye which caused Gilbert to pull her hair. This incident fueled Vincent's hatred towards Alice since she had made Gill "showed that kind of expression again" and Jack "sighs in worry" and began his habit of taring up dolls (often rabbits) out of frustration and hatred. When Vincent found out about Gil's death and how he will be Glen's next body through a ritual from Alice, he was visited by a mysterious lady (later revealed as Miranda Barma) who told him how to prevent the ritual by opening the Abyss's door. Though he had succeeded in saving Gil, Vincent had caused the Tragedy to happen, making himself a "child of disaster", like how people had been seeing him for his red eye.
The only thing Vince remember about his parents is that his mother sold him and Gil to a freak show when they were young.
