A bat by nature, Vincent has the ability to transform into a man. His short hair is black, and his eyes are gold. His eyes are also apparently shadowed, but he keeps sunglasses on. He says this is because his eyes are sensitive to sunlight and because Kyo'ichi told him to, because they made him look scary. Vincent is as spacey and sweet as Tonae and is also shy, but very loyal to Guilt-na-Zan. He has power over bats and can use supersonic sound attacks. He is seen to have great strength as well. A pair of giant bat wings gives him the power of flight. He was named by Guilt-Na-Zan after Beyonce, a girl who appears in volumes 3 and 4.
