Keith

Keith is one of the most eccentric mamodo seen in the series. Like all the competitors in the current battle, he is young, although he smokes a cigar and has a low voice. He often makes his entrances singing a gibberish version of Ludwig van Beethoven's Ode to Joy (while normally being blasted halfway through the song).

Keith is very proud of his power, and once thought that he could count himself in the same league as the Four Mamodo Prodigies, who only the adult mamodo could defeat. His defeat at the hands of Vincent Bari disabused him of this, and he considered Bari his rival from then on.
