Pick

A mazoku lord serving under Lord Chestra, he was considered the most powerful magic caster in the demon army. His notable fighting technique was to capture souls and seal them in a book labeled DEATH, and then use them as "jurors" to judge his enemies. He was also accompanied by Kohokatsu and Bengo, a pair of talking heads on the epaulettes of his coat.
Pick was killed by Lute during the Great War of Sforzando, before the current time of the series.
