Luigi

He was a poor kid with very very sharp memory which helped Kujo determine the girls who went in the Jeantan Department Store and never go out anymore. Though he helped Kujo quite much during the 8th and 9th episode, he never fails to ask Kujo money in exchange for his testimonies. He was adopted by a well to do family by the help of Jaqueline but sometimes sneak out and return to his old ways just to have a breather.
