Matthew

Matthew was an applicant for the 287th Hunter Examination.

Matthew overhears the instructions of the Captain to Gon and his friends in Dolle Harbor and stalks them. On the way, they are forced to stop in a desolated alley by the Quizzing Lady and a bunch of masked people. The old lady asks them a dilemmatic quiz, for them to answer in 5 seconds only. Matthew suddenly steps in and volunteers to answers first in order for him to set traps. He gives the old lady his answer and in return the lady lets him through; however, the path is false, and, according to Kurapika, Matthew is attacked and possibly killed by a monster.
