Guuko  

Guuko is one of Count Collection's minions whose main responsibility is to provide information about magic and monsters that the team encounters. She can read ancient languages and often says "Ara" and "Desu-wa" when amused. Despite being oblivious to her surroundings, including danger, Guuko is immune to it. Even if she gets hit, it doesn't seem to hurt her, and Chuzaemon never punishes or trains her. Guuko has chronic luck that attracted a Leprechaun, whom she carries around. Her luck is not contagious to the team, but she occasionally causes painful situations for her teammates unintentionally.
