Guuko is one of Count Collection's minions. Her sole purpose is to from a book she carries, providing information on magic and monsters the team encounters and she seems to be able to read ancient languages as well. She is prone to saying "Ara" and "Desu-wa" when amused, and she's always amused as she's rather oblivious to the world around her. Especially the concept of danger, namely in that she is immune to it; in the extremely rare case she actually gets hit it doesn't seem to hurt and Chuzaemon never punishes her or submits her to training. Guuko suffers from chronic luck, which eventually attracted a Leprechaun whom she carried around henceforth. Guuko's luck is not infectious to the team, and she even occasionally causes painful situations to her team mates, never on intention though.
