Gibungle is a dwarf magician who appears in the series during the party's exploration of a great labyrinth. He is characterized by his brown hair, brown eyes, and beard, and is typically seen wearing a helmet and armor while carrying a shield.

Gibungle's primary motivation and the driving force behind his introduction to the main cast is his long-standing connection to the elderly wizard Morlock. Upon encountering the group, Gibungle addresses Morlock as his master and mentor, revealing that he has been searching for him for over twenty years. This revelation adds a significant layer to Morlock's past, as the aged wizard initially claims not to remember his former student.

While Gibungle is notably a magic user, he also demonstrates proficiency in combat, as seen when he comes to the aid of Saitou and the warrior Raelza during an attack. His abilities as a warrior-mage make him a valuable asset in dangerous situations.

Beyond his initial role as a devoted student reconnecting with his past, Gibungle proves himself to be a loyal and helpful ally to the party. His dedication to his master extends beyond simple reunion; he actively participates in resolving the peculiar and dire consequences of Morlock's adventures. When a resurrection spell on Morlock goes wrong, resulting in a missing body part, Gibungle joins the fairy Lafanpan in a search to retrieve it, directly assisting his master in a time of bizarre need. While not always the central focus of the story, Gibungle is a recurring presence whose actions demonstrate his unwavering loyalty and his willingness to support the group, particularly Morlock.
