Tiana

A mischievous fairy who played scared people at Ayano's school, causing everyone at the school to think that a ghost was haunting the place. Tiana later approaches Kazuma about a treasure that was stolen from the king of the fairies, and hires him to retrieve it. Though she is able to prank Ayano and her friends quite successfully, Kazuma is able to handle her without a problem from the first time they met. She serves mainly as comic-relief.
