Coba jelasin Staff dari Daftar karakter The Familiar of Zero dong

is the elderly, white-haired headmaster of the Tristain Academy of Magic. He initially shows a serious side, but is also perverted, as he uses his mouse familiar to peek at Longueville's panties. He is a smart and powerful square mage that Henrietta finds trustworthy. 30 years before the start of the series, he was fighting a dragon but was saved by a man from another world (an American soldier from the Vietnam War) who used a M72 LAW rocket launcher that Osmond dubbed the 'Staff of Destruction'. His element is wind magic. He entrusts the Founder’s Prayer Book to Louise when he learns that she is a user of Void.
