she seems to be fond of Saito and uses her shapely chest to charm him. Staff Osmond 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. Jean Colbert is a professor at the Tristain Academy of Magic who is interested in history; his element specialty is fire magic. He is one of the few people that Saito have in common with. His interest in technology from Saito's world helped him create dragon's blood (actually gasoline) to fuel an airplane. It is revealed that he was the captain of the magic troops sent to burn Agnès' village, D'Angleterre, 20 years ago, but also the person who rescued her, when he found out the village wasn't "plagued", and devoted himself to atone for the sin he committed. He has an anti-war attitude, and is envious when he finds out that modern Japan is not ravaged by war. He reveals himself as the Flame Snake when Albion sends hired mercenaries to attack Tristain Academy, and sacrifices himself to protect Agnès. In the third season, Colbert surprises everyone as he returns with Kirche to Tristain Academy; he had Tabitha cast a spell to fake his death, and was staying with Kirche's family. He constructed a giant airship called the "Ostland", based on Saito's Zero Fighter. In the novels, Tabitha did not cast a spell on Colbert. Instead, Kirche tricks Agnès into thinking that he is dead. Louise and Saito were also not present during the Academy invasion. He is likely named after Jean-Baptiste Colbert, finance minister to Louis the XIV from 1665 to 1683. Chevreuse is a new professor at the Tristain Academy of Magic. Nicknamed The Red Earth Chevreuse, she specializes in earth type magic.
