Benjamin Canopus is a First-Class Magician from the USNA serving in the "Stars" unit which is considered to be the most powerful magical unit in the world. He is second in command of the unit but assumes overall command when Angie Sirius is absent. His magical abilities are nearly on-par with the Strategic-Class Magician, Angie Sirius, and it is somewhat stated that he's stronger than Angie Sirius herself when it comes to pure combat ability. He knows how to use "Molecular Divider", a secret technique developed by the previous leader of Stars that weakens and breaks molecular bonds. (Source: Mahouka Koukou no Rettousei Wiki)
