Beltrand de Bosque serves as a squad commander for the royal knights of the Hortensia kingdom, charged with upholding order and security in the capital. When displaced Dayereh twins required aid within the city, he oversaw their transfer to a local orphanage for shelter and care. Beltrand leverages a prior professional association with Maurice Baudelaire, a former Knight Templar of Hortensia. This connection enabled their cooperation during the twins' situation.
