First-year Ash Blake is the laughingstock of Ansarivan Dragonar Academy for carrying the school's mandatory dragon-partner brand without a dragon to show for it. Then his partner finally awakens: not as a beast, but as a girl named Eco who promptly starts treating him like her servant. Forced to renegotiate what it even means to be a dragon knight, Ash has to navigate the academy's rankings alongside fellow students like Sylvia Lautreamont and Rebecca Randall while keeping Eco from causing chaos. This manga adapts the Seikoku no Dragonar light novels.
