Sequel to Zero's Familiar.
The Tristain Magic Academy is under attack! Kirche, Tabitha, and Agnes manage to slip away before they're kidnapped, but the situation looks dire - until the person they least expect reveals surprising abilities and a dark past. Meanwhile, Louise is doing everything she can to help the war effort, dragging Saito along on secret mission after secret mission. But the stress and danger make it clear just how little they have in common. Can two people from different worlds really make it work?
