Smudger's friend Huntley Hunter is also frustrated by the prohibition, as he cannot keep a promise he made to his late father. Angered by the unjust world they live in, the two young boys set out to break the new social order—but the uphill battle they are faced with is a lot more than they bargained for.

Naru Ayase is an 8th grader who can see the colors of music when she listens to it. For Naru, who is extremely good at decorating, becoming the owner of a shop like Dear Crown was her dream.

As the united world fights for its freedom against the alien forces known as the Neuroi, human girls with magical abilities—called witches—continue to battle. With the persisting conflict affecting morale, Grace Maitland Steward, a retired witch who still serves in the army, presents a plan advocating the power of music as an invaluable support that can change the tides of war. Unfortunately, her proposal is written off, prompting Grace to find a way to prove the potential of her idea to her superiors. She enlists the help of Aila Paivikki Linnamaa and Eleonore Giovanna Gassion—two witches who have already seen some success as singers—to recruit other witches and form the League of Nations Air Force's Music Squadron. The campaign manages to produce seven promising candidates. Among them, 14-year-old Virginia Robertson, despite having no military experience whatsoever, seems to possess an ability too significant to ignore.
