Chicago's hundred Magical Girls, united under a theocratic Empress, plan to expand their territory. Except Laila, Chicago's bookkeeper. Cushy job, couldn't care less about conquest—until she's assigned to Chicago's invasion of St. Louis. Yeah, maybe this "Empire" thing's not so hot. Maybe it's time to get out. But the bigger an empire gets, the harder it is to escape...

[Post-Rebellion] In the frostbitten American Midwest, ragged Magical Girls vie for territory to survive the unforgiving landscape. One such girl is Sloan Redfearn, who wastes away in Fargo, North Dakota, nursing a grudge and watching her hopes slowly die. But when Kyubey approaches with a unique opportunity, she becomes embroiled in a conspiracy that threatens to topple gods.
