A girl trips into a magic spell and lands in the Sengoku period surrounded by all the famous warlords, except they're women and inexplicably attracted to her. The show knows exactly what it is: a time-travel excuse to dress up historical figures in bikini armor and make jokes about it without pretending to be anything smarter. It's dumb in the way that feels intentional, like watching someone commit fully to the bit for thirteen episodes straight, and that commitment is the entire appeal.

Hideyoshi is an ordinary middle school girl who seems to attract trouble wherever she goes. Before an upcoming test, she visits a local shrine to pray, sees a blue light inside and finds a stranger casting a spell. When she trips on a bell and crashes into the shrine, the stranger catches her, the spell spirals out of control, and she is sent back to the Sengoku era. There she meets Akechi Mitsuhide and Oda Nobunaga, and she discovers that everyone in this world is female. Nobunaga dreams of uniting the land under her rule, and Hideyoshi decides to help her find the Crimson Armor, said to let its wearer conquer all of Japan. Adapted from a pachinko game, the series mixes action, comedy, ecchi and sci-fi.
