Plot
Yoshino Hide, an average teenager, finds herself mysteriously transported to a land that appears to be Feudal Japan, albeit in an alternate world entirely made up of females. She ends up encountering the feudal lord, Nobunaga Oda, and helps on her quest to gather the pieces of a Crimson Armor that will help her conquer the land.

Characters
The characters share the names of various historic figures in Feudal Japan, albeit their given names are spelled out in katakana.


 * Yoshino "Hideyoshi" Hide (日出・"ヒデヨシ"・佳乃)
 * A ditsy schoolgirl who finds herself transported to an alternate Feudal Japan made up of women. She at first struggles to fit in with her new world and often brings a lot of modern ethics to this time, including finding uses for her mobile phone despite not being able to get a reception. She is made Oda's retainer after showing skill with a staff, although she isn't good with combat and can't use magic. She is nicknamed "Hideyoshi" after Toyotomi Hideyoshi.

 * Nobunaga Oda (織田 ノブナガ)
 * A feudal lord who desires to gather pieces of a mystical armor to unite the nations. While very short-tempered, aggressive, and overconfident, in the course of the story she becomes more benevolent, considerate, and caring under Hideyoshi's influence. She wields a large sword and appears to be able to control flames. She habitually carries around a kiseru given to her by her grandmother Nobubasa as a good luck charm, despite never smoking it.

 * Mitsuhide Akechi (明智 ミツヒデ)
 * Nobunaga's humble aide, who is often bemused at her acceptance of Hideyoshi's odd behavior and is secretly infatuated with Nobunaga. To this end, she is prepared to do whatever it takes to "make Nobunaga happy", which is why she is willing to acquire the Crimson Armor set on her feudal lord's behalf. Subconsequently, she is also jealous, at times, with Hide's interactions with Nobunaga. She bears a resemblance to one of Hideyoshi's classmates from her time and is often nicknamed "Akerin" (あけりん) by Hideyoshi due to this likeness. Her weapon of choice is the kunai.

 * Masamune Date (伊達 マサムネ) Ms. Date (伊達先生)
 * A warrior affiliated with Nobunaga and Mitsuhide, who is secretly Hideyoshi's teacher from the present. After witnessing a family member from the distant future arriving before her and then disappearing again, she decided to go back in time to find the Crimson Armor whose legend her descendant had discovered, in order to put Japan's history "on the right track" under the rule of her family. However, she did not know about the Armor's evil influence. Like Hideyoshi, she can't fight and possesses no magical abilities.

After being freed from the armor's evil influence, she realizes the error of her ways and becomes more benevolent.
