Yoshino Hide (nickname Hideyoshi) is your average, everyday teenager, interested only in fashion, snacks, and her afterschool free time. She's destined to fail her next history test without some sort of miraculous intervention, so she stops by the local shrine to offer up a prayer or two to any deity that might be listening. Her prayers are interrupted by a mysterious blue light that engulfs her and leaves Hideyoshi stranded in a strange new world that appears to be feudal Japan. All the inhabitants of this world, however, including feudal warlord Oda Nobunaga, are women! Now Hideyoshi finds herself on a quest to gather the pieces of the Crimson Armor and help Nobunaga conquer the land! Contains episodes 1-13.
