Modern-day student Yoshiharu Sagara is thrown back into Japan's Sengoku era to find its famous warlords reborn as young women. He watches a man die in front of him, learns too late that it was Kinoshita Toukichirou, the future Toyotomi Hideyoshi, and steps into the dead man's place in service to Oda Nobuna after saving her life. Drawing on what he knows of real history, he helps the ambitious Nobuna hold her home province of Owari against the warlords closing in around it. This manga adapts the original light novel.
