Sagara Yoshiharu discovers that he has gone back in time, to the Sengoku era. On his very first day, he was supposed to die on the battlefield—but he was saved by a man named Toyotomi Hideyoshi. The famous daimyo, general, and politician who united Japan and put an end to the Sengoku era died while saving Sagara. The story has changed. He tries to correct events, but it seems history is slightly different from what he knows. Oda Nobunaga, the famous daimyo, has become impeccably beautiful young woman named Oda Nobuna. Sagara Yoshiharu decides to replace Toyotomi Hideyoshi by taking on his role, and to serve Oda Nobuna, who gave him the name “Saru” (Monkey). He moves forward, rewriting history. (c)
