Time Skip Mao-chan

One day, when I picked up a mobile phone that had fallen on the street and was playing with it, I found myself traveling back in time to the Sengoku period, when Nobunaga was still alive! And now that he's inside the body of Nobunaga's vassal, Ranmaru Mori, it's a big deal. Even as they are having a great time, the fateful incident ``Honnoji Incident'' approaches every moment... What about Mao at that time? What about Nobunaga? What about Ranmaru? A unique time slip romance!!
