I (Kazuharu Shimozono) am an ordinary boy student with no special abilities. One day, I was called to the student council room by the school broadcast. Waiting there was Oria Kirishima, the student council president, and as soon as she and I were alone with each other, the student council president said, "I was Nobunaga in my previous life! I will attack you!" I didn't know what was happening, but I knew I was in danger, and I ran out of the room. Then an outright gyaru, Karan Yuki, appears, holding my hand and saying, "Are you okay?". She took me to the rooftop. With her hands on my face, she looked into my eyes and said, "It looks like we finally met...?" and she began to take off her clothes. Apparently, they have memories of the past life... but I have no idea what it means. And, I think it's normal, but I have no memories of my childhood, let alone my previous life.
