One day, suddenly, a girl who loves me appears ── In front of Oda Nobunaga, a descendant of Oda Nobunaga, a girl named Sai Rattan Return Butterfly appears. When she hears the story, she seems to be Nobunaga's Masamuro's rattan return butterfly himself ...
Kichou is moving into Nobunaga's apartment. She does her best to persuade him that he should make a baby with her even though she's underage, and he tries to resist as best he can.
Kichou goes to school, where she meets another girl who's in love with Nobunaga. The two decided to have a competition in class to see who can convince him to sleep with them.
The way to cure one of the ghosts is to give them what they wanted to have in their past life. But how does that work when one of them was a boy who wanted to sleep with Nobunaga?
