85% of the content of this story is taken from the actual game, "Ikemen Sengoku: Romance across time." You will see lines and dialogues and even pictures from the game in this story. It's almost exactly like the game actual route with a slight twist to it. I don't own Ikemen Sengoku and its characters and all the credits goes to Cybird. There are spoilers everywhere and if you didn't read Masamune's route yet, I recommend you don't read this until after you've completed his route.
