Intro. You walk along a street towards home when a notebook suddenly falls from the sky. Reality Note is on the cover. When you pick up the book you hear a voice that sounds like a cheeky girl. She says "hey, you! I am Mira, a reality fairy. With this book you can use my strength to change reality according to your will. Just write what you want in and it gets true. Well then entertain me ~!" The voice disappears. Is what she said true and what will you do now?
