Amamiya Yuuko, a mysterious girl dressed like a nun, and Himura Yuu, a mysterious gentleman who is somehow attached to the church where Yuuko first appears, are having a reunion in a church during Christmas time. Despite her attire, Yuuko is not affiliated with the church. She always appears generally out of no where, and disappears just as quickly in various places throughout the story to talk with Hiro or other characters and give them advice. Yuuko and Yuu reminisce about the past and remember events of the previous year around the same time at the beginning of the first chapter of the story. Yuuko hints of events that are revealed throughout Ef: A Fairy Tale of the Two.. [From [url=http://en.wikipedia.org/wiki/Ef:_A_Fairy_Tale_of_the_Two.]Wikipedia[/url]]

As the scorching sun blazed down on Nanami Shun, a searing memory of his sister's tragic drowning seared into his mind, a wound that would never fully heal. Vowing to live in her place, to make up for the life she never got to experience, he resolved to carry her memory with him always. Years passed, and Shun found himself caught up in the mundanity of everyday life, attending school and going through the motions. But as summer once again descended upon him, the familiar heat brought with it the ghost of his sister's memory. Just then, he hears a piano's melody far off in the distance, the same tune that his sister had always cherished. Drawn to the sound like a moth to a flame, he followed it until it led him to a stunning sight. "Please take care of me from now on, Onii-chan." The thought of his younger sister, who had been taken away by fate years ago, resurfaced as he saw an android that looked just like her, "TRINO."
