Ef: The First Tale
Yuko Amamiya (雨宮 優子), a mysterious girl dressed like a nun, and Yu Himura (火村 夕), a mysterious gentleman who is somehow attached to the church where Yuko first appears, are having a reunion in a church during Christmas time. Despite her attire, Yuko is not affiliated with the church. She always appears generally out of nowhere, and disappears just as quickly in various places throughout the story to talk with Hiro or other characters and give them advice. Yuko and Yu 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. Yuko hints of events that are revealed throughout Ef: A Fairy Tale of the Two. After the conclusion of the first chapter, the story cycles back to the prologue and the talk between Yuko and Yu. Yuko ends with her talk about the events in the first chapter. At the end of the second chapter, the story shifts again to the scene with Yuko and Yu. Yuko finishes her talk on the events from the second chapter and says that she misses talking to Hiro, Kyosuke, and their friends. Their talk ends with allusions to the continuation of the story, Ef: The Latter Tale.[3]
The first chapter's protagonist is Hiro Hirono (広野 紘), an already established manga author despite still attending high school. Due to the pressures of his work, he often skips school and puts most of his time into his job as a manga artist of shōjo manga under the pseudonym "Nagi Shindo" (新堂 凪).[4] Writing manga causes him to lose interest in school and focuses mainly on his work in order to earn an income, as usually he does not have much money as it is. While out one Christmas night, a purse snatcher rushes past Hiro on a bike and soon Miyako Miyamura (宮村 みやこ) appears, chasing after the purse thief, taking Hiro's bike without asking to pursue the culprit. She ends up destroying his bike, and later hangs out with him for the rest of the night.
Hiro later meets Miyako again at school, and learns that she is a student of the same year there, but in a different class; she too does not attend classes much because she finds them boring.[4] Miyako has an energetic personality and enjoys doing unorthodox things.[4] She eventually starts to become attracted to Hiro after they start spending more time together, but during this time Hiro's childhood friend Kei Shindo (新藤 景) begins to feel left out and a love triangle develops between the three students.[3] She is attracted to Hiro, and becomes jealous when she finds out how much time he is spending with Miyako Miyamura. Hiro and Miyako eventually become a couple, despite Kei's feelings for him.
The second chapter begins several months after the end of the first. It is now summer, and the story focuses on a new protagonist named Kyosuke Tsutsumi (堤 京介). Kyosuke is an acquaintance of Hiro's and happens to be in the same grade and school. He has a passion for filming, and constantly carries a digital video recorder around with him.[4] On Christmas night, he saw Kei Shindo, who is the main heroine of the second chapter, running down the street and tried to get a shot of her, but a truck passed by, so he could not get a clean shot of the mystery girl. After thinking about the mystery girl, he ends up quitting the film club and agrees with his girlfriend, Emi Izumi (voiced by: Kaori Nobiki (Japanese), Allison Sumrall (English)), to break up.
One day, while filming near the gymnasium, Kyosuke catches sight of Kei practicing basketball for her school's girls' basketball team[4] and becomes infatuated by her image. He desires to cast Kei in an amateur film he is making for an upcoming film festival. Occupied with thoughts of Kei, he sets out determined to get closer to Kei by becoming better friends with Hiro, Kei's childhood friend.[3] Kei is one year younger than Hiro and she attends the same school as him too.[4] After being asked to be cast in one of his films, Kei initially refuses Kyosuke's offer, but agrees to watch some of his previous films. While initially put off by the films, she eventually comes to like aspects of his work. After hanging out together more, the two eventually fall in love and go out together.
Ef: The Latter Tale
Ef: The Latter Tale begins once again with Yuko Amamiya and Yu Himura in the middle of a reunion in a church during Christmas time. Yuko tells Yu how she has influenced people in two separate stories (from Ef: The First Tale). After she is done with this, she asks him to tell her about the people he has influenced. Yu starts to tell his first story, that of Chihiro Shindo; the third chapter begins.[5] Like Yuko, Yu also abruptly appears out of nowhere and disappears just as mysteriously.[4] He often gives advice and warnings to Renji and others.[4] Yu is close to Chihiro and takes care of her. After the conclusion of the third chapter, the story goes back to Yuko and Yu with Yu ending his recount of the third chapter, and goes on to talk about how he and Yuko were separated in the past. Yu starts his recount of the events from the fourth chapter. At the end of the fourth chapter, the story shifts one final time back to Yuko and Yu. Up to this point the two have been recounting individual tales to each other. The meaning of the overall title Ef: A Fairy Tale of the Two is revealed to be in connection with Yuko and Yu.
Like the first chapter, the third chapter is also set in winter, but now focuses on another protagonist named Renji Aso (麻生 蓮治) who is half German, half Japanese.[4]
