Take a half-dozen scantily clad gals, a sixteen-year-old with newfound supernatural powers, and an army of unstoppable enemies… What do you have? Just another day in the life of Tomokazu Mikuri, the bumbling hero of Yumeria! It could have been a dream come true for this girl-crazy loser, but the more time he spends trying to save the world, the more it becomes a nightmare. It doesn’t help that his curvaceous crew of housemates and heroines have taken an interest in super-skimpy swimsuits! But if Tomokazu doesn’t rein in his hormones, the evil enemies will defeat mankind without a fight. On the other hand, if this disc weren’t packed with skirt-chasing, peek-taking, half-naked, bouncing, blushing mishaps, it just wouldn’t be the oh-so-revealing second volume of Yumeria!
Tomokazu Mikuri is an ordinary sophomore in high school living with his older cousin, Nanase, who finds himself in the dream world on his 16th birthday. There he meets Mone, a mysterious young girl, battling a strange enemy called Faydoom. When he awakens from his dream, he finds Mone in his bed! After a crazy day of finding Mone in his room, to school, and then his birthday party, Tomokazu falls asleep and finds himself back in the dream world.
Tomokazu receives a zero on his test and Mizuki helps him study for his makeup test. When the day of the makeup test arrives, he is accused of making the test and text books disappear. He learns that Mone has taken and burned the test and text book leading to some harsh words that send him into the dream world where he meets the mysterious Silk who informs him that the dream world is known as Moera and that he possesses a special talent that will help bring Faydoom down.
Nanase’s younger sister, Kuyou, returns to Japan from America where she and their parents have been living. When Kuyou goes to school with Tomokazu and Mone, Tomokazu finds himself facing an irate Mister Ishikari and his fellow male students ready to pulverize him on the field playing dodge ball. A dodge ball game gone bad sends Tomokazu back to the dream world where he finds Kuyou has also entered where the enemy is waiting and where new transformations take place.
Tomokazu finds himself undergoing special training in order to increase his power and abilities. When he breaks his promise to teach Kuyou to swim and goes to the pool to ogle at girls in swimsuits with Mone and Neneko, Tomokazu finds himself at the mercy of Kuyou’s wrath in the dream world. Sleeping has never been such pain for Tomokazu.
Tomokazu and the girls go swimming at the beach that had appeared in the Dream World in the previous episode. Tomokazu finds out that Mizuki is going to be transferring to a different school, and is sad at losing her. But in the end, the transfer is called off, and Mizuki moves in with Tomokazu.
Tomokazu and the girls enjoy themselves at a summer festival. Nanase remembers when Tomokazu was a boy, and she swore to protect him.
Tomokazu is curious about where Neneko comes from and follows her, to find out that there are two personalities within her: normal Neneko and Neito. Neito is a woman who has reverse reincarnated from the future, and tells him that the future has been destroyed by the Faydooms, and only few survive, but Tomokazu has the chance to transform destiny and change the future.
An aurora appears in the sky over the city. Some of the girls think it’s a message from aliens, but Neito says it’s a sign that the Faydooms are beginning to attack the real world. Neneko disappears, and it turns out that she’s been trying to fight the Faydooms all by herself, so no one else would have to get involved.
Tomokazu searches for Mone's family, which upsets her because she thinks he doesn't want her around anymore. In order to make it up to her, he lets her buy things through the mail, but she orders more than he can afford and he gets a job to cover the expenses as a bunny character in a kid's show.
The Man in Black brings Tomokazu to the main house. Neito and the head of the family reveal that Nanase and Kuyou are Watchers for the family, and they have been watching Tomokazu since he was born. The head of the family says that Tomokazu will need his help to bring about a correct Destiny Transformation. He tells Tomokazu to accept his help.
Silk's identity is finally revealed; Mone mysteriously disappears and the gang goes to search for her. Neito appears and says the final battle is that night. Tomokazu tells Kuyou not to use the Arrow of Destiny, because he can't trust it, and is afraid it might kill her. During the battle Mone appears and a shocking discovery about her is learned.
Tomokazu wakes up in school. Things are different in this new world. He doesn't even remember Mizuki, Kuyou, Nanase, Neneko, or Mone. But luckily Neito finds him, and tells him that this fake world is not where he belongs. Tomokazu starts to remember. He finds Mone, and together they go to the Dream World to fight.
