After a strange dream of a mysterious ancestor, high school student Yuuko Yoshida wakes to see that she has grown demonic horns and a tail. Dazed and confused, her mother reveals to her a dark family secret: her family is descended from a Dark Clan that was banished to live powerless and destitute by their mortal enemies, the magical girls of the Light Clan. The only way to lift their ancestry's curse is for Yuuko to find a magical girl, murder her, and splatter her blood all over her ancestor's Demon God statue. Fortunately for "Shadow Mistress Yuuko," a magical girl saves her from being run over by an oncoming truck. Unfortunately, Momo Chiyoda happens to be Yuuko's classmate at Sakuragaoka High and is much stronger than her in both strength and endurance. Taking pity on her wimpy assailant, the magical girl agrees to train Yuuko and help her unlock her dormant powers. Now, Yuuko must rise up and defeat her generous frenemy to save her family from the terrible grip of poverty. [Written by MAL Rewrite]

Misaki Takahashi is a regular high school student who is preparing for his university entrance exams. In order to reduce the stress of studying, or so he hopes, he accepts the help of his older brother's best friend, and famous author, Akihiko Usami. However, Masaki is about to find out that Usami's books are of a very naughty genre, and that there may be something naughty waking up inside Masaki as well. Junjou Romantica also follows the story of two other couples loosely connected to Masaki and Usami's "Romantica." Egoist shows the very passionate, but often complicated, relationship between university professor Hiroki Kamijou (whose life has reached an all time low) and paediatrician Nowaki Kusama, who falls for Hiroki at first sight and would do anything to make him happy. The third story, "Terrorist," shows just how obsessive love can become when rich eighteen-year-old Shinobu Takatsuki finally discovers something that he cannot have so easily—the literature professor You Miyagi. There is passion abound as these three couples try to achieve their goals in life while also falling into temptation and anguish with their partners.

As she heads off to her entrance ceremony at Sainotama Girls' High School, Akane Kikuchi muses over her grade school dream of becoming a manga artist and the lack of progress that she has made. When she finally arrives at school, she is surprised to learn that she is once again in the same class as her two best friends: the deadpan and emotionless Shiori Saginomiya and the hyperactive and ridiculous Nozomu Tanaka. Tanaka then comes to the obvious realization that she can't achieve her grade school dream of being popular with the boys and getting a boyfriend by going to an all-girls high school. In desperation, she begins asking the girls in her class to introduce her to their guy friends. Her classmates, however, are anything but ordinary. From a grandmother-loving loli to a reclusive chuunibyou to an overly analytical stalker, each one is given a fitting nickname by Tanaka to accentuate their weirdness. And so begin the wasteful days of these high school girls, each day kicked off with a simple question: "Hey, wanna hear something amazing?" [Written by MAL Rewrite]
