On Christmas Eve, Hiro Hirono runs into Miyako Miyamura, a frivolous girl who "borrows" his bicycle in order to chase down a purse thief. After Hiro finds his bicycle wrecked and Miyako unconscious, the two unexpectedly spend their Christmas Eve together, and when they discover they go to the same high school, their accidental relationship develops even further. This sparks the jealousy of Hiro's childhood friend Kei Shindou, whose pure approach to life catches the eye of Kyosuke Tsutsumi, a womanizing photographer searching for the perfect shot. Elsewhere, Renji Asou, a boy who dreams of being a girl's knight in shining armor, has a chance encounter with Kei's twin sister—the overly shy Chihiro Shindou, who spends her time reading alone—at an abandoned train station. The two quickly become friends and eventually decide to write a novel together. However, when Renji discovers Chihiro's secret, a disability that causes her to have an eternally ephemeral memory, his childish ideals will be put to the test. Guided by two mysterious adults, these youths' relationships intertwine in a heart-rending tale of love, rejection, acceptance, and memories.

In a story set years in the past, Himura Yuu is a studious and diligent young man intent solely on maintaining his top academic position at Otowa Academy. One day, he meets a mysterious girl named Amamiya Yuuko, who, to his surprise, recognizes him. Memories of a distant childhood, memories rather left forgotten... meeting Yuuko again will force Yuu to confront the regrets and sorrows of their collective pasts and presents. In the present, Kuze Shuuichi may seem like a womanizer, but upon closer inspection, is a man who would rather be left alone. Hayama Mizuki, however, is not the type of girl who would let him be, especially after hearing the beautiful sounds of his violin performance. As Mizuki attempts to become closer to him, Kuze attempts to push her away—the tale of their budding relationship is darkened with undertones of an imminent tragedy.

Tatsuko of class 5-1 is really excited about the upcoming school sports festival, her proposal for a new "Eel Scooping" event is less than enthusiastically received though, especially by Suzuka. Illya mentions the main event dance to Miyu, and as teacher Taiga Fujimura points out, it entails a huge reward, but will require quite a bit of practice. And so the close friends: sarcastic Nanaki, level-headed Suzuka, excitable Tatsuko, energetic Illya, shy Mimi, and reserved but athletic Miyu are off to win the dance event for the honour of their class and for Fujimura, who seems to have some saucy bet going on that she most definitely needs to win, or so the girls misunderstand.

The new "slapstick" story will depict Komugi-chan and her rivals as they juggle their daily lives as students, idols, and magical girls "with laughter and tears." Komugi Yoshida is a somewhat clumsy second-year middle-school student whose strong point is her spiritedness. She performs as an idol like Kokona Saionji (her classmate and close friend) and Tsubasa Kisaragi (an idol who dresses in male clothing). However, unlike Kokona whose popularity is skyrocketing and Tsubasa with her charisma in male attire, Komugi's only gigs are low-end ones like those at the local shopping district. Still, Komugi has her "dream" as she lives her dual lives as a idol and a middle school girl. One day, a mysterious injured creature named Usa-P appears before Komugi. Komugi gives Usa-P medical treatment, and Usa-P, in consideration of Komugi's kindness, asks if she wants to be a Legendary Girl who can use magical powers. Having become a reluctant Legendary Girl, Komugi battles strange masked figures who suddenly appear! As a newly deemed Magical Nurse, she fights still more waves of masked figures. Meanwhile, a Magical Maid, a Magical Sister, and more also appear to make it a three-way battle!? Can Komugi handle the three roles of middle school girl, idol, and Magical Nurse? And, what lies ahead in these battles and her "dream"...?!
