Not every orphan would love living at St. Morwald's Home for Children, but Earwig does. She gets whatever she wants, whenever she wants it, and it's been that way since she was dropped on the orphanage doorstep as a baby. But all that changes the day Bella Yaga and the Mandrake come to St. Morwald's, disguised as foster parents. Earwig is whisked off to their mysterious house full of invisible rooms, potions, and spell books, with magic around every corner. Most children would run in terror from a house like that... but not Earwig. Using her own cleverness—with a lot of help from a talking cat—she decides to show the witch who's boss.

Ureshiko Asaba, 26 years old, married. Few people know the fact that she is a magical girl named "Agnes", and she is actually the guardian of the town where she lives. One day she meets Sayaka Kurenai, aka "Cruje", another magical girl appointed by the magic realm as the legitimate sucessor to her position, but Agnes is reluctant in letting her assume because she knows that Cruje has orders to erase the whole place, including its human inhabitants with the purpose of creating a new one. To complicate matters, Ureshiko must deal with the growing distance between her and her husband, Tamotsu, her crescent feelings for Tatsumi Kagura, a young man who is now living as a tenant in her home, and the fact that in the moment she ever kisses a common human, she would lose her powers forever.

Seiya Kanie, a smart and extremely narcissistic high school student, believes that the beautiful but reserved Isuzu Sento has invited him on a date at an amusement park called Amagi Brilliant Park. Much to his chagrin, not only is the location a run-down facility, the supposed date is merely a recruitment tour where Sento and Princess Latifa Fleuranza, the owner of the theme park, ask him to become the park's new manager. Their cause for desperation? As stipulated in a land-use contract, Amagi has less than three months to meet a quota of 500,000 guests, or the park will be closed for good and the land redeveloped by a greedy real-estate company. Seiya is won over by the revelation that Amagi is no ordinary amusement park; many of its employees are Maple Landers—mysterious magical beings who live in the human world and are nourished by the energy created by people having fun. Entrusted with the hopes and dreams of this far-off enchanted land, Seiya must now use his many skills to bring Amagi back on its feet, or watch it crumble before his eyes.
