"Things That Are Precious to a Mage") is a Japanese manga series written by Norie Yamada and illustrated by Kumichi Yoshizuki.

[2] Another story set in the same universe, Someday's Dreamers: Spellbound (魔法遣いに大切なこと 太陽と風の坂道, Mahōtsukai ni Taisetsu na Koto: Taiyō to Kaze no Sakamichi), written and drawn by the same author and illustrator, was serialized in Kadokawa Shoten's Comic Dragon Age.

The main backdrop of the series where all the characters reside is Shimokitazawa, roughly six minutes west of Shibuya on the Keio Inokashira Line.

With the intention to honour a promise made to her late father, she successfully applies for a magic internship in Tokyo and temporarily moves into a boarding house in the city.

Over the course of a summer month, she meets other teenagers studying to become accredited mages, including an initially aloof boy who appears to lack magic abilities.

Under the guidance of their mentors, the apprentices learn more about magic, each other, and life in general as they attend formal classes and work to fulfil contractual assignments for clients.

The composer of the anime soundtrack, Takefumi Haketa, hoped that girls would identify with the lead role and created music which had a nostalgic feel to it, evoking both English and Irish suburbs, but also memories of the European Middle Ages.
