Synopsis
Shinta Kirishima, a high school student who wants a peaceful reading life with a "life lesson memo" in hand.

Shinta has a troubled constitution that makes mysterious things "see", and even today, because of that, he gets fired from his part-time job. When Shinta, who was in a state of trauma, stopped by the book rental shop "Mangetsudo" that he found by chance, there was a clerk girl Tsukumo who had a big attitude and a girl who saw a stoat at a part-time job! Tsukumo describes himself as an "observer" who records the "blueprints of the world," and instead of telling him why he sees Shinta's mysterious things, he orders him to help with his work.

Moreover, if you don't help, the world will end-that's a book rental shop here !?
