260 fictitious books [/]
All the books that the user puts out at the counter are recorded in the search machine, and you can browse the information of 260 non-existent books. You can also enjoy it as a fictitious book gallery, as there is a tendency for works by author and publisher.

Change the fate of the user [/]
Depending on the player's choice, the users who visit the library, the titles of the books to borrow, and the lines will change.

Lending history speaks as much as you can [/]
Since this is a library, many users have few words, but you can estimate your personality, hobbies, and occupation from the books you borrow.

You can see the person correlation diagram [/]
Profiles are set for all 30 users. They seem irrelevant, but some people gather in the same library in a local city, and some are connected. You can't find all the connections in a round of play. Please try playing repeatedly.

The mystery of "Cotonolia" [/]
There are several users who say the word "Cotonolia", but you, the player, don't know what it is.
Small mysteries pile up in parallel with normal work, and the truth is revealed at the true end.
It's a calm and light game as a whole, but it also has sci-fi, occult, and mystery elements little by little.
