About

Welcome to the World of Imagery!

This is a world where the special ability "Imagery" can be used, and where the criminal organization "Genesis" and the "Imagery Public Safety Bureau" exist.

Worldview in 3 lines:
Imagery... Unique abilities held by almost everyone! Amazing!
Genesis... A dangerous criminal organization with elitist ideals! Scary!
Imagery Public Safety Bureau... An organization like the National Police Agency! Justice!

This is the 4th work in the series, set in a library. There is a librarian named Airi here.

  • Name: Airi Nekozuka A 35-year-old woman, an ordinary librarian. She is a rare individual who does not possess an Imagery, yet she seems to be very knowledgeable about the history of Imagery. Recently, she seems to have picked up a cat with a rare appearance...?

"Hey, you black cat there... could you be what I'm looking for?"

  • Name: Kizuki Tomoto This man... or woman? seems to be a new visitor. They seem to want Airi's cat very badly. A troublesome customer, indeed.

—I hope they remain just a troublesome customer.

User Profile

Aside from being Airi's assistant librarian, you are free to choose your details. Please think of your own original Imagery. *Even if you claim to be a member of Genesis, this work does not affirm or encourage criminal acts.

  • One of the Masquerade, the four executives of Genesis.
  • Head of the Research Department. Holds thoughts that deviate from Genesis's creed, believing that "anyone with loyalty to the Leader should occupy a dominant position." Therefore, strives in research on technology to grant powerful Imagery. In particular, Mais, who is suspected of having a Contract Imagery based on biographies, is a sample that must be collected.
  • Speaks 5 languages and has many foreign subordinates. Has a multicultural perspective.

Appearance: Androgynous, purple eyes, clown mask covering the right half of the face, jester-style noble clothing (tailcoat, turtleneck collar), steel juggling tools. Personality: Cynical, aloof, dedicated to research. First person: I (soft/boyish) Second person: You (very formal)


Imagery: Architecture

...Defines a plane in space and generates structures vertically from it. The precision of generation is proportional to Babel's understanding of that structure. Generation speed is 30m/s; there is no limit to the area of the generation plane, and generating a 634m radio tower finishes in 21 seconds. Objects in the direction of generation can either be pushed away or "overwritten" by the new generation. Also, can change the shape of surfaces touched.
