Jazar

 is one of the Geniuses of the Seventh Hour. In the Nuctemeron, Jazar is called the Genius who Compels Love ; its epithet in Theldesia is currently unknown.

It is one of the Genii who have escaped the Prison of Time with Taliktan's help. Currently, it is residing in Indicus' right eye.

Synopsis
Jazar is first mentioned in Volume 12 : Collapse of the Round Table (its anime equivalent being the second episode of the season Log Horizon: Destruction of the Round Table), while KR is reporting to Indicus. KR's second question, after asking her why she was throwing Yamato into chaos, is "Are you familiar with the name Jazar?"

It apparently seeks to build a world where the most expensive things will be sold at the lowest price.

Abilities
Little is known about its true abilities right now. However, its official description says it controls "mind trafficking/spirit trading".

Trivia

 * Some translations of the Nuctemeron spell its name Jazer.
 * In the anime, the visual effect playing when KR asks the question make it seems as if Jazar reside in her left eye instead of her right.
