The kobold is a sprite of German folklore. Although usually invisible, a kobold can materialise in the form of an animal, fire, a human being, and a mundane object. The most common depictions of kobolds show them as humanlike figures the size of small children. Kobolds who live in human homes wear the clothing of peasants; those who live in mines are hunched and ugly; and kobolds who live on ships smoke pipes and wear sailor clothing.
Several kobolds are summoned by Akito using a lesbian orgy early on in Tokyo Revelation, where they possess the girls and attempt to capture Saki. After they fail thanks to the ninjas, they return to their masters Gagyson and Akito. Akito later uses them to help capture one of the ninjas and Saki by surprise, but eventually stop following his orders after getting the girl and beat him up on Gagyson's orders. They are then sacrificed in the summoning ritual used to bring Ose to earth.

Kobold is summoned from Joe's app. Being the first demon that he must contract, it proves to be too strong for him and he retreats, dragging the party into his battle and forcing them to seal the contract by happenstance.

Shortly after the subway crash, Hibiki and Daichi examine the area only to find several hostile Kobold roaming around and eating the corpses and attacking the survivors. It is presumed that those Kobold are summoned from the miasma created by the dead Nicaea users' cellphones.
