Appearing even older than greater devils, they are the voluptuous highest class of devil.
Though it is unclear if it is because of their older apparent age, they have the longest lifespans of all devil species, and it is not uncommon for members to live several centuries.
However, due to their extremely long lifespans, they are quite calm and composed, and beyond playing pranks.

They are largely similar to lesser devils, except they have the bodies of humans in their late teens.
They are not more mature than lesser devils, but rather their own devil species.
They enjoy dressing in human fashion and venturing into the city at night to play rather malicious pranks.
However, because their actual age is greater than their apparent age, much like lesser devils, they are out of touch with fashion trends popular among younger people.

With horns on their heads, bat wings on their backs, and tails with arrowhead-shaped points, this non-human species has a truly devilish appearance.
Though they appear to be human children, they are actually fully grown, and their apparent age is not necessarily their actual age.
They enjoy playing pranks, such as teasing and scaring others, and they can even use simple hypnotism techniques.
However, their physical abilities are similar to those of children, making them weak to counterattacks.

Kobold
A non-human species with doglike qualities.
They have dog ears and pads on their hands and feet, and short hair covers their bodies.
The entire species jointly owns rich mineral deposits, and they are among the wealthiest of non-human species.
They are extremely friendly toward all species and use their aforementioned wealth to operate service facilities for other species in all parts of the world.
All members of the species take daily walks in the morning and evening, but these so-called "walks" are long-distance runs, and it is not unusual for a kobold to cover over 50 kilometers in a single day.
