Little D.'s

Little D.'s are lesser demons that reside within the Demon Lord's Castle and serve under Barbatos. Not much is known about them except that No. 1 and No. 4 do not get along.

Appearance
The Little D.'s are all small, shadowy demons with a pair of horns that protrude from the top hats they wear. There are at least seven different Little D.'s each representing the seven different sins. The horns of each are identical to the demon forms of the demon brothers; i.e., the Little D. of Envy's horns match Leviathan's horns.

Personality
In Lesson 25-15, Mammon comments that he thought all the Little D.'s behave like they've "had too much caffeine", though Little D. No. 2 counters this by saying that each Little D. has its own personality and idiosyncrasies.

Story
Note: this section may include spoilers

In Battles, Little D.'s appear as opponents with the Special Skill "SHADOW ATTACK" spelled in reverse; their battle dialogues are also spelled in reverse. Some Little D.'s are also able to take the shape of the demon brothers during battle.

Little D.'s also made an appearance in the Pop Quiz A Surprise for You, but only as possessed bodies under the control of unknown beings.
