[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/Akutabe-no-eyebrows_5758.jpg]]
->Voiced by: Creator/DaisukeNamikawa

Akutabe is a detective that specializes in using demons. He is [[BrainyBrunette very knowledgeable in the occult]], and uses this knowledge to overpower the demons, even enabling him to block a powered up "divulgence" spell from Beelzebub. He is Sakuma's employer as well as a mentor. He will summon demons to do his bidding and will often mistreat them if they annoy him or mess up their assignments. He is shown to be cruel and rather sadistic, causing even demons to be afraid of him.
----
* AuraVision: A very dark one.
* BadBoss: Just look how he treats the demons! [[TheApprentice (Exception for Sakuma)]].
* BadassBookworm: He's always reading something, ''anything'', and when he gets mad it leads to a ThrowTheBookAtThem moment.
* BastardBoyfriend: Well, [[ClingyJealousGirl Undine]] ''does'' think she's in a relationship with him...
* BrutalHonesty: Gives one hell of a speech to Azazel during his DespairEventHorizon, and the sad thing is (Or not) he is exactly right in what he says.
* BrainyBrunette: One of the things that makes him so powerful is his vast knowledge of the occult.
* ColdBloodedTorture: As punishment for the demons.
* DeathGlare: Always.
* [[spoiler:DarkSecret: God help you if he suspects that you know it...]]
* DynamicEntry: Performs one at the end of [[http://i.imgur.com/a0XdZMZ.jpg chapter 63]].
* EvilMentor: To Sakuma.
* EvilSoundsDeep: His voice is usually a deep one, but he [[PlayedForLaughs temporarily changes to a more kind and innocent tone when trying to convince Undine to sign the contract.]]
* FaceFramedInShadow: Except that it's perpetual.
* GlowingEyesOfDoom: Whenever he's pissed off, especially if the demons mess up his assignments. Often combined with RedEyesTakeWarning.
* HellishPupils: Even more in the manga.
* HeroicComedicSociopath
* IconicOutfit: In-Universe. [[LimitedWardrobe Almost everyone recognizes him because of the hairstyle and the suit.]]
** Even in the second OVA Azazel pissed his pants of the sight of a guy with spiky black hair and a black business suit.
* ImpaledWithExtremePrejudice: He impales Azazel, Beelzebub and Salamander ''[[ImprobableWeaponUser only with Sakuma's umbrella.]]''
* IdiotHair: From all the silly characters on the series, it is ''him'' who has an ahoge.
* {{Jerkass}}: With nearly everyone he meets. [[ShipTease He seems to have a soft spot for Sakuma though...]]
* MessyHair
* NominalHero: Or VillainProtagonist?
* NoSell: He can casually deflect Beelzebub's ultimate attack one handed.
* NotSoStoic: When he finds the landlord lady stole one of his grimoires. [[ClusterFBomb He wasn't happy.]]
** Also when Moloch's younger brother found out something about him that he really wanted to keep secret. He ''really'' wasn't happy, to the point where he gave Moloch a heart attack.
* OccultDetective
* OneHitKO: Most of his punishments towards the demons.
* OnlyOneName: His first name, if he even has one, has not been disclosed yet.

* PerpetualFrowner
* PowerFist: Occasionally he will use his fist for whatever rage he might have. And somehow his right hand always seems to have a dark aura...

** At one point Koutarou asks Azazel if he knows Akutabe's taste in porn, and Azazel says he does... and he picks a bondage video featuring a Sakuma-lookalike.

* TheStoic: He has two basic facial expressions: stoic and pissed off.
* StraightMan
* SurroundedByIdiots: He seems to be the most competent character in the series.

* WhatTheHellHero: Talks down and coldly brings Azazel down to earth by telling him how can this guy, a demon, be such a little bitch, whining about everything and expecting kindness and gratitude from humans, and relying on their praise.

* WouldHitAGirl: He kicks Undine off him with absolutely no regret. He also has no problem with piercing Sakuma's finger, causing [[HighPressureBlood gushing blood.]]

* BadassBookworm: She can cast a spell which can make Azazel ''explode'' in a million pieces, causing Beelzebub to be terrified of what she has become.
* BerserkButton: Sakuma has a strong sense of justice. Azazel learns this the bad way.

* IdenticalStranger: A soldier mistook her for a woman he fell in love with while he was at war. They look exactly the same, the only difference being the clothes.
* KarmaHoudini: No matter how much of a disaster or stupidity she may commit, Akutabe never seems to get angry at her neither punishes her. While he ''will'' at least punch someone for messing up something, he never lays a finger on her. Some of the demons even lampshades this.
* HardDrinkingPartyGirl: She gets drunk easily and even says that "she can't refuse a drink".
* HighPressureBlood: When Akutabe cut her finger to make a demon contract.

[[LaserGuidedKarma is given a cube of fat.]] [[YouBastard Rinko tells the visitors that he's been having that sacrifice for a long time,]] [[KickTheSonOfABitch making it succinctly clear that Akutabe's offices are done with him and will not have any of his shit]], if their treatment of [[spoiler:Incubus]] didn't make it anymore clear. [[ParentalAbandonment His mother and Kiyoko are horrified and pretty much disown him when he eats it in absolute shame.]] [[HumblePie He even sheds a tear.]] [[AssholeVictim And he had every second of it coming.]]

->Voiced by: Takashi Taniguchi (First season), Creator/JurotaKosugi (Second Season)

Ruler of Heaven and Angels. He has told angels to go down and fetch grimoires so that demons can be killed, properly. Bit of an odd guy, with a juvenile sense of humour and mastery of ImpossibleShadowPuppets. Really doesn't like angels who fail him.

* RedEyesTakeWarning: When angry, he gets a pair of expressive eyes and a symbol on his forehead.
* StopWorshippingMe: Seems to get frustrated at how the angels do nothing but fawn over him and agree all the time. He does he concedes it a great disrespect when angels fail him though.
