Agiel

is a Pillar General of Behemoth's 34 Pillar Division.

Appearance
Agiel has the appearance of a petite, high school teenager with brown eyes that are widened and long, she has crimson-red hair tied in two braids, she also wears a pair of glasses. She also wears a hat which is crossed between a pirate's hat and a college graduation hat, imprinted on it is a symbol of a snake. She wears the typical Pillar uniform of a trench coat and underneath she wears very skimpy clothing consisting of what seems to be a bikini, much to the distaste of the Red Tails and the awe of the Ishiyama males. She wears a pair of plateleg boots and has several straps on her legs, one of which carries a knife. Around her waist is a belt that is loosely fastened, attached to it is a sheath where she keeps her sword. She also has the Pillar symbol tattooed on her left thigh.

Personality
She is arrogant, and she understimates humans, she doesn't seems to like them either. She also likes to fight those who have manage to proven their strength to her and is willing to abandon the Pillar Division for a rematch. Even so, she is very casual, and mostly only seeks entertainment. She is quite aggressive, and she shows some interest to Kunieda, this is shown when Furuichi made contracts with the demons and accidentally called her.

Akumano Academy Arc
Agiel shows up with Pillars Odonel and Zela when the Ishiyama students sneak unto Akumano Academy's Campus. When two Ishiyama thugs come on to her, Agiel flicks her finger twice and blasts the thugs into a wall. Nene captures Agiel by wrapping her up in chains. She easily escapes the chains saying that she was told to stand down, but the captain wouldnt mind if she killed a person or two. Just as she was about to attack Nene, Aoi stops her attack. Agiel sees that Aoi has a pet, Koma, and senses demonic power coming from him; wondering if he's a demon. Odonel explains about Koma's species' past and how now their are praised as Land Gods on Earth. She threatens Odonel when he says he'll take care of Koma as she says that they are hers to fight. After Aoi says that they should leave their school, she blasts all the Ishiyama students that yell out in support to her ideals. Agiel lets everyone else escape so that she can fight Aoi alone. As they start their fight Koma gets a good hit on Agiel who forget all about him. After she insults Ishiyama Aoi starts to get serious and starts to use a special move as Agiel puts it. She enhances her sword with her Demonic Aura and uses Dark Sword, Bloody Grave to counter Aoi's 100 Cleansing Petals Demon Wear Pretty Flower Storm. Agiel loses to Aoi's technique.

Agiel along with Pillars Elim, Pamiel, Fabas, and Tiriel later confront with Aoi after she had finished her training with Oga at Decapitation Island. She tells them to stand back and watch because she wants to fight Aoi one on one again. Aoi however; activates Ankokubutō and starts to attack Fabas and Tiriel, as Agiel stands back amazed, commenting on her "sweet moves". Pillar Barons Ananta and Vritra show up, and Ananta attacks Aoi from behind. Agiel raises her sword to Ananta's head saying that what was happening was boring. She then says that she's defecting to the Aoi's side.

Agiel says she's leaving her match with Aoi till the end. She extends her arm to Aoi asking can she stand. When Aoi asks if she's for real, she says, For "Super" Real ♥.

Return to Ishiyama High School Arc
Following a series of disappearances in Behemoth's 34 Pillar Division, an investigative team is sent to the Human World to figure out who is responsible for he matter. Four of the Pillar Generals are sent to resolve the issue: Agiel, Odonel, Labed, and Xoblah.

Agiel and the others arrive in the newly-rebuilt Ishiyama High School where they find another Pillar General, Hecadoth, with two young teenagers in a fight. Agiel is the first to notice that Hecadoth is present and she asks him what is going on. Eventually, she and the other members of the investigative team are brought into the fight. One of the teenagers, who is actually a Spell Master, manages to swiftly defeat the four Pillar Generals and he leave them bloodied on the floors.

However, Agiel remains conscious but weakened; ultimately, she ends up observing the new fight between Takamiya and Oga from afar. Agiel eventually witnesses Furuichi's heart being carved out from his body and be subsequently sliced into seven pieces, events that leave her visibly shocked. As the fight progresses because of these circumstances, Agiel begins to see how exhausted Oga is becoming. Fortunately, Oga manages to catch his breath thanks to Tōjō. Tōjō notices the presence of the Pillar Generals in the room and mistakenly refers to Akumano Academy as the "Teddy Bear Academy", which leaves Agiel somewhat puzzled.

She as a pillar of behemoth squad, has many abilities such as strength and speed many times greater than that of average men. She is so physically strong, she can send men flying with just a flick from her finger, or break chains with minimal effort. She also has demonic powers, much like Hilda's. She's also good in fighting with swords.
