Odonel

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

Appearance
He dresses typically in the Pillar uniform being a trenchcoat. His whole head is wrapped with a bandage with a symbol imprinted on it, and a chain binding his body. He's almost as short as Nāga. Also, unlike most male members, Odonel has no gills present on his "face", though they may be under the bandages, they don't seem to protrude from them.

Personality
Odonel is is shown to be the intelligible one out of the Pillars. While his current "homeroom teacher" Takahashi begins to freak out at his "abnormal students", Odonel calmly explains to him who the Pillars are and even goes as so far to explain allocated ranks.

Mobichi Arc
Odonel goes out to eat with Agiel and Hecadoth. During the meal, Hecadoth seemingly falls unconscious and Odonel asks what is happening. Sometime later, Hecadoth returns to normal but Agiel enters the same unconscious state as he previously did. Confused, Odonel asks what is happening.

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.

Odonel 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. Upon seeing one of the teenagers, Odonel begins to vaguely recognize him; Xoblah informs him that the boy is Furuichi. Eventually, he 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.

Later, Odonel is carried out of the hallways by Agiel.
