Aella was born to a god who controls the winds. This in turn gave her the ability to manipulate clouds. She didn't grow up with anyone by her side, so she relied heavily on the other angels who, like her, were disregarded. She grew cloely with Nicodemus, who she considers her brother.

Despite this, Aella has always had the urge to prove herself to her father. She would constantly go above and beyond, resulting in her becoming an overachiever. Because of this, she became reliant on smoking, which has started to affect her abilities.

Aella is always seen wearing tuxedos, as she believes having a formal attire is another way to stand out, rather than wear casual attire. Her monocle is simply for show, and alternates between both eyes. It is said to have been a gift from Nicodemus. In addition, Aella wears her hair up into a bun while leaving out a few chunks of hair.

Adelia is a modest and fair woman who has a calm nature. However, she is prone to anger issues, passed down to her by her father. She tries her best to limit her anger issues in order to keep her composure. These anger issues not only make her angry, but also can lead her into panic attacks. The over-achiever mentality she gained was through her father, so she's afraid to risk anything that might cost her her job. She's prone to break out in the sense of crying sooner than later. Additionally speaking, she'll cry to her significant other, but try her best to keep her emotions repressed, as she doesn't want to stress her partner. She'd rather be affectionate with them than make them worry about her issues.
