Puerilis Goetia

Malthus: blah blah leadership and confidence
-Although Malthus shows signs of good ideas early on, he balks under pressure and doesn't like the idea of being in charge. Over time he learns how to be calm and take command without backing down due to fear.

Leraje: blah blah opening up and expressing feelings
-Leraje hides his real feelings with a smile, even from the other demons. When that causes a problem with both humans and demons (big problem!) he learns that admitting weakness and negative feelings is natural.

Paimon: blah blah trust and friendliness
-Paimon keeps to himself much of the time, allowing the others to handle battles and barely working with them outside of combat. Gradually he's convinced that other people are worthy of respect and that he can accomplish more and be happier if he works alongside them, though he's still fairly reserved.

Barbas: blah blah teamwork and appreciating his talents
-Barbas's talents don't lend themselves naturally to combat, but he's always throwing himself into battle and getting hurt. He learns that he can contribute to the team effort and have a part in their success without trying to do things that he's not suited for, and that his own talents are worthwhile.

Aim: blah blah honesty vs white lies
-Aim is naturally bad at lying to his summoners and to anyone. This is a problem for a demon hiding among humans. Over the course of the story, he becomes better able to fool others, and in the end is able to tell a lie in order to protect the other demons. (Yeah I know his moral sucks. I'll come up with something else for him too.)

Malthus
Normally in the shape of a stork, Malthus is now in the form of a human boy. He can create weapons and ammunition, as well as barriers and shields against an enemy. He is awkward at speaking to others, and is determined in all things, including succeeding in the difficult situation he’s gotten into. The unofficial leader.

Leraje
Leraje is a demon who has not yet given up the habit of always wearing green, even in a young boy’s form. He is a skilled archer, and his arrows cause gangrene wounds when they strike true. He puts on a good show of being noble-spirited and gallant, particularly towards girls as that’s how he thinks human boys act... it’s hard to tell exactly how much of that is an farce.

Paimon
Though his normal form is of a man who rides a camel, Paimon chooses to take the form of a young girl for his disguise. His powers include creating familiars, controlling wind and water, and commanding others. His interests are mostly towards studying the knowledge of Earth, and he socializes even less than the other demons. Though he is technically the highest-ranking demon present, he has no interest in leading.

Barbas
Originally in the form of a lion, Barbas now takes the shape of a boy. His powers include causing or curing diseases, changing others’ shapes, and controlling mechanical objects. Like a lion, he is brave - sometimes verging into recklessness, as his powers are often the least combat-oriented of the group and the least able to take out a monster without help.

Aim
Once a demon with three heads - a serpent, a man, and a cat - Aim now only has one head in his disguise as a human boy. He summons and controls fire to a great degree, and is the strongest of the group physically. Cheerful in disposition, he takes great pride in his quick wit, but finds it difficult to outright lie and is having a great deal of trouble pretending to be human.
