Lytee is a smidge selfish, and less attached to people than your average person. She joined the fight against Neuroi for the pay more than out of civic duty, but she doesn't hurt people out of spite and is not impulsive. She had been trying to scheme her way to a higher position in the local power structure, but only so she had more resources and freedom to use them. She probably won't use anything they give her unethically, at least. Especially if she knows there's a higher authority to answer to.

Gren is curious and determined. Her life goal seems to be learning more things, only to be interrupted constantly by the obligation to help save the world. She's fought bravely and stoically against the Neuroi. She's not prone to anger, and when she does get angry she's perfectly capable of channeling it into something nondestructive. She's a bit impulsive and careless sometimes, and possibly a little lazy, but is careful and cautious with her own magic. She wants her brother back, and after that nothing in particular. She can definitely be trusted to use magic ethically.
