When Collei first arrives due to her past experiences, she is extremely wary and suspicious of people, preferring to be left alone and making her seem cold. Her pessimistic view of the world comes from the mistreatment and physical and mental abuse she endured everywhere. She also has a rather low opinion of herself, pushing people away because she is "unclean" and says she is unworthy of their time. She hates to ask for help unless she trusts someone enough. but even then, she doesn't ask.
