As Marianne’s guardian angel, he can only communicate with her inside her mind and lacks physical form, therefore he’s limited to whatever she hears, witnesses or thinks, still he always tries to guide and advise her despite his limitations. However, he can perceive all forms of demonic activity or any kind of unnatural power display that could lead them to find more people like Marianne.
In his physical form he’s clueless and naive, also determined when it’s about protecting others. His fragile and androgynous appearance exerts a special magnetism on others even when he’s not aware of it and the halo that seems to surround him all the time. He’s usually oblivious to human customs or feelings, but when it’s about guiding the others, he becomes a leader full of conviction.
