Atticus

Atticus is a guardian angel who has been assigned to watch over many different humans over the millennia.

He is asked to only intervene when commanded to by authority but his soft and gentle spirit often finds it difficult to hold back when he sees someone suffering, and simply watching it happen tends to traumatize him, so he is often simply assigned to children in happy situations where he more than likely won't have to face this. 

He also often gets attached to the families of the children he watches over so when they grow up and he is moved to another child, he is usually very upset and struggles mentally for the first few weeks or even months on his new job.

Due to these traits, he is often seen as weak and inferior by the higher up angels and has developed a bit of an inferiority complex due to this but he does his best regardless.
