That is the case for the living things, and I truly sympathize with them. The realm of my origin is not as strict with travel, though typically, one does not go from another realm into this one; this is especially the case for myself, who would be scolded quite harshly if witnessed away from her post.
However, there is a loophole I have discovered: I may allow a small component of myself to depart to earth while the majority of my being remains here. This way, I am still capable of completing my assigned task, and I can help the lost girl, too. It is my duty to guide souls, after all.
Speaking truthfully, I could ask my superiors to resolve this, but I wish for them not to know of this incident. It is still merely my first aeon on the job.
