A little girl angel who is very cute and interesting, despite having a small part in the story.  She pretty much lived in Heaven's equivalent of the slums, starving and poor and all that.  One day she happened upon the coffin Katan was being kept in and tried to help him, telling him that they would go to a new, pure world together.  Dobiel and his men (people who were trying to assasinate Rociel and those associated with him) took her as being an enemy and shot her, effectively killing her. ^^; Rociel shows something resembling pity when he offers to give Tialiel some of his blood so she could live on, afterwards realizing that since living that way was not really living, to just give her a peaceful death.  

As another note, Tialiel is the Angel of the Future. ^^;
