Aten Gnu is a young girl originally born in Zeth. She was claimed to be quite talented in magic in her school days, having skipped several grades and was said to be an active genius. However, she soon grew very lazy and and became unmotivated to do anything. She loves JAPANese comics and magic vision shows, which has led her to grow leisured over time. She only works when she really has to. Actually, she sets up a very complicated labyrinth and harasses the villagers just for them to leave her alone, as she told Rance "I'd go all the lengths and do all the work just to stay lazy".
