Yuki Nagato of the Melancholy of Haruhi Suzumiya
Yuki Nagato is a bibliophile humanoid interface that was created by the god-like figure called the Data Integration Thought Entity. Yuki's responsibilities involve monitoring Haruhi and the investigation of an unexplained "explosion of data" three years prior to the present story. She possesses an ability to manipulate her surrounding environment, or "data" as quoted by her. Yuki is very quiet but can speak at length when it has to do with her mission or a problem that has arisen. While she always seems to be engrossed in her reading, she comments that she is only relatively interested in them. Yuki gives hints and aid to Kyon throughout the series. She almost never shows any emotions, but there are times when she shows interest in certain things, such as programming computer games and playing them, as well as reading (in the light novel The Disappearance of Haruhi Suzumiya it is further revealed that she may have developed an interest in writing).
