Fenrir is a lady of a few words, her quiet, reserved, and aloof nature generally irritates or intrigues others. She doesn't tend to like being around people other then Kaname, and sometimes his family. She isn't generally violent, though will not hesitate to harm another person. She is generally passive and shows lack of empathy though really this is only because she has no interest in people at all.
Much like that of a ninken, Fenrir has heightened senses, such as smell and hearing, along with the ability communicate with with humans. She is able to sense chakra with her nose, which allows her to judge an enemy's strength. In addition to this, she is able to use the wind and water natures.
(To Kaname) "Why should I trust you?.......Last time I trusted a human.......I was sealed away.
In Norse mythology, Fenrir (Old Norse: "fen-dweller"), Fenrisúlfr (Old Norse: "Fenris wolf"),Hróðvitnir (Old Norse: "fame-wolf"), or Vánagandr (Old Norse: "the monster of the river Ván") is a monstrous wolf. In both the Poetic Edda and Prose Edda, Fenrir is the father of the wolves Sköll and Hati Hróðvitnisson, is a son of Loki, and is foretold to kill the god Odin during the events of Ragnarök, but will in turn be killed by Odin's son Víðarr.
