Hrímfaxi (月輪神馬 (フリムファクシ) Getsurin Shinme (Furimufakushi)?, lit. "Full Moon Sacred Horse") is the horse of Nótt, the personification of night in Norse Mythology. In the world of Toaru Majutsu no Index not much is known about it. It is not clearly specified as a spiritual item or a beast, though it is powerful enough to allow Marian Slingeneyer to traverse from Japan to Denmark quickly.
