Atur of Fire
A powerful construct mage from the Atur series that helps Cosmo Entelecheia achieve their goals. Nii's apperance is that of a demi-human with Hellas race characteristics (dark skin, white hair), and has a relax personality outside of combat situations, but deadly serious in them where she uses powerful fire techniques. Together with Secundum, Tertium (Fate) and Septendecim, she fought Nagi eight years after the Great War. She is proficient with Fire spells, and was able to cast Incendium Gehennae (Hellfire Conflagration) against Nagi, who had to use almost everything he had to defend againts it. Nii also has some sort of rivalry with Rakan, having mentioned more than once her desire to kill him. Her Incantation is "Mera Lega Mera Sad Nasi Goreng" which in Indonesian, Nasi Goreng is Fried Rice.
- Like her companions, her name is derived from numbers, and in this case from the japanese word for "two" and written using archaic kanji, which means that she was the second generation of her kind.
