Rank: A-Class Sprit

Nia is the ninth spirit that Shidou encountered. Also known as the Second Spirit, she is a Spirit that appeared on Earth some time after the First Spirit appeared and is claimed to be the only one who knows any information about the First Spirit and her whereabouts. At some point, the D.E.M. captured her by unknown means and she fell into a comatose state. She was first mentioned in Volume 7, where Kurumi only decides to help Shido rescue Tohka to create a chance for her to find and rescue her. However, it turns out that Nia wasn't held captive in that particular DEM facility.

Nia has short, ash gray hair and icy blue eyes. Nia's Astral Dress takes on the appearance similar to that of a nun. Her Astral Dress is an ink-colored semi-transparent fabric that completely displays her figure. The collar of her dress takes on the shape of a pen tip, and the middle part of her Astral Dress is patterned as a manga panel, both of which referencing her job as a manga artist. She wears long black laced boots and a black veil that is attached to a pen and a feather duster. There is also a golden cross-connected to a beaded rope, surrounding the waist of the dress.

When she is not using her Astral Dress, she wears a pair of dark red square-framed glasses. Her casual outfits tend to be relatively unfeminine, only wearing dresses on special occasions.

While Nia's powers excel in storing and gathering information, it is much weaker than the other Spirits in terms of outright combat. Her strength is further inhibited by her pacifistic nature, which prevents her from tapping into the more violent potential uses of her Angel. Despite this, her Angel's near-omniscience and manipulation of reality are considered God-like when used at full capacity.
